SUBJECT: INDIA. Appraisal Subernarekha and UP Tubewells II Projects andTechnical Assistance Karnataka Tank IrrigationBack-to-Office Report
Date of Tezms of Reference March 30, 1982Arrival in India April 4Departure from India April 29(for Egypt, see separate BTO report)
Subernarekha Irrigation Project
The purpose of this mission was firstly to accompany a consultingteam - the Snow Mountains Engineering Corporation, Australia-- in theirtechnical appraisal of the Chandil and Ichha dams, and secondly toparticipate in the Bank's final full appraisal mission later in the month.The project, with which the CP has been closely associated throughout,is now expected to go to loan negotiation within the next two months.
In the lengthy "cycle" of preparation/appraisal of the majormulti-purpose project it is of interest to note the nature of the issueswhich have latterly assumed particular importance. They include:
- Conceptual layout and possible alternatives in diversion andcanal systems (which have continued to be debated throughout).
- Level of technology to be introduced (extent of canal lining,operational controls etc).
- Priority and phasing of construction of the various projectcomponents (completion of the whole complex will take someten years).
- Availability of funds (from participating States and from IDA).

Due largely to the shortage .of IDA funds, the first stage oflending will be limited to financing a four-year "time-slice" ofsome $200 million (project cost). By the end of this period constructionof reservoirs and canals will not have reached the stage of bringing anyland under irrigation. This situation represents something of a departurefrom earlier Bank policies, in that it accepts the assumption that theStates will complete and bring to fruition the works initiated throughthe Bank credit (probably with the assistance of a subsequent credit orcredits, but without any Bank assurances that such will be forthcoming).Further, this short initial time-slice does not give the Bank any"leverage" in ensuring that effective water distribution systems areconstructed from minor canal to the fanm, as these works, which are ofcentral importance as far as the Bank is concerned, will not be scheduledfor construction during the first four years. In recognition of thissituation, the first stage project will lay considerable emphasis on pilotwater distribution and land development systems (using temporary pump-lift supply) and training of staff in their desi , construction, andmanagement. These activities will be initiated (probably with CP involvement)early in the project period.
UP Tubewells Stage II
This project has been the subject of much recent debate in the Bank,with particular reference to the perennial question of public versusprivate tubewells. Further, a number of "conditionalities" have beenunderlined in Bank review discussions, relating to the power supply toproject wells, State intentions regarding adoption of the proposed technologyin wells outside the Bank project as well as those within the project, costrecovery (water charges) etc.
Processing of the Stage II project at this time is at some disadvantagein that most of the Stage I wells as yet in service have been operating forless than twelve months. While their technical performance is not questioned,cultivator response to the availability of water has been slow in some areas:in part, this is due to the complete absence of supporting agricultural extension.While Stage I has served its primary purpose as a technical proving groundfor Stage II, the period of maturation between Stages I and II (now to bevirtually concurrent)has proved insufficient to generate a level of actualcrop response data which is reasonably representative of prospective "with-project" conditions. Project analysis is therefore being based uponanticipated production value (and cost) of water delivered to the field, usingwell-established production figures for irrigated crops in the State.The Stage I experience has, -however, strongly emphasized the need for moreintensive extension activities on Stage II. These will involve a "withinproject" extension effort, with demonstration plots in each cluster of tento twenty wells.
With regard to private versus public wells, in the UP situation thetwo.are not mutually exclusive. However, the smaller cultivator (commonlyless than one-half hectare, divided among a number of plots) is not usuallyin a position to own a private tubewell however simple it may be. He mustbuy water from his wealthier neighbour (or hire his portable pump) in theabsence of a public well. He much prefers the public well alternative, whichis also more economical in operation than the private well. This stillleaves open the question of cooperative rather than public ownership .of thelarger type of well. However, the history of such ownership of wells (and
-3-
river-lift systems) has not generally been a happy one in India, althoughvariations on the theme including ownership by a broader based cultivatorgroup (possibly a private corporation) may be worth pursuing.
The mission was asked to explore the reactions of Government ofU.P. to the "conditionalities" under consideration by the Bank, andto report back prior to mounting the final appraisal mission. A lengthytelex to the Bank discussing the situation is attached to the file andIC Management copies of this report. Final appraisal is in progress atthe time of writing (with participation of K.K. Aw Yong, CP). The projectwill probably cover 4,500 wells, or a "time-slice" of half that amount(project cost of the order of $200 million in the former case). Averageunit cost from Stage I (500 wells), including tubewell, transmission linkfrom 33 KV substation, and complete pipe distribution system and outlets,is approximately $500 per hectare.
Karnataka Tank Irrigation
The mission was in continuation of technical support being providedby CP to this on-going Bank credit. The purpose of the visit was to pursuein further detail the development of standard designs for hydraulicstructures for Tank canal systems, the canals in question being in therange of 5 to 20 ofs capacity (0.15 - 0.6 m3 /sec) I/
Prior to the visit a number of existing irrigation design manualswere reviewed. These included those produced from time to time by severalStates and by GOI, also the USBR manual "Design of Small Canal Structures",also the FAO reference "Small Hydraulic Structures". While there is veryuseful material in all of these references none fully meets the need for-a field design reference for canals in the size range under discussion, andcovering the variety of construction materials encountered. It was agreedwith the State that the USBR manual referred to above was the most usefulreference for hydraulic design of project irrigation control works, but wasnot entirely appropriate for their structural design. Portions of thismanual will be reproduced by CP (with due acknowledgement to USBR) fordistribution to project staff. As the USBR standard designs cover canalcapacities extending from 10 to 100 cfs (0.28 - 2.8 m3/sec), structuraldesigns for the lower end of the range (which is the capacity of interestfor the Tank project) are necessarily scaled-down versions of designswhich are more suitable for considerably larger capacities. As an example,all the structural designs are for formed-in-place reinforced concrete.
It remains to develop structural designs more appropriate to thelower end of the canal capacity range (most frequently less than 10 cfsfor "main" canals in Tank projects). It is also necessary to develop designsfor the smaller watercourse structures (around 1 cfs capacity) suited toproject conditions.
During the visit a substantial start was made on these tasks andoutline project designs were worked out with State officers. This action will

be pursued by both State and CP in anticipation of the next visit.
Design of the Minnattuhalla Tank scheme, one of the firstto be prepared for clearance for construction under the project, willalso be reviewed by CP prior to the next mission, with particularregard to the impact on the project of the change in method ofassessment of monthly runoff cleared with Bank at the time of theprevious (February) mission.
Follow-up (Karnataka)
As the project is already much behind schedule completionof standard designs is urgently required. The next mission is plannedfor 14-23 June. It will include field review of canal system layouts,and design and installation of hydraulic structures, in typical projectareas. Completion of a draft manual by end July is aimed at.

SUBJECT: INDIA - Uttar Pradesh Tubewells II Irrigation Project
- Power Systems Engineer- Terms of Reference
1. On May 6, 1982 you will join Messrs. Cunningham and Barber to
travel to Lucknow to review the power sector in Uttar Pradesh (UP) with
special reference to its relationship to the operation of the public
tubewells irrigation systems. Your mission is expected to take about 10
days within the State followed by about 5 days in the Bank's New Delhi
Office for preparation of the report.
2. You will specifically review and report on the following aspects
of the power situation:
(a) the present generation capacity and its limitations and
constraints, plans for provision of additional generating
capacity, and the likely effect of these plans on the
overall power situation;
(b) the transmission and transformation network in the various
parts of the State, its limitations, and plans for improve-
ment of the network;
(c) the performance of the 11 KV system, the advisability of11 KV lines dedicated to public tubewells to ensure ade-
quate power, reliability and availability, and the impact
of private tubewells on the rural power network, particularly
during periods of peak demand and heavy rostering;
(d) economic justification of dedicated power lines if they appear
advisable, and development of the most cost effective alter-
native for providing such service considering operational
objectives of the project;
(e) development of a reasonably optimal layout and design for
such dedicated lines which could allow for their integration
into the basic power system at some future date (when and if
present power supply problems are alleviated) so as to allow
more general service in the area of the dedicated lines;
(f) preparation of full cost estimates (based on (d) and (e) above)
for provision of dedicated power lines to the public tubewells,using either "as built" costs or SEB estimates for a sample of
the networks to support the tubewell systems constructed under
the UP Tubewells I Project.

2. Mr. Cunningham (Irrigation Engineer) will lead the mission andbe responsible for preparing the appraisal report and for coordinating andmanaging activities and input of other mission members. The mission willpay particular attention to progress under UP I, project scale and scopeof UP II, management and organization aspects, project costs and economics(particularly the economics of dedicated power lines), and special issuessuch as water charges, cost recovery, well siting criteria, procurement,and arrangements for smooth transition from UP Tubewells I to II. Themission will discuss with GOUP:
(i) a project period of two or three years and the resultingmodifications to the project scope and scale from that proposed by GOUPwhen the project was to be a five year 'time slice' of their publictubewell program;
(ii) the concept of 'dedicated power lines' for project-financedwells, which would enable the provision of a secure and predictable powersupply to them;
(iii) the reorganization of the Tubewell Wing of the IrrigationDepartment to ensure that the requirements of the project can be met; and
(iv) charges for water, which it appears should be a minimum,to cover full O&M costs with power charged at the so called 'accounting'cost (Rs 0.24/kWh).Mr. Cunningham will also be responsible for the irrigation aspects ofthe project; and will decide what monitoring and evaluation activitiesshould be recommended under the project.

OFFICE MEMORANDUMTO: Dist ibution DATE April 6, 1982
FROM: Mr/ .J.-Tibor, Chief, ASPAC
SUBJECT: INDIA - Uttar Pradesh Tubewells IIPre-Appraisal Meeting
1. It is proposed that the Program Division call a meeting todiscuss the questions which need to be resolved before processingthe above project any further. The present status of the project issummarized in the draft project brief of UP Tubewells II, which hasbeen circulated under separate cover to those on the distributionlist of this memorandum. As discussed in the draft brief, theproposed UP Tubewells II project would construct about 4,300 new publictubewells, modernize about 200 existing wells and connect an additional2,000 existing (traditional design) wells onto 'dedicated' power lineswhich will run separately from the existing rural grid. The projectwould also support a re-organization in the Tubewell Wing of theIrrigation Department. The cost is estimated at about $330 millionover a five-year 'time-slice?.
2. The following issues require attention and guidance frommanagement:
(i) Project Scope. The project scope as summarizedabove and detailed in the draft project brief is within the financialcapacity of GOLT (with IDA assistance). However, the current lendingprogram allocates only a credit of about US$ 90 million for thisproject. The mission needs guidance on what credit/loan amount willbe available for UP Tubewells II; should it be less than that requiredfor the scope proposed by COUP, do we reduce the scale of the project,the time period of the project, or reduce our financial contributionbelow the standard 50% in the irrigation sector?
(ii) Tiiing. The project is a follow-up of UP Tubewells Iwhich was launched as a pilot demonstration of iw tochnologies over atwo-year period .7nt is du.e to be completed about August 1982. UP Tubew>llsII is ready fc)r technical appraisal now. There is evidence that the tech-nology introduced in UP I can achieve its objectives, and can provide atimely, relible and equitable irrigation service which is cost effectiveand efficient. However, due to delays on imiplementating UP I, we and COUPhave less experience in the operation and management of the new technologythan we thought we would have by this point, and it will take at leastuntil the end of the next rabi season (April 1983) before any definiteconclusions on agricultural benefits due to the UP Tubewells I Projectcan be made. However, trends on performance to date, indicate that ifagricultural benefits fail to materialize as planned, it will be due toother factors than the tubewell technology. The issue is to decide the
continued/.....
-2-
appropriate timing of the appraisal of the project. In making thedecision the meeting will have to keep in mind, that GOUP will continue,with or without IDA's help with their public tubewell program at a rate ofat least 1,000 wells per year (not necessary to the UP Tubewells I design).Therefore, if we decide to delay appraisal, what would be the criteriafor deciding when we should appraise?
(iii) Conditionalities. There are certain conditions that areeither technically essential or important in terms of Bank policies thataffect the processing of UP Tubewells II. ASPAC proposes the followingconditions be discussed and a Bank position established prior to the
departure of an appraisal mission:
(a) 'Dedicated Power Lines'. Public tubewells requireadequate periods of reliable power to achieve basic project objectives;such a power demand is quite different from other rural uses. It has
therefore been proposed to GOUP that power lines to new and also toexisting public wells be entirely separate from the existing ruralnetwork.
(b) Exclusivity. It is proposed that (i) all public
tubewells partly financed by the Bank should be to the improved designas per UP Tubewell I Project; and (ii) GOLT be asked to agree thatother new public wells in the State (outside supported Bank projects)should be planned and built to the new designs.
(c) Organization. It is proposed that GOUP be askedto expend and reorganize the Tubewell Department of the ID to facilitatethe operation and maintenance of the project wells.
(d) Cost Recovery. As a minimum, charges for water shouldcover full O&M costs and full "accounting costs" for power 1/.
3. We would appreciate any co-,ments or notice of any other issuesrelevznt to UP Tubeuells II which could be dealt with prior to appraisal.(Please contact John F. Cunningham, Room F410, extension 74619).

FROM: D.E. Campbell
SUBJECT: IMDIA and NE2AL. Appraisal of Subernarekha and UP Tubewells IIProjects. Pre--Appraisal Bhairawa-Lumbini Project.Report Writing, Washington.
As directed in TOR of March 15, 1982 I visited Washington fromMarch 16 to 23 for report writing and review of report drafts forthe above. The status of the projects is as follows:
Subernarekha
A recent change in Bank procedures now requires formal technicalappraisal of Chandil and Ichha dams by a consultant panel before Boardpresentation of the project. This is additional to examination ofdesigns by a Dam Safety Review Panel prior to construction.
Arrangements were made for engagement of a three-man consultantteam who will be accompanied in the field by CP in mid-April. Subjectto satisfactory report by the technical consultants final appraisal willbe mounted in the last week of April, with CP participation.
UP Tubewells II
The project, now in mid-appraisal, is the subject of much discussionin Bank with particular regard to the perennial topics of public versusprivate tubewells, and cost recovery. Four issues have been defined onwhich Bank seeks GOUP assurances before mounting of appraisal (in line withthe new Bank emphasis on "conditionality" in lending). CP has been askedto confirm the GOUP position on these issues in the first week of Apriland report back to Bank, following which the appraisal mission will belaunched in mid-April.
CP has prepared an analysis of performance of UP I tubewellsK.K. Aw Yong), and detailed economic and financial analyses of UP II
(T. Lohavisavapanich), which will be primary inputs to the UP II appraisalreport. K.K. Aw Yong will accompany the appraisal mission.

Summary of Your Discussion with Mr. Arora, DRA onI-arch 12, 1982 (J.D. Roulet's Memo March 16, 1982)
1. Re UP Tubewells II Project and the IDA's objective to seek acommitment from UP, that all future public tubewells in the State beconstructed to the improved standards of the UP I Project (or substan-tially all as a possible compromise). In this context, Mr. Arora cau-tioned that such a commitment might not be acceptable to UP sinceBank-assisted tubewells were about twice as expensive as conventionaltubewells.
2. I am surprised that this statement was not challenged by you orRoulet. For the last three years (starting from Credit 954-IN MaharashtraII) we have been "merrily" lending over $1,000 million for irrigationprojects in India which were all much more expensive than the traditionalIndian designs. We successfully argued in our Region, in the Board and inIndia that the measuring stick to be used for deciding on an investmentshould be its potential performance (properly assessed and measured) andnot only its cost.
3. This is the basis for recommending new and more sophisticatedcanal designs, a more intensive network of minor canals, more sophisti-cated communication equipment in the projects, our insistence on bettertrained and more staff for operation, etc., all more costly than thetraditional way, but hopefully much more effective. Our entire betterwater use program is predicated on the assumption that better performanceat higher cost is a better development option, if it is shown to be moreeconomic, more equitable and easier to operate than the lower cost tradi-tional way.
4. For our more "expensive" public tubewell design, I am enclosingour estimates of costs and performance comparisons.

S U BJ ECT: Mr Wie en's Meeting with Mr Arora, DEA or"-
1. On March 12, 1982, Mr Wiehen met in Delhi with Mr G.K. Arora,Joint Secretary, DEA. Also present were Mr S.C. Jain, Mr S.P. Bajpai Yand I. j.r c (-
2. The discussion focussed essentially on the current status of theBank/IDA operations program. Following is a summary of the main itemsdiscussed:
\.-. Rural Electrification III. This project had been discussed atlength during Mr Arora's recent visit to Washington. In Mr Arora'sview, the main point at issue was the Bank's request thatelectricity subsidies, which in some States had reached a veryhigh level, be gradually eliminated. While Mr Arora was not in aposition to commit his Government and would review the matterwith the Power Ministry the following week, he personally feltthat the principle of reducing and ultimately eliminating subsidieswould be acceptable but hoped that the Bank would be prepared tobe flexible in respect of actual implementation. The situationvaried considerably from State to State. Some like Bihar, MP orTN currently had substantial subsidies which could only be eliminated.gradually. In addition, the central authorities could notunilaterally enforce decisions in matters of this kind and wouldhave to enter into negotiations with each State and individualelectricity board. This was bound to take some time. Mr Arorahad therefore suggested to the Bank to consider a covenant dealingwith the principle but providing for further discussion of animplementation timetable. While agreeing with Mr Wiehen that itwould be preferable if all issues could be solved before Boardpresentation, he hoped that the Bank could proceed on this basissince, given the importance and long history of the project, furtherdelays would have undesirable effects. He hoped the project couldbe negotiated soon, so as to make it possible to schedule Boardpresentation before the end of FY82 should additional funds becomeavailable. Mr Wiehen said that having not been present during thediscussions in Washington, he did not wish to comment at this stagebut would follow up on his return to Headquarters.
- Kallada Irrigation. Negotiations completed. Project now scheduledfor Board presentation in the last quarter of FY82.
, Gujarat Water Supply. Mr Arora anticipated no difficulty since inhis view, the State Government had replied to the Bank by submittinga proposal amounting to a doubling of the current tariffs. The StateGovernment had also agreed to the principle of recovering not only
Files 2. March 16, 1982
O&M but also some depreciation. Mr Arora hoped that thisproject could also be processed in such a way as to have Boardpresentation before the end of FY82.
Krishna-Godavari Exploration. Mr Arora said that he did notanticipate any major issue and urged Mr Wiehen to see if processingcould also be advanced so as to make Board presentation possiblebefore the end of the fiscal year should additional funds and aBoard slot become available. In reply to a question by Mr Wiehen,he said that India was determined to initiate a second round ofbidding for exploration as soon as the contract with Chevron wasfinalized, hopefully in a couple of weeks. He was hoping thatthe Bank would be willing to negotiate the project and submit itto the Board before the second round of bidding was actuallylaunched.
- Railways. The report of the Government mission that had visitedcomputer installations abroad was expected to be submitted by mid-April whereupon a program of action would be firmed up followinginterministerial discussions. This should make it possible for theBank to send its updating mission to India towards the end ofApril.
- South Bassein Gas Development. A Bank mission was currently inIndia to seek additional information on gas utilization. While heanticipated no major issue, Mr Arora commented on the time thefinalization of the'report was taking. Mr Wiehen replied that thegreater part of the delays had been due to the time it had takenfor Government to reach a final decision on the landfall. In replyto a further comment by Mr Wiehen, Mr Arora said that timing wasnow becoming a critical issue to ensure that gas would be availablewhen the Hazira Fertilizer plant was ready to come on stream.According to the current construction schedules for both projects,it looked as if there might be a time lag of about 3months.
- Haryana and J&K Social Forestry. Appraisal reporticurrently beingprepared. No major issue currently anticipated.
- Power Transmission V. Preappraisal scheduled for April.
- Nhava Sheva Port. Bank preappraisal mission currently in India.
- Calcutta Urban. Project currently being preappraised.
- Upper Indravati Power. Progress of preparation extremely slow.Mr Arora said he was extremely concerned about this and would doall he could to speed up the process.
- Subernarekha Irrigation. Appraisal report being prepared. Nomajor issue currently expected.
Files 3. March 16, 1982
- Chambal MP. Project deferred by at least a year for lackof local funds. Mr Arora used this opportunity to say thatto avoid delays due to lack of funds GOI had decided that inthe future, projects would only be submitted to the Bank whenavailability of local resources was fully assured.
Chambal Rajasthan. Appraisal report under preparation. UnlikeChambal MP, Mr Arora did not expect major problems.
- Haryana Irrigation. Project preparation seemed to be proceedingwell.but Mr Arora said he was concerned by what he understood tobe the Bank's intention not to include water supply and rural roadscomponents in the next operation. In GOI's view, the ongoingproject was an excellent example of a successful integrated ruraldevelopment approach. While the scope and relative size ofthe individual components could be discussed during appraisal andnegotiations, he felt the Bank should not a priori decide toexclude what had turned out to be viable components and wonderedif this reflected the Bank's internal administrative organization.Mr Wiehen undertook to look into it on his return to Washington.
- U.P. Tubewells II. The project would be reviewed in Delhi thiscoming week. Mr Arora drew Mr Wiehen's attention to what mightpossibly become a major issue insofar as he had been told during hisvisit to Washington that the Bank was considering seeking acommitment from U.P. that all future public tubewells in the Statewould be constructed according to the standards agreed for theongoing project. This, in Mr Arora's view might not be acceptablesince Bank-assisted tubewells were about twice as expensive asconventional tubewells. Such a commitment would presumably compelthe state to cut its tubewell construction program by as muchas half which, given the pressing demand for irrigation water, wouldnot be acceptable. Mr Arora also noted that IFAD had expressed thewish to participate in the financing of the project.
- A few additional projects e.g. Bihar Water Supply, Coal, andpossibly Cement, were at various stages of consideration/preparationand would possibly be submitted to the Bank in due course.
Commenting on the program in general., Mr Wiehen welcomed the stepstaken by GOI to speed up project preparation but expressed concern thatquite a few operations did not appear very firm at this stage. Mr Arorathought that apart from the Upper Indravati Power Project which was indeeda cause of serious concern, the problem seemed to affect essentially theirrigation sector. Mr Arora commented that future developments in agriculturewere bound to focus on the Gangetic plain and felt that the Bank's reluctanceto assist projects in that area would necessarily affect its overall lendingfor irrigation. Mr Wiehen replied that as GOI well knew, the issue was notproject related but mflected the international aspects of the Ganga basindevelopment which, as an international institution, the Bank could not ignore.

FROM: Karl G$ echoutek, Economist.' ASPEW
SUBJECT: INDIA - UP Tubewells Projects (I and II)Water Charges and Electricity Tariffs
1. In response to a memorandum to files from Mr. R.B. Reidinger,summarizing a discussion on the above issues on January 21, 1982, wewould like to communicate to you our concerns about some of the conclusionsand recommendations voiced in the memo. These concerns are mainly relatedto the cost of providing electricity to public tubewells and the structureand level of the tariff, including, in particular, the proposed applicationof a flat-rate tariff.
2. The operation characteristics of public tubewells are stated tobe based on standards (para. 9 of the memo) that would presumably allowaccurate estimation of the correct level of a flat-rate tariff. It is notclear how consistent the actual operation pattern 1(ignoring exogenousinfluences such as erratic power supply) would be over time to make a flat-ratetariff and a unit tariff equally desirable. Metering should be done in anycase, to gauge levels of consumption for purposes of setting the flat ratetariff level.
3. The marginal cost of electricity supply of Rs. 0.75/kWh (para. 10)refers to average marginal cost to a typical rural area as a whole at the33/11 kV substation. It excludes the cost of 11 kV lines to 11 kV consumers,and the technical losses incurred in this transmission. If public tubewellsare supplied at 11 kV, these costs should be added. In addition, if thereare public tubewells supplied at low voltage, the marginal cost increasesagain (to about-Rs 1.0/kWh and above in 1982 prices). Similarly, the shareof public tubewell power consumption during and off the system peak is relevant.Predominant off-peak use of public tubewells would reduce marginal cost belowthe average,significant peak-time use would increase it.
4. Present tariff levels at Rs. 450/HP/year are equivalent to aboutRs. 0.15 - 0.30/kWh (para. 12), well below acceptable levels that would be
.required to recover the cost of power system expansion. It also has to beborne in mind that the "accounting cost" (Rs. 0.24/kwh) as calculated by theSEB is based on historically-anlued assets and does not provide a usefulindication of necessary cost recovery during expansion. Both the presenttariff and the SEB financial cost, therefore, do not present desirablealternatives for pricing.
5. The incentive to operate tubewells at high rates of capacityutilization (paras. 18 and 20a) is assumed to be provided by a flat-ratetariff. This appears to conflict with the findings of the technical note(para. 6 of Appendix 1) that there is no motivation on the part of ID tooperate efficiently. If it is doubtful that the maintenance of the flat-ratetariff will provide a significant incentive, other considerations would indicatethat this tariff type should be opposed. In general, a flat-rate tariff ismuch inferior to a metered unit tariff, unless a very strong case can bemade t6 demonstrate the opposite. As not most (para. 21) but only a minorityof SEBs have moved over to a flat rate tariff for irrigation pumping, every
Mr. Gabriel J. Tibor, Chief, ASPAC - 2 - March 15, 1982
through F.H. Lamson-Scribner, Chief, ASPEW
effort should be made to nip the trend in the bud (para. 6.10 of proposed
Third RE Project appraisal report).
6. In Uttar Pradesh, it will be necessary to reconcile the requirement
for high rates of pump capacity utilization with the need to ensure that
public tubewell use during system peak hours is discouraged as strongly as
possible. Appropriate regulations or cutting of feeders at peak times should be
considered.
7. It is not clear why the level of the public tubewell tariff
should be equal to that charged an industrial user (para. 20b). The pattern of
electricity consumption may be quite different. Seasonality and peak/off-peak
consumption should be considered.
8. We suggest that undertakings be sought from the Government of
Uttar Pradesh in the course of project processing, that public tubewells
be charged at a metered tariff per unit of consumption (at a unit rate
significantly above present unit rate equivalents), and that appropriate
measures be taken to prevent use of the pumps at system peak times by shifting
their operation off the peak. Successful limitation to off-peak periods would
enable the SEB to keep the tariff increase within reasonable limits.

FROM: Mr. Leslie Abb B
SUBJECT: INDIA - U.P. Public Tubewells II Project
1. As you know, one of the subjects discussed at last Friday'smeeting (3/5/82) on the above project was the relative profitabilityof public and private tubewell irrigation in India. Apart from itsrelevance to the project, there is particular interest in this issueat present since the imminent 1982 Economic Report deals with it, alongwith many other topics, in a chapter on investment efficiency inirrigation. While not yet final, it is apparent that there is considerabledisagreement within South Asia region about the content and, moreimportant, the tone and possible operational implications of the 'public/private' analysis in the Report. The purpose of this memo is to restatethe main elements of the analysis in the Economic Report and hopefully toresolve any misunderstandings about its conclusions.
2. Study of the economics of private groundwater irrigation leadsto one inescapable conclusion -- that it is highly profitable by anystandards. Rapid development in the 1960s and 1970s, particularly in thenorth-west, is evidence in itself that it is financially attractive tofarmers. It is possible that this growth has been achieved at a highcost to the economy, through expensive subsidies. The existence ofsubsidies on power tariffs and connection costs cannot be denied. Yetthe evidence does not support the case that private gain has been achievedat unjustifiable public expense. Documentation from a long series ofARDC/World Bank Credit Project Completion Reports, as well as variousprivate studies, demonstrates that returns to the economy are comparablewith returns to the farmer.
3. Of course, the fact that private tubewell irrigation is highlyprofitable does not mean that there are no inefficiencies in its operation.Flat rate power tariffs, now introduced in some states including UttarPradesh, and the tendency to "overpower" engines (often for good reason)are disincentives to the efficient use of water and equipment. On the oftherhand many farmers are still either paying for electricity by the meter orusing diesel for which there is no subsidy. In either of these cases,and particularly the latter, there are strong incentives for efficientwater use.
4. Since their inception in the 1930s public tubewells have oftenbeen seen as the solution to problems for which private wells could provideno answer. In particular, the high capital cost of private wells inrelation to the size distribution of land holdings in the north-east hasbeen cited as a disadvantage which could be overcome by the cost advantagesand scale economies of deep tubewells. Also in many areas shallowacquifers for private development are either lacking or unsuitable. Inthese circumstances, the potential advantages of the public tubewell areindeed formidable. This is shown by the fact that existing "old style"public tubewells, despite their very low capacity utilization (often lessthan 50%), poor maintenance, and frequent power shortages, can still extract
-2-
water at a cost (Rs 0.3/m3 ) roughly comparable with that of the averageprivate shallow tubewell. If private wells are as inefficient as someclaim, then this is indeed an indictment of public well performance giventheir built-in advantages.
5. On the basis of past performance, it thus appears that theinefficiencies of public tubewells have cancelled out their potentialcost advantages. Turning to water use efficiency, comparison of thetwo systems presents an uncertain picture. For public tubewells, wherewater is charged on a volumetric basis (and where indeed the veryshortages caused by poor performance may induce more careful use ofwater) it is arguable, though certainly not conclusive, that the resultantincentives for efficient water use more than outweigh the known heavylosses of water in the old distribution systems. Comparing this possibleoutcome in States, such as UP, where private well owners pay forelectricity on a flat rate basis, it is clear that the balance may befavorably tipped towards public tubewells on efficiency grounds. Howeverthis is not inevitable. Moreover such a conclusion is almost certainlyreversed in other states where electricity is metered (and/or diesel ismore widely used), water is charged on an area basis, and distributionlosses are significant. In the absence of adequate data the best thatcan be said is that there is no clear answer.
6. Comparison of the effective cost of water under the public andprivate systems is inconclusive. However, if one compares the benefitsobtained from the use of water and complementary inputs under the twosystems, it is difficult to escape the conclusion that the advantage lieswith private tubewells. There are many estimated ex post rates of returnto private irrigation. Unfortunately those for public tubewells are extremelyscarce. Nevertheless a combination of field data (albeit limited) andcommon observation supports the view that the benefits of private tubewellsexceed those of traditional public tubewells. One of the few comparativestudies of well irrigation in U.P. in the late 1960s 1/ indicates thatcropping intensities and yield levels are higher, and shifts to higher-yielding/higher-value crops stronger under private than public irrigation.The public irrigation system inHaryana, widely agreed to be one of India'smost efficient and surely more efficient than public tubewells in thatstate, compares most unfavorably with private tubewells -- in terms ofshifts to high value crops, use of modern inputs, and yield levels. 2/Moreover, both water use efficiency and net returns per unit of water applied
were higher for private than public irrigation. Further support for theseconclusions is offered by the commonly observed phenomenon of private wellsin the command areas of public irrigation systems -- both surface andgroundwater. As has been pointed out, the evidence does not support the ideathat this is due to heavy subsidization.

7. The evidence above, in conjunction with the widespreadagreement about the problems of managing public tubewells, suggestsa single, dominant reason for the observed preference for privateirrigation among farmers. This is the independence, control, andflexibility which private ownership allows, and which, for a varietyof reasons, public tubewells have manifestly failed to provide. Theadvantages of these features for profitable cultivation of high-yieldingcrops are well-known and need not be discussed here. Suffice it tosay that for farmers the advantages of controlled and flexible watersupplies clearly outweigh the potentially higher costs of privateextraction; in practice, due to poor public tubewell performance,not even this cost disadvantage appears to have played a role.
8. What are the operational implications of all this, and, inparticular, what bearing does it have for phase II of the project?My feeling is that a comparative analysis such as this has someusefulness, the limits of which ought to be clearly recognized. Itsuggests, for instance, that over 30 years of accumulated experiencein public and private irrigation are to be ignored only at considerablerisk. This in turn indicates that if we are to err from a balancedassessment of the newly designed public tubewells, it ought to be onthe side of caution. There seems to be no doubt that the technologyintroduced under phase I is workable. What is not yet clear is thatthese technical improvements will feed through into a real economicgain for the farmers. A related, and important, question, is how farthe undisputed operational problems of the old tubewells are amenableto technological change alone. Although there may be good reason tobelieve that the corner has been turned, there is simply no hard evidenceavailable as yet to confirm this view. When considered in conjunctionwith the long record of past failure in public tubewells, there seem tobe compelling reasons for a more cautious approach than is currentlybeing proposed.
9. In my opinion, the above argument is about as much as one canusefully squeeze out of the analysis of comparative profitability.It is as misleading to use past performance as a tool for promotingprivate at the expense of public irrigation, as it is to use theunexploited potential of public tubewells to achieve the opposite resultObviously, it is incumbent on the Indians, with the assistance of theBank if possible, to exploit the potential cost advantages of publictubewells. At the same time nobody is going to stop farmers investing intheir own irrigation facilities if it is profitable. Since it is alsoprofitable for the country, there is no reason why it should not beencouraged. In truth, the notion that public and private irrigation arecompetitive has extremely limited validity at present. For technicalreasons, private irrigation is not possible in many areas. Moreimportant, unexploited groundwater potential in the north and north-eastis so vast, that there is a role for both methods, provided they arereasonably efficient. The relatively short economic life of privateirrigation equipment ensures adequate scope for the future substitutionof public tubewells should efficient solutions to their problemseventually be found.

The following notes summarize mission action with regard to theabove projects, and discuss certain project features which may beof general interest.
UP Tubewells II, and Bhairawa Lumbini Tubewells II
The two are discussed jointly, as the UP II technology is likelyto be adopted in Bhairawa Lumbini II. The system may also be relevantto tubewell projects in other areas, under consideration by InvestmentCentre staff.
UP Tubewells II, currently in an advanced stage of preparation,will employ the same buried pipe loop system (PVC) as was introducedin UP I project. It is particularly appropriate to situations in whichnon-paddy field crops are to be grown for part of the year. Thedesirable rate of delivery to the farm for irrigation of such crops isusually in the range 0.5 to 1.0 cfs (taken as 0.75 cfs for the purposeof this discussion). In the UP I system the discharge of the tubewellis divided into two to four equal streams each of 0.75 ofs (correspondingto well capacities of 1.5 to 3 cfs). Each stream supplies an individualpipe loop, with valved outlets at intervals along its length. In normaloperation one valve is opened at a time in each loop, delivering the whole0.75 ofs to its service area. The latter is usually of 3 to 5 ha, dependingupon the number of valved outlets provided and other factors. Conveyancefrom a valved outlet to the individual farm or field is by small unlinedfield channel, a distance generally less than 100 m. Moveable "lay-flat"roll-up plastic pipe, or hose, may also be used for conveyance over thislast 100 m. The valved outlets in each loop operate in turn, rotationally.
The advantage of the loop system is that flow to the valved outletin operation at any particular time is around both sides of the loop,effectively about one-half of the 0.75 cfs flowing in either direction.Required pipe size is thus reduced, compared with other types of layout.Further, the loop usually gives convenient coverage of its service area,from the viewpoint of location of valved outlets. The pipe in use for theloop systems in UP is generally 160 mm dia (6" I.D) PVC. The price ofPVC resin has remained nearly level during the last three years, duringwhich time the cost of other pipe materials, also channel linin materials,has increased by more than 30%. Price of 160 mm 2.5 kg PVC pipe,delivered, is approximately $3.85 per metre, and installed (in India)approximately $4.8 per metre.
The hydraulic control system at the tubewell (a reinforced brickworkdistribution chamber some 3 m in height, with float-actuated valve on thewell delivery line and level-sensing probes) provides the followingfunctions entirely automatically:
- Equal division of flow to all loops regardless of relativelocation and elevation of valved outlets in use.
- Throttling of well-delivery if irrigation from one of theloops ceases, but continues from the other (or others, ifmore than two loops).
- Shut-down of well if irrigation ceases from all loops.
- Start-up of well if irrigation resumes from any of thelOps.
The cost of the complete installation (in India) including tubewell,11 KV power connection, and pipe distribution system, at current pricelevels (based on actual UP I costs) is equivalent to approximatelyUS$550/ha. The cost of the pipe distribution system and controls only(i.e. excluding the tubewell and power connection) is approximately$360/ha.
The advantages of the buried-pipe system, compared with open channeldistribution from the tubewell, include the following:
(a) Higher delivery efficiency.
(b) Higher confidence level in delivery, on the partof the cultivator.
(0) Delivery much closer to the individual farm or fieldthan is practical with an open-channel distributionsystem.
(d) Elimination of problems of right-of-way and interferencewith farm access, inherent with open channels.
(e) Instant response to changes in demand, and to resumptionof power supply after an interruption.
(f) Much reduced maintenance.
(g) Less skill required in layout and construction of installationthan with open channel systems, and greater speed.
-h) Less cost per unit of water delivered.
While emphasising the technical advantages of the buried pipedistribution system it is nevertheless noted that a reliable supply ofwater is not alone sufficient to ensure that irrigation is taken uprapidly in a service area. Eperience with the UP I project has under-lined the need for project extension, in this case a demonstration plotpreferably in each tubewell command.
An essential feature of an electrically operated public tubewellsystem is a reasonably assured power supply. This is to be ensured inUP II (and retroactively to UP I) by the use of special 11 KV feeder linesexclusively serving groups of the project wells from 33 KV sub-stationsnominally not subject to power rationing. It is accepted, however, thateven where uninterrupted power is available tubewell operation shouldavoid hours of peak demand on the public power system, and should bedesigned around some 16 to 18 hours per day of power supply. Further,regardless of Government assurances that a line will not be subject tounscheduled outages these will almost certainly occur in Asian conditions

of chronic power deficiency, and the tubewell system should be designedto accommodate random interruptions without serious disruption ofwater distribution. As noted earlier, the buried pipe system hasconsiderable advantage in instantaneous resumption of delivery of waterat outlets on resumption of power supply.
The Bhairawa Lumbini II project is of interest in that a changeto a buried pipe distribution system is under consideration followingevaluation of an open, largely unlined, channel system employed in thecurrent Bhairawa Lumbini I. Reasons for the change are likelyto include the right-of-way and access problems encountered in Stage I(including the expense of road crossings over open channels), thedifficulty anticipated in water distribution within the nominally 8 haareas served by turnouts from the main channel (particularly in thecircumstances of a paddy-non paddy rotation), and finally the liklihoodof deterioration of open channels through anticipated inadequatemaintenance. Initial estimates indicate lower costs for the pipe systemthan for the o en channel, at present unit rates for materials (PVC,cement, bricks and labour.
Adequacy of power supply will be a consideration in the decisionwhether to proceed with the second-stage project at this time.
Kallada Project (Kerala)
This project, now in course of loan negotiation, will be the firstin India to employ a buried pipe field distribution system supplied froman open minor canal. The system has been developed with CP technicalassistance over the last year. It is described in the CP letter ofFebruary 18 '82 to GOK attached to memo of March 3 to X. Fenn (appendedto Bank and Management copies of this report ).
The factors which distinguish the Kallada system from UP II andthe proposed Bhairawa Lumbini II systems, which also employ buried pipe,are the following:
- The much smaller desirable delivery rate to the individual plotin the case of Kallada. The plot frequently is the basin arounda single coconut palm.
- The need to bring pipe delivery right to the plot at Kallada,as the area is under mature orchard crops planted for rainfedculture, rendering land shaping for irrigation distributionimpractical.
These two circumstances have led to adoption of a moveable hose(50 mm dia) delivering some 2.5 litres/sec or 0.10 cfs as the lastelement in the distribution system. The hoses are approximately 50 min length, and are supplied from valved outlets from a buried 90 mmor 110 mm pipe (or pipes). The outlet command served by each pipesystem is up to 10 ha, generally with slopes of 2% or more although 1% slopemay also be accommodated. During periods of peak demand four hoses are
in operation simultaneously. The maximum rate of flow to thecommand is controlled by a regulating valve at the intake (a one-time adjustment). The discharge at the various outlets on the buriedpipe system is not automatically uniform as in the case of the UP IItype of system, but an adequate degree of equality in delivery isobtainable by calibration of outlets and adjustment of delivery timesaccordingly. Flow regulating valves may be added at outlets as a laterrefinement.
It is noted that buried pipe systems for irrigation of conventionalfield crops (and paddy) in slopes of 1% or more are under considerationby CP for Subernarekha and Damanganga projects. The current veryfavourable price of PVC is likely to render pipe tertiary or quaternarysystems much more attractive than in the past.
Subernarekha Pro ject
The project is in course of appraisal. Issues considered duringthe mission are discussed in an attachment to the memo of March 3referred to above.
Karnataka Minor Tanks
At Bank request the mission initiated a training programme forstaff engaged on design of minor tank projects, particularly layout ofdistribution systems. The lecture notes compiled during the courseof this four-day "workshop" will shortly be distributed to Investment Centreengineers. Further action will include a ten-day visit to specific minorschemes in April and assistance to the State in preparation of additionaltraining material and setting in motion an in-service training programme.
Pro ject Pipeline
The India irrigation project pipeline was reviewed in Bank (GOIdiscussions in January). It is understood that Minor Tank projects willbe taken up for appraisal in Maharashtra and Gujarat in fiscal '83 - '84,and probably Rengali (Orissa). Activity on Upper Ganga Modernization(UP) is also likely to resume this year. The IFAD programme is understood(informal advice) to include co-financing of UP Tubewells II, followedby Minor Tanks Orissa, the latter for calendar '83.
- Shut-down of well if irrigation ceases from all loops.
- Start--up of well if irrigation resumes from any of theloops*
The cost of the complete installation (in India) including tubewell,11 KV power connection, and pipe distribution system, at current pricelevels (based on actual UP I costs) is equivalent to approximatelyUS$550/4a. The cost of the pipe distribution system and controls only(i.e. excluding the tubewell and power connection) is approximately$36OAa.
The advantages of the buried-pipe system, compared with open channeldistribution from the tubewell, include the following:
(a) Higher delivery efficiency.
(b) Higher confidence level in delivery, on the partof the cultivator.
(c) Delivery much closer to the individual farm or fieldthan is practical with an open-channel distributionsystem.

SUBJECT: INDIA - Briefing Note for UP Tubewells II Project
Performance of Existing Public Tubewells
1. Existing public tubewell (PTW) programs have generally beendisappointing because, almost without exception, benefits fall far shortof those estimated at appraisals. The basic defect is that they fail toprovide the irrigation service on which the estimates were based. Usersreact to unreliable irrigation service by not taking the financial risksnecessary to achieve agricultural production which is possible as a resultof good irrigation service. The three main reasons for the shortfall inbenefits are:
(i) unreliable power supply - most PTWs assume a regular powersupply of 16 hrs/day at peak demand. As power distributionlines are overloaded, power outages are not only the resultof rostering at the substations, but also as a result offluctuating voltage. (Our solution - dedicated powerlines);
(ii) inefficient distribution systems - present systems displayall the inefficiencies associated with the minor channels ina surface irrigation system except that in tubewells watersupply is severely limited and excessive conveyance lossescannot be tolerated (our solution - buried pipelinesdesigned in loops from the well points which enables thesystem to be operated automatically from the well pointand eliminates (hopefully) all conveyance losses); and
(iii) ineffective operation and naintenance - traditional PTWsdepend on the operator making management decisions; withlow pay scales, and with pressures from influential users,(large landholders near the well points) the operator hasa strong incentive tc manipulate the system, contributingcgreatly to the unreliability of service to nost of thecommand area.
2. Accountability for poor service with traditional PTWs becomesdifficult because 'down time' can be a combination of many of the abovedefects and compounded by the fact that project authorities generallyhave no incentive to provide the service promised to users. Whoever isaccountable can cloud the issue by laying the blame somewhere else!"No power", mechanical difficulties, misuse of water in conveyance bythe large upstream consumers, etc.
-2-
New Technology
3. UP Tubewells I has provided a technology that eliminates orminimizes the defects in existing PTWs. The new designs can provide(and be seen by the users to provide) a reliable irrigation service.There is little likelihood that these new designs will be much improvedin the foreseeable future. Because of the modularity of tubewelldevelopment (each well can be built separately and operated separately),a public tubewell project lends itself to staged construction, withbenefits dispersed over large areas and continuous improvement, (ifnecessary), in technology and operational procedures. There are nolumpy investments before benefits are generated. The basic issue is,
having demonstrated on a large enough scale that the new technology canresolve most of the problems of the traditional PTW design, what isthen the reason for a follow-up project?
4. A large scale follow-up project in our opinion is only
justified if important sectoral objectives can be achieved as a result
of the project. These sectoral objectives are mostly non-technical.
The arguments in favor of a large follow-up project l/ can be summarizedas follows:
(i) Because the new technology is considerably cheaper perunit of water delivered at the outlets than the traditionaldesigns and this fact is acknowledged by GOUP, any futuredevelopment in the public tubewell sector in UP must
logically follow the new designs. The financing ofadditional "new design" tubewells in UP if they are onlya fraction of the overall tubewell program of the Statedoes not make sense. One of the basic conditions of furtherIDA involvement must therefore be a commitment by GOUTP thatonly the new type of wells will be constructed in thefuture.
(ii) The size of the proposed project makes it essential forGOUP to reorganize its tubewell wing. We should thereforenegotiate a time-bound covenant (not more than one yearafter project effectiveness) for such a reorganizationto take place. Faiilg this, further disbursements shouldbe suspended.
1/ UP Government requested that the project construct about 4,300 new
public tubewells, modernize about 200 existing wells and connect an
additional 2,000 existing wells onto 'dedicated' power lines separate
from the existing rural grid, at an estimated cost of about $330 millionover a five year 'time-slice'.
-3-
(iii) A large scale, successful, public sector tubewell program
would provide a viable alternative to the rather inefficient
private tubewell program, with important social benefits
to the small farmers.
(iv) With a successful PTW technology, any shortfall in
agricultural benefits will be due to factors other than
the technical design of the PTI systems. This means that
we can address the issue of how to generate project benefits
separately from the shortfalls in the technical performance
of the water supply. _/
(v) The project scale will allow the concept of 'project
accountability' to be built into the project. Special
attention will be given at appraisal to monitoring,
evaluation and reporting activities to quantify 'accountability'of those involved in the project namely (a) the beneficiaries
and (b) the project authorities, each of whom has a role to
play in the achievement of the project objectives. We should
be able to build into UP II elements that provide the incentives
and minimize the risks which motivate users' response to the
project.
1/ The Bank involvement in irrigation projects is primarily in buildinginfrastructure to provide timely, reliable and equitable service;
using the service effectively and efficiently for agricultural
production is treated usually as a separate issue (T&V projects,
agricultural research etc).

SUBJECT: INDIA - UP Tubewells Projects (I and II)Water Charges and Electricity Tariffs
1. On January 21, 1982, Messrs. Rodger and Reidinger (ASPAC),Mr. Campbell (FAO/CP), and Messrs. Lamson-Scribner, Stichenwirth, andAntonescu (ASPEW) met to discuss electricity charges under the ongoingUP Tubewells Project and the proposed UP Tubewells II Project. FAO/CPthrough Mr. Campbell prepared the first project and is assisting prepara-tion of the second.
2. The specific question discussed at the meeting concerns whetherwater charges actually paid to farmers cover the real or economic costof electric power for pumping public tubewell water. A draft technicalnote prepared by Mr. Campbell, is attached (see Appendix 1) and comparespower and water charges for public tubewells. 1/. The following considetsthe question on the basis of Mr. Campbell's note and the results othe January 21 discussions.
Background
3. The first UP Tubewells Project financed about 500 public tubewellslocated throughout the State of UP. It introduced several key technicalinnovations dnsigned to raise the level of performance for publIctubewells, which is generally very low in UP. The proposed UP TubewellsII Project would follow-up on the first project, introducing these techni-cal improvements in some 4,300 new tubewells under the Project and upgrad-ing about 200 additional existing tubewells throughout the State.
Pricing for Efficiency and Cost Recovery
4. Two key issues relate to the question of power and water chargesunder the UP Tubewells Projects:
(a) Efficiency, which relates to the type or structure of chargesor tariffs and whether the charges prfomote or discourageefficient use of water and power resources; and
(b) Cost recovery, which refers to the actual level or totalreceipts of water charges and whether they pay the full orreal costs involved.
5. In general, pricing for efficiency of water or power use needs tobe based on per unit or volumetric prices (e.g., in Rs /m3 or Rs/1,000gal. of water, or Rs/kWh of power). In this way, the total cost paid bythe user reflects the actual amount of water or power used and per unit orvolumetric pricing generally encourages efficient and economical use ofwater or power. In contrast, flat rate charges (a Rs/acre irrigated watercharge, or a Rs/horsepower power charge) are not directly related to the
1/ The draft note was edited by John F. Cunningham, ASPAC.
-2-
actual amount of water and power and tend to promote their waste and
inefficient use. The use or "efficiency pricing" as a tool to promoteeconomic efficiency depends on the degree to which decision-making by
users is market (profit/loss) oriented, and of course, the actual level of
the per unit charges involved. Per unit and volumetric pricing impacts
directly on the costs and net returns of water and power users (e.g.
farmers) in determining the mix of resources they use.
6. Pricing for cost recovery is a different issue and may or may not
impact on economic efficiency, depending on the type of pricing system
employed. "Cost recovery" pricing has primarily a budgetary impact on
suppliers of water and power and by itself, may not necessarily affect
directly the day-to-day decisions by water and power users. Tariffs which
do not cover costs will be reflected in budget deficits (losses) by the
supplier. A private supplier would soon be forced out of business by such
losses, while in the public sector, government would have to make a
political decision on whether and how to make up the deficits and thus
subsidize the users. Cost recovery in the public sector is therefore a
highly political issue which by itself need not be related to efficient
water and power use by users, except when combined with per unit or
vlumetric ("efficiency") pricing.
Volumetric Water Charges Under UP Tubewells
7. Volumetric pricing is used for irrigation water from public
tubewells in UP. Farmers pay the UP Irrigation (ID) for their tubewell
water on a volumetric basis, according to the amount of water actually
used. This promotes efficiency in water use, and is unlike our otherirrigation projects in India where water charges are levied crop-wise onthe basis of irrigated area. Water charges based on irrigated area tend
to encourage waste of water, in contrast to volumetric charges.
Volumetric water charges have been considered important for efficiency
reasons (but generally ignored) at least since the first Indian Irrigation
Commission in 1901-03.
8. In addition, GOUP raised the charges paid by-farmers for public
tubewell water in July 1981 by 20 percent in the rabi season and 60
percent in kharif. UP farmers now pay for their tubewell water at the
rate of one Rupee for 5,000 gallons (Imperial) in the dry (rabi) season
and 10,000 gallons in the wet (kharif) season. GOUP raised tubewell water
charges largely on its own initiative. The State has thus been relativelyprogressive as concerns public tubewell charges, both in establishing
- volumetric (efficiency) pricing and in raising water charge rates.
Electric Power Charges for Tubewells
9. Electric power charges paid by ID to the State Electricity Board
(SEB), however, are not based on volumetric or "efficiency" pricing. The
-3-
power charge is based on a flat rate per horsepower (Rs 450/HP) annually,
not related to actual power used. SEB charges private tubewell farmers on
a similar basis. Under a market oriented situation (e.g., private
tubewells), such flat rate charges encourage inefficiency and waste of
power which is a serious problem in power-short UP. However, public
tubewells under the project are installed and operated by the government
on the basis of specified technical standards. Unit pricing for elec-
tricity would therefore probably have little impact on the efficiency of
tubewell operation in terms of electricity use for technical reasons. In
addition, evidence indicates government departments tend to be generally
unresponsive to direct cost and price market incentives in their day to
day operations,' as compared to the private sector.
Electricity Costs and Tariff Levels
10. Based on ASPEW data (see Annex 29 of the proposed third Rural
Electrification Project; pages 1 and.2 of Annex 29 are attached as Appen-
dix 2), the real "marginal" cost of electricity is about Rs 0.75/kWh. The
"accounting" (financial) cost based on GOUP data is Rs 0.24/kWh. Actual
"market" tariffs levied are at present Rs 0.50/kWh for domestic consumers
and Rs 0.41/kWh for industrial consumers.
11. Four different cases are relevant to the question of water charges
paid relative to power costs for public tubewells: the financial impact of
the present water and power tariff structure and rates based on the per
horsepower elctricity charge, and three alternative cases based on the
amount of power actually used with the levels of price for power based on
the accounting cost, market cost, and marginal cost of electricity sup-
plies. In addition, public tubewells can normally be expected to run
about 4,000 hours per year. New tubewells under the Bank project will
have "dedicated" power feeder line service and should be able to achieve
that level of operation. Under present power short conditions, most
public tubewells average about 2,000 hours of operation per year, and many
run significantly less than that. Two levels of running hours (4,000 and
2,000 hours) are therefore considered for each of the above four cases.
12. Present Financial Returns. ID charges farmers according to the
volume of water they use (see para 7). At the same time, ID pays SEB for
electric.power on a flat rate basis (see par 9). Financial results for a
typical tubewell assuming approximately average operating conditions (see
Appendix 1) are as follows:
4,000 hours 2,000 hours(Rs) (Rs)
Water charges to farmers a/ 24,000 12,000
Power costs to ID b/ 9,000 9,000
Net gain (loss) to ID 13,000 3,000
a/ Water charges are based on water use of 106 million
(imperial) gallons costing Rs 21,200 in the dry season,
plus 78 million gallons costing 2,800 in the wet season.
b/ Power costs based on 20 horsepower ar a rate of Rs 450/
horsepower annually.

13. With either 4,000 or 2,000 hours of operation annually, the water
charge actually paid by farmers to ID more than covers the cost of power
paid by ID to SEB. With 4,000 hours of operation, farmer payments to ID
for water fully cover financial operating costs (power costs, and also O&M
costs estimated at Rs 7,500 annually) plus a small additional contribution
to capital costs (actually an addition to ID budgetary resources). With
the lower 2,000 hour operating rate, farmer payments cover the electricity
costs and only part of O&M costs.
14. Under the present system of electricity and water tariffs, farmers
more than pay for the financial cost of power used. In addition, public
tubewells can be a budgetary asset to ID provided high operating rates
can be maintained (achieving high operating rates is a major purpose of
the improved tubewells under the IDA project). Financial incentives in
terms of ID budget resources encourage efficient operation of public
tubewells under the present tariff systems.
15. Accounting Cost Tariffs. Pricing electricity on a per kWh basis
at the "accounting cost" for power actually used would also yield for ID a
significant surplus of water charge payments over power costs, as shown
below. The surplus would be sufficient to cover 0&M at the 4,000 hour
operating rate, but not at the 2,000 hour operating rate.

a/ Assuming annual power use of 56,000 kWh for 4,000 hours
of operation (28,000 kWh for 2,000 hours) valued at an
accounting cost of Rs 0.24/kWh.
16. Market Tariffs Cost. Pricing electricity at present "market
cost" tariff rates for industrial users would result in a small surplus
for ID, as shown below. The surplus would not be sufficient to cover O&M
costs for either high or low tubewell operating rates.

However, a 30 percent increase in water charges at the high operating ratewould be more than sufficient to cover power costs valued at market tariff
rates plus O&M (full operating costs).
17. Marginal Cost Tariffs. With electricity priced at the "marginal"
cost for power, water charges paid by farmers would not cover electricity
costs, as shown below. Water charges would have to be raised by 75 per-
cent to cover electricity costs valued at the marginal cost of power, and
more than doubled to cover electricity valued at the marginal costs plus
O&M.

Net gain (loss) to ID (18,000) (9,000)
Summary and Conclusions
18. Under the present system of water charges and electricity tariffs,farmer more than pay the financial costs of electricity for tubewell
operation. In addition, the present system and structure of tariffs
provides ID with a substantial budgetary incentive to operate itstubewells efficiently with high rates of capacity utilization. Indeed,water charges current levels would be more than sufficient to cover power
costs based on a per kWh charge equivalent to the present market rates of
electricity tariffs for industrial users, which is nearly double the
"accounting" cost tariff for the power. But they would not cover O&Mcosts in addition.
19. Requiring farmer water charges to cover electricity costs valued
at the "marginal" cost of power tariff rate would require an increase of
about 75 percent in water charges, or an increase of over 100 percent to
cover tuil operating costs including O&M. Under the present system ot tiatrate electricity charges paid by ID to SEB, a higher water charge paid toID would simply increase ID budgetary resources while reducing net farmerincome. In addition, estimated marginal cost electricity tariffs areconsiderably higher than present market rate electricity tariffs chargedto industrial (and domestic) consumers. Charging small farmers for waterat a much higher rate (in equivalent electricity costs) than paid by largeindustrial users would be difficult to justify in terms of equity.However, a special service surcharge for water from project tubewells maybe justified, based on the improved irrigation service provided.
Recommendations
20. Based on the above discussions, the following approach to powertariffs and water charges for the UP Tubewells II Project appearsfeasible.
(a) SEB would continue to charge ID for electricity on thebasis of a flat rate tariff. Combined with the volumetricwater charge system now in operation, this will provideID with a budgetary incentive to maintain high operatingrates on project tubewells.
(b) The annual amount of the flat rate power tariff paid byID to SEB would be raised to insure that power chargespaid are equal to the charge which would be paid atmarket rates by an industrial user for the same amount ofpower as used by the "average"-tubewell.
(c) Volumetric water charges paid by farmers should be raisedsufficiently to cover the power charge in (b) above, plusO&M costs. This can be justified on the basis of theimproved service provided under project tubewells.
21. If justified on general policy and economic grounds, SEB couldgradually raise power tariffs for all users to reflect the "marginalcosts" of power, with corresponding adjustments in water charges. Forfarmers served by project tubewells, however, this may raise financialviability questions, since the price received for his produce isadministratively rather than market determined. In addition, most Statesin India have been moving toward flat rate (rather than per unit) pricingof electricity use in agriculture The level power tariffs and type of
pricing for electricity are serious issues which may be more effectivelydealt with in large IDA power projects, rather than a public tubewellproject where our leverage in the power sector is small.

INDIA
UP TUBEWELLS II PROJECT
Cost Recovery
1. In UP Tubewell I project, and currently proposed for UP TubewellII, charges are as follows:
(a) The Irrigation Department pays the State Electricity Boarda flat rate of Rs 450 per installed horsepower per annum(the same rate as for private well owners). It also paysthe capital cost of transformer and connection from the11 kv line (in UP II it will pay the additional cost ofthe "dedicated " 11 KV feeder from the 33 KV substationand where appropriate a portion of the cost of the sub-station if it has to be enlarged).
(b) The cultivator pays the Irrigation Department for water.The water charge in the wet season is lower than in theremainder of the year to encourage use of irrigation inthat season. The rates are as follows:
Current Rates Previous Rates(Since July 1, 1981)
Wet Season(16 April - 15 Oct) 10,000 Gals (Imp) 16,000 Gals
per Rupee per Rupee
Dry Season(16 Oct - 15 Apr) 5,000 Gals 6,000 Gals
per Rupee per Rupee
2. Comparison of water charges and actual costs of power to the S.E.B.and providing the irrigation service by Irrigation Department depends verymuch upon the hours pumped per year. Two cases are considered hereunder.The first case assumes a "dedicated power line" will insulate the publictubewells (PTWs) against rostering (load-shedding) *and thus the annualhours of pumping can be expected to reach about 4,000 hours. The secondcase assumes operation of PTWs of 2,000 hours per annum, which approximatesto the average of the last three or four years when power rationing hasbeen severe (in 1981/82 power availability has dropped in some parts of UPto 1,000 hours).
3. In the first case, the assumed hours of operation are describedas follows:
Dry Season 16 hrs/day for 197 days 3,152 hours
Wet Season 5 hrs/day for 168 days 840 hours
Total 3,992 hours
say rounded to 4,000 hours
In the second case the seasonal hours of operation were taken as one-halfof the above.
-2-
4. For estimation of power required, a typical PTW is assumed to
have the following characteristics:
Discharge 1.5 cfs (560 g.p.m. Imp)
Dynamic Head 20 m (66 ft)
Overall Efficiency (wire o 60%water)o
Power Required 14 kW
Installed Horsepower 20 HP
Energy consumed annually 56,000 kWh
(4,000 hrs pumping) -
Irrigation Supply: Dry Season 3,152 X 560 X 60 106 Million Gals
Wet Season 840 X 560 X 60 28 Million Gals
5. Costs of irrigation service and water charges paid by cultivator
are compared as follows:
A. With 4,000 hrs of pumping annually
Charge paid by.Irrigation Department to S.E.B. annually would be:
20 HP X 450 rps Rs 9,000
Irrigation Dept. O&M costs other than power (Est) Rs 7,500
Rs 16,500
- S.E.B. costs -
(a) At "accounting cost" of power: 56,000 X 0.24 Rs 13,400
(b) At "marginal cost" of power: 56,000 X 0.75 Rs 42,000
- Present water charges paid by cultivators served by PTWs would
be:
Dry Season 106 Mill Gals at 5,000 Gals/Rupee Rs 21,200
Wet Season 78 Mill Gals at 10,000 Gals/Rupee Rs 2,800
Total Annual Cost- Recovery Rs 24,000
B. With 2,000 hours of pumping annually
-.Charge paid by Irrigation Dept. to S.E.B. annually Rs 9,000
O&M Costs Rs 7,500
Total Operating Cost Rs 16,500
- S.E.B. costs:
(a) At "accounting cost"
Rs 0.24 X 28,000 kWh. Rs 6,700
(b) At "marginal cost"
Rs 0.75 X 28,000 kWh Rs 21,000
Present water charges paid by cultivators serviced by PTWs would be:
TOTAL Rs 12,000
Conclusions
6. The above analysis indicates:
(i) With 4,000 hrs of pumping annually, the water charges paid
by cultivators more than cover the operating costs of the
Irrigation Department, but make little contribution to
capital cost recovery (the cost of a typical PTW installation
to the UP Tubewell II design is approximately Rs 480,000).
(ii) With 2,000 hrs of pumping,the water charges paid by cultivators
do not cover Departmental operating costs but does cover the
ID cost of power at present rates set by SEB.
(iii) Under the present flat tariff rate for power, the Depart-
mental payment to the SEB barely covers the SEB costs at
"accounting" rates for power with 2,000 hrs of pumping.
If PTWs achieve the planned 4,000 hours of pumping per annum,
the Departmental payment to the SEB does not cover SEB costs
at "accounting" rates for power, and is less than 25% of SEB
costs at "marginal" rates.
It would seem that a flat rate charge for power to the Irrigation Department
should in theory, encourage them to maximize the operating hours of PTWs and
thus the returns to the PTW investment (a fundamental objective of the UP
Tubewell Projects). Alas, there is little evidence to show that IDs or a
government agency anywhere thinks and acts this way; they do not have the
incentives that motivate the private sector, namely the chance of going
bankrupt! The ID does not directly collect water charges to pay for O&M
costs; collection is through the Revenue Department. The O&M funds are
allocated to the ID through the general budget and are not conditional on
the performance of the ID. There is therefore no need or incentive within
the ID to relate O&M costs and recovery particularly as there is no real
'accountability' for quality of irrigation service. It is therefore concluded
that to link cost recovery from farmers to costs (direct and indirect) of
providing the irrigation service has no real impact on project performance.
Project benefits depend on the users of gr.oundwater believing that
the irrigation service is reliable and cheap enough for irrigated agriculture
to be financially viable with acceptable risks 1/. Power costs are a
small portion of the input costs necessary to achieve predicted agricultural
benefits to groundwater development. Furthermore, GOUP is commited to main-
taining a substantial use of power in the agricultural sector (about 34% of
power use). It is inconveivable politically to consider withdrawing this
service for cost recovery reasons. Therefore the issues with respect to
power tariffs become:
1/ At present in UP, the main risk perceived by users is the unreliable
Gervica provided by public tubewells.
-4-
(i) to decide whether it is politically expedient to
recover the power cost directly through water chargesor indirectly through general agricultural taxation;
(ii) what can be done to encourage the best economic returnper unit of power used in the agricultural sector (bothprivate and public sectors); and
(iii) how power use can be manipulated in the agriculturalsector to provide the best load characteristics forthe SEB.
Thus, in terms of project performance, the water charge appears to besimilar to any other tax on irrigated agriculture and Government hasto judge what level of this type of taxation is politically acceptableto farmers. What is needed is motivation to make the ID and Governmentprovide the promised service from a 'monopolistic' utility. Onepossibility is that 'accountability' could be achieved by compensatingusers for less than promised service on which the users have plannedand thus evaluated their financial risks.

4. BRIEF DESCRIPTION OF MAJOR OBJECTIVES AND KEY COMPONENTS:
The primary objectives of the proposed project are to continue and expand the public tubewelldevelopment under UP Tubewell I. The first phase project was a statewide program of about500 public tubewells (PTWs) designed to eliminate the major problems affecting PTWs in UP.The improved design provides for (i) automatic operation of the well; (ii) a buried distributisystem which enables irrigation service to be 'on-demand', and (iii) separate power lines toclusters of PTWs. UP Tubewell II would include 4,300 new PTW systems; improvements to 200(out of 18,000) existing PTWs; provision of connections from the separate power lines toabout 2,000 existing PTWs.

Project Officer: John F. Cunningham
A. Sectoral Context
1. India has a population of about 680 M which is growing at an
annual rate of about 1.9%. Since 1960, per capita income grew at an
annual rate of 1.4% and reached US$ in 1979/80. Although the average per
capita income has increased and access to public services has improved, in
general, there has been little change in the incomes of the. vast masses of
urban and rural poor, who comprise about 50% of the total population.
Accordingly, GOI's development plans give priority to alleviating poverty
and creating employment, especially in rural areas.
2. Agriculture is the dominant sector of the Indian economy and
contributes about 40% of GNP. It engages about 70% of the labor force and
provides the base for about 55% of India's exports. During the last
decade, GOI has devoted considerable attention to agriculture in its
development plans. To support agricultural growth, GOI has: (i)
accelerated irrigation development through modernization of existing
schemes and constructions of new schemes; and (ii) improved agricultural
supporting services to optimize the use of land and water resources.
3. Irrigation was given the highest priority from the beginning of
the planning era in 1950. Some 52.6 M ha were developed by 1979/80, about
58% of which is from surface sources and 42% from groundwater. Irrigated
areas are almost four times as productive as rainfed areas and they
account for about 60% of all agricultural output in India. Moro sig-
nificantly the expansion of irrigation facilities and the productivity
growth on irrigated lands have together accounted for at least
three-quarters of agricultural growth since 1960. The area developed for
irrigation is expected to grow to 66.2 M ha by the end of 1985/86, of
which 56% will be from surface sources and 44% from groundwater sources.
With little idle land left for cultivation, limited increase is expected
in the net sown area in the future and the main increase in agricultural
production will need to come from double cropping and from improvements
in
water management and in the use of agricultural inputs. In most completed
projects, the actual irrigated areas are less than planned and yields have
been much lower than the original forecast. GOI and the State Governments
are aware of the challenge and are seeking solutions to -the dual problem
of low irrigation intensities and poor yields. Solutions involve improved
-2-
efficiency of the physical system, more flexible and imaginative water
management practices and improvements in the supply of agricultural inputs.
(credit, extension, etc.).
IDA's Role in the Sector
4. A major constraint to a further increase in agricultural produc-
tion in the Northwestern States of India is the limited quantity of water
available for irrigation. Surface water resources are either fully
developed or committed and any further expansion of irrigated agriculture
can be achieved only by improving efficiencies and further development of
groundwater. An important element of GOI and the Bank's strategy has been
to promote increases in water conveyance efficiencies and the full
utilization of groundwater investment in the public sector.
Public Tubewells in UP
5. A detailed description of the State related to groundwater
development is given in the SAR of UP Tubewell I Project (Report No.
2758-IN, dated March 20, 1978). Construction of public tubewells (PTWs)
was initiated in 1931/32; by 1950, some 2,200 were in service, increasing
to 10,000 by 1970 and 18,000 by the end of 1981 with present rate of
construction reaching about 1,100 wells annuallyl/. In general, PTWs are
installed in areas not commanded by canals and where conditions are not
conducive to private tubewell development, i.e., where water table is too
deep for centrifugal pumps commonly used for private wells or in backward
areas where private development is unlikely to take place within a
reasonable time.
6. Annual operating hours serve as a useful performance indicator of
PTWs and during the last few years, operating hours averaged only about
1600 hours per well per year. To achieve design objectives and benefits
assumed in the project analysis, PTWs are expected to run annually about
4,000 hours. The poor performance of PTWs in UP is due to (a) power
shortages (availability during the peak season can be as low as 8 hotirs
per day compared to 16 hours per day assumed in design) and frequent
unpredictable power outages; (b) mechanical and electrical breakdowns and
delay in repairs; and (c) frequent absence of tubewell operators.
7. While annual operating hours are a useful indicator of tubewell
utilization, they are not the only factor. Other factors such as exces-
sive losses in the water distribution system, overly large command area
1/ About 250 tubewells to the improved designs under UP Tubewells I and
some 850 to the traditional design used before the Bank assisted
Project.
-3-
(600 acres) related to well capacity (1 to 5 cusecs), and unreliabledelivery particularly to cultivators distant from well points, contributeto lack of confidence in water supply from PTWs. The result has been thatcultivators are unwilling to risk the level of inputs necessary for satis-factory crop yields.
8. However, since groundwater is the easiest and most assured source
of irrigation that can be provided in the public sector and presentstatewide extraction is slightly less than 50% of total groundwaterresources, GOUP has attached a high priority to-development of both public
and private tubewells. IDA has participated in financing privatetubewells through ARDC credits. IDA also financed construction of 800
PTWs in UP from 1961 to 1964 (Cr. 8-IN, US$6 M). This first projectfailed to achieve its agricultural potential due to the reasons described
para 6 above.
UP Tubewells I Project
9. To assist UP to overcome the basic shortcomings in their PTWprogram, IDA supported a UP Tubewells I Project (Credit 1004-IN), which
was formulated as a two year program to test and demonstrate improvedtubewell technology. UP Tubewells I is due to be completed in August1982. The main technical improvements under UP Tubewell I Project were:-
(i) An elevated storage tank with hydraulic controls to
regulate discharge and enable the well point to operateautomatically and thus minimize operator interference;
(ii) A buried pipe distribution system with outlets commandingabout 3-4 ha to ensure timely, reliable and equitabledistribution;
(iii) Additional electrical equipments to protect the motorsagainst irregular voltage;
(iv) Tubewells clustered in groups on "dedicated" power linesl/ to
enable reliable power to be supplied to selected users;and
(v) Improvements in the organization of the Tubewell Wing of theIrrigation Department to manage and also to monitor and
evaluate the new design concept.
1/ This was rejected by UPSEB at appraisal but later agreed during the
project period once it was realized that without reliable power supply
UP Tubewell I could not achieve the assumed project. benefits.
-4-
The primary objective of UP Tubewells I Project was to test and evaluate
technical and organizational improvements over the traditional PTW design
on a pilot basis before COUP undertook a major investment in the new PTW
concept.
10. UP Tubewells I Project has substantially fulfilled this objective
and sufficient data has been collected and evaluated to enable a full
scale program to be supported with acceptable risk. In general, UP
Tubewells I has been implemented successfully and performance data from
completed works indicate that the improved PTW concept is a major improve-
ment over traditional UP designs.
11. The lessons learned from (and the consequences of) UP Tubewells I
which will be used in the follow-up project have been:-
(i) The full project benefits can only be realized if tubewells
are energized from "dedicated" power lines; this will enable
power supplies to be taken separately from the rural grid
thus enable design objectives of up to 16 hr/day operation
to be achieved;
(ii) The management performance of the Tubewell Wing with respect
to operation and maintenance provisions and monitoring and
evaluation activities has been poor. This is partly because
the IDA supported program was small compared to the other
State TW programs; the scale of UP Tubewells II is such that
leverage can be used to make GOUP undertake necessary
management changes in the ID (see para 14);
(iii) COUP should endorse the improved tubewell technology for
all new PTWs throughout the State and make the necessary
organizational provisions for this to be possible 1/; and
(iv) COUP needs to give more attention to cost recovery in
the public tubewell sector (see para 19).
1/ At present, under the ARDC general line of credit, the Bank is
indirectly supporting a program of 750 new PTWs through UP Tubewells
Corporation formulated to the traditional PTW design standards which
are now obsolute.

Project Formulation & Preparatio"
12. The preparation of UP Tubewell II project has been carried out by
the technical departments of GOUP with the support of IDA consultants. A
draft preparation report and various technical notes have been prepared
through 1981. This work has been updated as performance data from UP
Tubewells I project has become available and after discussions with GOUP
during a preparation mission which visited UP in January 1982. The scope
of the proposed UP Tubewells II has been cleared by GOI and consideration
has been given to transition requirements from UP Tubewells I so that the
existing implementation momentum is not lost. The preparation reports and
supporting data being made available to IDA will provide an adequate basis
for appraisal.
C. The Project
Project Description
13. The Project is intended to cover a five years' time slice
(1983-88) of the GOUP development in the PTW sector. It would include
about 4300 PTWs based on the improved design with buried pipe distribution
systems. The project also provides for modernization of about 200 exist-
ing PTWs with the objective of (i) increasing annual operating hours of
these wells and (ii) improvements to the timelines, reliability and equi-
tability of the irrigation service. The new PTWs will be grouped in
clusters of 10 to 15 supplied by a power line which will be separate from
the existing rural grid. Each "dedicated" power line will also provide
connections to existing PTWs within reasonable distance of the connector
(say up to 2 km). In this way, it is estimated that about 2000 existing
PTWs will be provided with reliable power supply under the project.
14. In addition to works to be constructed, the project would enable
basic organizational charges to take place within the Irrigation Depart-
ment. At present, the Tubewell Wing (TW) is organized such that construc-
tion, and operation and maintenance are administered by the same units
with most resources devoted to construction. The TW is also divided s3
that one part constructs and operates PTWs of the traditional design while
separate circles deal with those PTWs constructed under UP Tubewells I
Project. It is proposed that a complete reorganization of the TW takes
place to form separate units dealing with old and new technology. More
important is that proposed GOUP constructs only PTWs to the improved
design. Details of these organizational changes will be decided at
appraisal and an organizational schedule will be prepared and agreed with
GOUP as part of the project agreement.

Project Impact
15. The 4500 new and improved PTWs under the project will bring about
0.5 million ha under irrigation; use of the "dedicated" power lines should
enable a further 0.2 million ha presently irrigated by existing PTWs to
have an improved service based on a reliable power supply.
Conclusions and Recommendations
16. Impact of UP Tubewells I Project. The first phase project was
formulated as a pilot demonstration to test the improved PTW technology
on a large enough scale to identify possible implementation and organiza-
tional constraints. The two year program under UP Tubewells I has
provided sufficient evidence that a major investment by GOUP in the new
technology is justified. The project is likely to overcome most of
shortcomings which restrict traditional PTWs achieving (i) predicted
agricultural benefits and (ii) providing a timely, reliable and equitable
irrigation service. It is concluded from data made available by GOUP that
it is unlikely that the design concept of the new PTW technology can be
basically improved within forseeable planning horizons. It is also con-
cluded that the risks of not achieving agricultural benefits because of
technical shortcomings in well design are small. Furthermore, the nature
of a PTW project is such that if changes in design are considered
expedient, they can be introduced at any state of the implementation
program. UP Tubewells I project has confirmed that the traditional PTW
design used by GOUP outside the IDA supported project is obsolete. As
GOUP plans to construct at least 1000 new PTWs annually, there seems to be
little merit in delaying UP Tubewells II project until PTWs completed
under UP Tubewell- I achieve full predicted benefits.
Leverage of UP Tubewell TI Project
17. If IDA supports UP Tubewell II Project as formulated, the "time
slice" will include most of the PTWs to be constructed under the state
planned budget over the next five years. GOUP should endorse the new
design for all future PTvs to be installed in the State and make the
necessary organizational changes to implement such a decision.
18. Extension. Preliminary data on performance of UP Tubewell I
project indicate that farmers are not taking up irrigation as quickly as
would be expected given that most impact areas are presently rainfed
agriculture. In theory, the command area of PTW can be provided with a
reliable irrigation service immediately a well is commissioned. The
appraisal will evaluate what can be done to reduce the time taken to build
up to full benefits and efficient utilization of the new PTWs.
19. Cost Recovery. Insufficient attention has been given to cost
recovery from PTWs during UP Tubewell I primarily because the project was
a pilot and the new PTWs formed a small proportion of total number of PTWs
in the State. However, through UP Tubewell II, GOUP will commit itself to
eventually changing all PTWs in the State to a design where water can be
charged on a volumetric basis. Clearly farmers will want to pay as little
as they can and pressure Government accordingly in the knowledge that
water charges are a sensitive, political issue. Evidence to date indi-
cates improved PTWs under the first phase project do encourage (and
enable) efficient use of water because the design makes it only possible
to operate the systems efficiently. It seems that when water is scarce
but the irrigation service is reliable, farmers are more concerned with
water availability rather than cost. It also seems that once a reliable
service is provided, with a system that distributes supplies equitably,
the effect of volumetric water charges on efficient water use is likely to
be neutral. What farmers can be made to pay then, depends on how they
value the water and above all, they judge the ability of Government to
enforce a higher water charge. It is also clear that once a reliable
irrigation service is provided, unless maintenance is extremely poor, the
service cannot be withdrawn. O&M funds for PTWs are not directly depend-
ent on cost recovery and the State's has accepted the principle of subsidy
for minor irrigation. It is therefore concluded that although water
charges are low compared to incremental benefits to reliable irrigation,
farmers response to any increase in water charges is not going to be
predictable or logical but political. Government has to decide water
charges on what it considers to be appropriate and fair and more impor-
tant, is willing to enforce. Issues which may be considered in setting a
"bottom line" on cost recovery are (i) whether water charges actually paid
by the farmers should cover the real or economic cost of electrical power
for pumping; (ii) the basis for calculating'the water charges; and (iii)
whether water charges for the new and old PTWs should reflect the quality
of irrigation service.
20. The responsibility of project authorities (and the Bank) is to
inform Government of the actual cost of effective operation and preventa-
tive maintenance so that PTWs can achieve predicted banefits. This May
mean that the accounting and audit procedures of the ID should be such
that the actual (and economic) costs of O&M can be separated from con-
struction costs. The Government responsibility is to decide what cost
recovery level. can be achieved without having a detrimental affect on
farmer attitude and thus project benefits.

OFFICE MEMORANDUMTO: Files DATE: March 4, 1982
FROM: Richard B. Reidinger, Senior Agricultural Economist, ASPAC
SUBJECT: INDIA - UP Tubewells Projects (I and II)
Water Charges and Electricity Tar-iffs
i. On January 21, 1982, Messrs. Rodger and Reidinger (ASPAC),
Mr. Campbell (FAO/CP), and Messrs. Lamson-Scribner, Stichenwirth, and
Antonescu (ASPEW) met to discuss electricity charges under the ongoing
UP Tubewells Project and the proposed UP Tubewells II Project. FAO/CP
through Mr. Campbell prepared the first project and is assisting prepara-
tion of the second.
2. The specific question discussed at the meeting concerns whether
water charges actually paid to farmers cover the real or economic cost
of electric power for pumping public tubewell water. A draft technical
note prepared by Mr. Campbell is attached (see Appendix 1) and compares
power and water charges for public tubewells. l/. The following considers
the question on the basis of Mr. Campbell's note and the results of
the January 21 discussions.
Background
3. The first UP Tubewells Project financed about 500 public tubewells
located throughout the State of UP. It introduced several key technical
innovations designed to raise the level of performance for public
tubewells, which is generally very low in UP. The proposed UP Tubewells
II Project would follow-up on the first project, introducing these techni-
cal improvements in some 4,300 new tubewells under the Project and upgrad
ing about 200 additional existing tubewells throughout the State.
Pricing for Efficiency and Cost Recovery
4. Two key issues relate to the question of power and water charges
under the UP Tubewells Projects:
(a) Efficiency. which relates to the type or structure of charges
or tariffs and whether the charges promote or discourage
efficient use of water and power resources; and
(b) Cost recovery, which refers to the actual level or total
receipts of water charges and whether they pay the full or
real costs involved.
5. In general, pricing for efficiency of water or power use needs to
be based on per unit or volumetric prices (e.g., in Rs /m3 or Rs/lOdb
gal. of water, or Rs/kWh of power). In this way, the total cost paid by
the user reflects the actual amount of water or power used and per unit
or
volumetric pricing generally encourages efficient and economical use of
water or power. In contrast, flat rate charges (a Rs/acre irrigated water
charge, or a Rs/horsepower power charge) are not directly related to the
l/ The draft note was edited by John F. Cunningham, ASPAC.
-2-
actual amount of water and power and tend to promote their waste andinefficient use. The use or "efficiency pricing" as a tool to promoteeconomic efficiency depends on the degree to which decision-making byusers is market (profit/loss) oriented, and of course, the actual level ofthe per unit charges involved. Per unit and volumetric pricing impactsdirectly on the costs and net returns of water and power users (e.g.farmers) in determining the mix of resources they use.
6. Pricing for cost recovery is a different issue and may or may notimpact on economic efficiency, depending on the type of pricing systememployed. "Cost recovery" pricing has primarily a budgetary impact onsuppliers of water and power and by itself, may not necessarily affectdirectly the day-to-day decisions by water and power users. Tariffs whichdo not cover costs will be reflected in budget deficits (losses) by thesupplier. A private supplier would soon be forced out of business by suchlosses, while in the public sector, government would have to make apolitical decision on whether and how to make up the deficits and thussubsidize the users. Cost recovery in the public sector is therefore ahighly political issue which by itself need not be related 'to efficientwater and power use by users, except when combined with per unit orvlumetric ("efficiency") pricing.
Volumetric Water Charges Under UP Tubewells
7. Volumetric pricing is used for irrigation water from publictubewells in UP. Farmers pay the UP Irrigation (ID) for their tubewellwater on a volumetric basis, according to the amount of water actuallyused. This promotes efficiency in water use, and is unlike our otherirrigation projects in India where water charges are levied crop-wise onthe basis of irrigated area. Water charge's based on irrigated area tendto encourage waste of water, in contrast to volumetric charges.Volumetric water charges have been considered important for efficiencyreasons (but generally ignored) at least since the first Indian IrrigationCommission in 1901-03.
8. In addition, GOUP raised the charges paid by farmers for publictubewell water in July 1981 by 20 percent in the rabi season and 60percent in kharif. UP farmers now pay for their tubewell water at therate of one Rupee for 5,000 gallons (Imperial) in the dry (rabi) seasonand 10,000 gallons in the wet (kharif) season. GOUP raised tubewell watercharges largely on its own initiative. The State has thus been relativelyprogressive as concerns public tubewell charges, both in establishingvolumetric (efficiency) pricing and in raising water charge rates.
Electric Power Charges for Tubewells
9. Electric power charges paid by ID to the State Electricity Board(SEB), however, are not based on volumetric or "efficiency" pricing. The
-3-
power charge is based on a flat rate per horsepower (Rs 450/HP) annually,
not related to actual power used. SEB charges private tubewell farmers on
a similar basis. Under a market oriented situation (e.g., private
tubewells), such flat rate charges encourage inefficiency and waste of
power which is a serious problem in power-short UP. However, public
tubewells under the project are installed and operated by the government
on the basis of specified technical standards. Unit.pricing for elec-
tricity would therefore probably have little impact on the efficiency of
tubewell operation in terms of electricity use for technical reasons. In
addition, evidence indicates government departments tend to be generally
unresponsive to direct cost and price market incentives in their day to
day operations, as compared to the private sector.
Electricity Costs and Tariff Levels
10. Based on ASPEW data (see Annex 29 of the proposed third Rural
Electrification Project; pages 1 and 2 of Annex 29 are attached as Appen-
dix 2), the real "marginal" cost of-electricity is about Rs 0.75/kWh. The
"accounting" (financial) cost based on GOUP data is Rs 0.24/kWh. Actual
"market" tariffs levied are at present Rs 0.50/kWh for domestic consumers
and Rs 0.41/kWh for industrial consumers.
11. Four different cases are relevant to the question of water charges
paid relative to power costs for public tubewells: the financial impact of
the present water and power tariff structure and rates based on the per
horsepower elctricity charge, and three alternative cases based on the
amount of power actually used with the levels of price for power based on
the accounting cost, market cost, and marginal cost of electricity sup-
plies. In addition, public tubewells can normally be expected to run
about 4,000 hours per year. New tubewells under the Bank project will
have "dedicated" power feeder line service and should be able to achieve
that level of operation. Under present power short conditions, most
public tubewells average about 2,000 hours of operation per year, and many
run significantly less than that. Two levels of running hours (4,000 and
2,000 hours) are therefore considered for each of the above four cases.
12. Present Financial Returns. ID charges farmers according to the
volume of watri pa 7). At the same time, ID pays SEB for
electric power on a flat rate basis (see par 9). Financial results for a
typical tubeoell assuming approximately average operating conditions (see
Appendix 1) are as follows:
4,000 hours 2,000 hours
(Rs) (Rs)
Water charges to farmers a/ 24,000 12,000
Power costs to ID b/ 9,000 9,000
Net gain (loss) to ID 13,000 3,000
a/ Water charges are based on water use of 106 million
(imperial) gallons costing Rs 21,200 in the dry season,
plus 78 million gallons costing 2,800 in the wet season.
b/ Power costs based on 20 horsepower at a rate of Rs 450/
horsePower annually.
-4-
13. With either 4,000 or 2,000 hours of operation annually, the water
charge actually paid by farmers to ID more than covers the cost of power
paid by ID to SEB. With 4,000 hours of operation, farmer payments to ID
for water fully cover financial operating costs (power costs, and also O&M
costs estimated at Rs 7,500 annually) plus a small additional contribution
to capital costs (actually an addition to ID budgetary resources). With
the lower 2,000 hour operating rate, farmer payments cover the electricity
costs and only part of O&M costs.
14. Under the present system of electricity and water tariffs, farmers
more than pay for the financial cost of power used. In addition, public
tubewells can be a budgetary asset to ID provided high operating rates
can be maintained (achieving high operating rates is a major purpose of
the improved tubewells under the IDA project). Financial incentives in
terms of ID budget resources encourage efficient operation of public
tubewells under the present tariff systems.
15. Accounting Cost Tariffs. Pricing electricity on a per kWh basis
at the "accounting cost" for power actually used would also yield for ID a
significant surplus of water charge payments over power costs, as shown
below. The surplus would be sufficient to cover O&M at the 4,000 hour
operating rate, but not at the 2,000 hour operating rate.

for ID, as shown below. The surplus would not be sufficient to cover O&M
costs for either high or low tubewell operating rates.

However, a 30 percent increase in water charges at the high operating ratewould be more than sufficient to cover power costs valued at market tariffrates plus O&M (full operating costs).
17. Marginal Cost Tariffs. With electricity priced at the "marginal"cost for power, water charges paid by farmers would not cover electricitycosts, as shown below. Water charges would have to be raised by 75 per-cent to cover electricity costs valued at the marginal cost of power, andmore than doubled to cover electricity valued at the marginal costs plusO&M.

Summary and Conclusions
18. Under the present system of water charges and electricity tariffs,farmer more than pay the financial costs of electricity for tubewelloperation. In addition, the present system and structure of tariffsprovides ID with a subsLantial budgetary incentive to operate itstubewells efficiently with high rates of capacity utilization. Indeed,water charges current levels would be more than sufficient to cover powercosts based on a per kWh charge equivalent to the present market rates ofelectricity tariffs for industrial users, which is nearly double the"accounting" cost tariff for the power. But they would not cover O&Mcosts in addition.
19. Requiring farmer water charges to cover electricity costs valuedat the "marginal" cost of power tariff rate would require an increase ofabout 75 percent in water charges, or an increase of over 100 percent to
-6-
cover tull operating costs including O&M. Under the present system ot tiat
rate electricity charges paid by iD to SEB, a higher water charge paid toID would simply increase ID budgetary resources while reducing net farmer
income. In addition, estimated marginal cost electricity tariffs are
considerably higher than present market rate electricity tariffs charged
to industrial (and domestic) consumers. Charging small farmers for water
at a much higher rate (in equivalent electricity costs) than paid by largeindustrial users would be difficult to justify in terms of equity.However, a special service surcharge for water from. project tubewells may
be justified, based on the improved irrigation service provided.
Recommendations
20. Based on the above discussions, the following approach to power
tariffs and water charges for the UP Tubewells II Project appearsfeasible.
(a) SEB would continue to charge ID for electricity on thebasis of a flat rate tariff. Combined with the volumetric
water charge system now in operation, this will provideID with a budgetary incentive to maintain high operating
rates on project tubewells.
(b) The annual amount of the flat rate power tariff paid byID to SEB would be raised to insure that power chargespaid are equal to the charge which would be paid at
market rates by an industrial user for the same amount of
power as used by the "average" tubewell.
(c) Volumetric water charges paid by farmers should be raised
sufficiently to cover the power charge in (b) above, plusO&M costs. This can be justified on the basis of theimproved service provided under project tubewells.
21. If justified on general policy and economic grounds, SEB could
gradually raise power tariffs for all users to reflect the "marginalcosts" of power, with corresponding adjustments in water charges. Forfarmers served by project tubewells, however, this may raise financialviability questions, since the price received for his produce is
administratively rather than market determined. In addition, most States
in India have been moving toward flat rate (rather than per unit) pricing
of electricity use in agriculture The level power tariffs and type of
pricing for electricity are serious issues which may be more effectively
dealt with in large IDA power projects, rather than a public tubewell
project where our leverage in the power sector is small.

INDIA
UP TUBEWELLS II PROJECT
Cost Recovery
1. In UP Tubewell I project, and currently proposed for UP Tubewell
II, charges are as follows:
(a) The Irrigation Department pays the State Electricity Board
a flat rate of Rs. 450 per installed horsepower per annum
(the same rate as for private well owners). It also pays
the capital cost of transformer and connection from the
11 kv line (in UP II it will pay the additional cost of
the "dedicated " 11 KV feeder from the 33 KV substation
and where appropriate a portion of the cost of the sub-
station if it has to be enlarged).
(b) The cultivator pays the Irrigation Department for water.
The water charge in the wet season is lower than in the
remainder of the year to encourage use of irrigation in
that season. The rates are as follows:
Current Rates Previous Rates(Since July 1, 1981)
Wet Season(16 April - 15 Oct) 10,000 Gals (Imp) 16,000 Gals
per Rupee per Rupee
Dry Season(16 Oct - 15 Apr) 5,000 Gals 6,000 Gals
per Rupee per Rupee
2. Comparison of water charges and actual costs of power to the S.E.B.
and providing the irrigation service by Irrigation Department depends very
much upon the hours pumped per year. Two cases are considered hereunder.
The first case assumes a "dedicated power line" will insulate the public
tubewells (PT~s) against rostering (load-shedding) and thus the arnual
hours of pumping can be expected to reach about 4,000 hours. The second
case assumes operation of PTWs of 2,000 hours per annum, which approximates
to the average of the last three or four years when power rationing hasbeen severe (in 1981/82 power availability has dropped in some parts of UP
to 1,000 hours).
3. In the first case, the assumed hours of operation are described
as follows:
Dry Season 16 hrs/day for 197 days = 3,152 hours
Wet Season 5 hrs/day for 168 days = 840 hours
Total 3,992 hours
say rounded to 4,000 hours
In the second case the seasonal hours of operation were taken as one-halfof the above.

4. For estimation of power required, a typical PTW is assumed to
have the following characteristics:
Discharge 1.5 cfs (560 g.p.m. Imp)
Dynamic Head 20 m (66 ft)
Overall Efficiency (wire to 60%water)
Power Required 14 kW
Installed Horsepower 20 HP
Energy consumed annually 56,000 kWh(4,000 hrs pumping)
Irrigation Supply: Dry Season 3,152 X 560 X 60 106 Million Gals
Wet Season 840 X 560 X 60 28 Million Gals
5. Costs of irrigation service and water charges paid by cultivator
are compared as follows:
A. With 4,000 hrs of pumping annually
- Charge paid by Irrigation Department to S.E.B. annually would be:
20 HP X 450 rps Rs 9,000
Irrigation Dept. O&M costs other than power (Est) Rs 7,500
Rs 16,500
- S.E.B. costs -
(a) At "accounting cost" of power: 56,000 X 0.24 Rs 13,400
(b) At "marginal cost" of power: 56,000 X 0.75 Rs 42,000
- Present water charges paid by cultivators served by PTWs would
be:
Dry Season 106 Mill Gals at 5,000 Gals/Rupee Rs 21,200
Wet Season 78 Mill Gals at 10,000 Gals/Rupee Rs 2,800
Total Annual Cost Recovery Rs 24,000
B. With 2,000 hours of pumpin! armiual-ly
- Charge paid by Irrigation Dept. to S.E.B. annually Rs 9,000
0&M Costs Rs 7,500
Total Operating Cost Rs 16,500
- S.E.B. costs:
(a) At "accounting cost"
Rs 0.24 X 28,000 kWh Rs 6,700
(b) At "marginal cost"
Rs 0.75 X 28,000 kWh Rs 21,000
Present water charges paid by cultivators serviced by PTWs would be:
TOTAL Rs 12,000

Conclusions
6. The above analysis indicates:
(i) With 4,000 hrs of pumping annually, the water charges paid
by cultivators more than cover the operating costs of the
Irrigation Department, but make little contribution to
capital cost recovery (the cost of a typical PTW installation
to the UP Tubewell II design is approximately Rs 480,000).
(ii) With 2,000 hrs of pumping,the water charges paid by cultivators
do not cover Departmental operating costs but does cover the
ID cost of power at present rates set by SEB.
(iii) Under the present flat tariff rate for power, the Depart-
mtental payment to the SEB barely covers the SEB costs at
"accounting" rates for power with 2,000 hrs of pumping.
If PTWs achieve the planned 4,000 hours of pumping per annum,
the Departmental payment to the SEB does not cover SEB costs
at "accounting" rates for power, and is less than 25% of SEB
costs at "marginal" rates.
It would seem that a flat rate charge for power to the Irrigation Department
should in theory, encourage them to maximize the operating hous of PTWs and
thus the returns to the PTW investment (a fundamental objective of the UP
Tubewell Projects). Alas, there is little evidence to show that IDs or a
government agency anywhere thinks and acts this way; they do not have the
incentives that motivate the private sector, namely the chance of going
bankrupt! The ID does not directly collect water charges to pay for 0&M
costs; collection is through the Revenue Department. The 0&M funds are
allocated to the ID through the general budget and are not conditional on
the performance of the ID. There is therefore no need or incentive within
the ID to relate O&M costs and recovery particularly as there is no real
'accountability' for quality of irrigation service. It is therefore concluded
that to link cost recovery from farmers to costs (direct and indirect)
of
providing the irigation service has no real impact on project performance.
Project benefits depend on the users of groundwater beievi-,Q th t
the irrigation service is reliable and cheap enough for irrsgated ar _
to be financially viable with acceptable risks 1 Power costs are a
small portion of the input costs necessary to achieve predicted agricultural
benefits to groundwater development. Furthermore,GCOUP is comited to main-
taining a substantial use of power in the agricultural sector (about 34% of
power use). It is inconveivable politically to consider withdrawing this
service for cost recovery reasons. Therefore the issues with respect to
power tariffs become:
l/ At present in UP, the main risk perceived by users is the unreliable
servica provided by public tubewells.
-4-
(i) to decide whether it is politically expedient to
recover the power cost direc-tly through water chargesor indirectly through general agricenltural taxation;
Cii) what can be done to encourage the best economic return
per unit of power used in the agricultural sector (both
private and public sectors); and
(iii) how power use can be manipulated in the agriculturalsector to provide the best load characteristics for
the SEB.
Thus, in terms of project performance, the water charge appears to be
similar to any other tax on irrigated agriculture and Government has
to judge what level of this type of taxation is politically acceptable
to farmers. What is needed is motivation to make the ID and Government
provide the promised service from a 'monopolistic' utility. One
possibility is that 'accountability' could be achieved by compensating
users for less than promised service on which the users have planned
and thus evaluated their financial risks.

FROM: Aw Yong Kong Keong
SUBJECT: INDIA: Uttar Pradesh Tabewells II Preparation. Back-to-Office Report
1. In accordance with Terms of Reference dated 15 December, I visited
India from 21 January to 12 February 1982 to collect further evidence on
conditions in the areas of the U.P. Tmbewells I- project. The purposeof the mission was to assess the performance of the standing rabi crop5
cultivator interest in irrigation, amount of water used (pumping hours5,
operation of warabundi, level of agricultural extension made available
prior to and during the rabi season, and collect additional agriculturaldata concerning the three model wells in Lucknow, Lakhimpur and Saharanpurand a few other tubewells in other districts# in preparation for appraisal
of U.P. Tubewells II Project.
2. The rate of implementation of U.P. Tabeells I Project has improved
appreciably. The number of tubewells in operation has increased from 56in May 1981 to 190- in January 1982. An additional 110 tubewells have
been completed and are expected to be energised within 2-3 months. The
completion of the projectwhich was dvhu in May 1982, will be about six
months behind schedule.
3. Power supply is available to most of the completed tubewells on an
average of about six hours a day due to rostering on rural power lines.
Tabewells on unrestricted power receive an average of 10 hours of power
supply per day. Effective utilization of power and irrigation water is
approximately 50% in most tubewells. All the farmers interviewed are
enthusiastic about the Project Tubewells, although findings indicate that
approximately 20% of the areas irrigated are attributed to private sourcesof irrigation. Approximately 80% of power available is supplied in the
night. A study of nighbirri tion in five tubewell areas indicated that
utilization varies from 25-504. Extension services on water management
are non-existent since farmers allotted irrigation supply at night are
left entirely on their own to open the outlet to irrigate their fields.
4. Farming practices have not changed significantly since the imple-
mentation of the project. The type and amount of fertilizers and pesticides
applied generally remain unchanged, and crop yields have not increased
appreciably. However, the area under rabi cropping has increased.

5. The extension service is ineffective. Two agricultural
supervisors recruited within the last three months were posted to two
model tubewells, one in Govindpur and the other in Lakhimpur, specifi-
cally to collect agricultural data andin addition, to establish and
supervise the demonstration plot in the model tubewell in Govindpur.The only other existing staff is the Agricultural Officer whose fieldvisits are mainly confined to these two model tubewells, and whosemobility is constrained due to lack of transport and inadequatetravelling and other allowances.
6. Agricultural data to be collected from the three model tubewellswould be inadequate for preparation of U.P. Tbewells II. In Lakhimpurand Saharanpur the data would represent only the present rabi crop.Yield data of the previous rabi crop, collected by the Statistics Division
of the Department of Agriculture, could not be reviewed as crop plans fromwhich random samples were taken were not available. The Project Director,U.P. Tubewell I is aware of the need to collect and compile agriculturaldata (crop yields in particular) of at least one tubewell from each of the
12 districts.
7. I am now preparing a full report on nmr findings. As you are aware,it is proposed that I return to collect further information in April, ahead
of the appraisal mission.

FROM: G. . Tibor, Chief, ASPAC
SUBJECT:Private vs. Public Tubewells in the Gangetic Plains
Further to your recent verbal request this memo explains our views
on development options in UP. To a very large measure the views are also
applicable to the remaining areas of the central and western Gangetic
Plain.
1. Before considering an expansion of Public Tubewell capacity in UP
it is appropriate to review alternative types of groundwater development
in the State and their respective roles.
Private wells
.These include dug wells and shallow tubewells. There are several
hundred thousand in UP, collectively contributing the major part of the
existing groundwater development in the State. Installation is continu-
ing. The shallow tubewells are of a very simple type, usually referred to
as "cavity wells". They consist of an iron pipe, driven through the
overlying silty strata into a sandy layer at shallow depth, where a cavity
is formed by pumping and extracting of sand in the immediate vicinity of
the pipe end. The roof of the cavity is provided by the overlying
silty-clay layers. A centrifugal pump is mounted at ground-level, or in a
pit sunk below ground-level. The pump is driven by a diesel engine or an
electric motor. These wells are either financed by the farmers out of
their own funds or through institutional credit (ARDC refinanced). There
are several disadvantages to the use of these rather simple wells.
2. Firstly, because the pump is usually located at the surface and
lifts by suction the system can only operate if the dynamic water table
is located within some 6 to 8 m of the ground surface. In contrast tur-
bine pumps, used in public tubewells, are located below the groundwater
surface within the well casing and operate by lift rather than by suction.
Subsurface conditions permiting development of a simple "cavity" well are
not found everywhere. Also the necessary high water tables can only be
maintained for the foreseable future where natural recharge is in excess
of potential extraction, such as in the eastern, high rainfall areas, of
the Gangetic Plain. However, for the central and western parts of the
basin the situation is quite different. Theoretical studies and mathe-
matical modelling have indicated, that optimal use of the aquifer (in the
future) is possible only through a lowering of the water tables in the dry
and hot seasons, to create necessary storage volumes to accomodate the
available natural recharge. At present the limited storage volumes in
the aquifers (because of the high water table at the end of the dry
season) result in a "rejection" of natural discharge, quite early in the
rainy season, with large amounts of potential recharge flowing as "sheet
flow" over the ground surface towards the rivers where they increase the
flood discharge of the system.
-2-
3. Secondly the discharge of the shallow cavity well is usually
limited to some 0.5 cfs, versus a discharge 3-6 times larger from a typi-
cal deep tubewell. For a certain quantity of water to be extracted from
the aquifer through shallow wells, 3-6 times more pumps and motors are
required. The quality of the small pumping equipment is also much worse
than the more sophisticated pump and motors used in the public tubewells.
Their is considerable difference in pumping efficiency between the two
types of equipment and thus the overall cost of lifting water from several
small shallow wells versus one deep well, is much higher.
4. The advantage of the private well over the present type of public
tubewell lies mainly in its flexibility to provide water to the farmer
when he needs it. However, with the newly redesigned public 'well, the
reliability of service from these wells is greatly improved. The public
well has also distinct advantages for the small cultivator who cannot
afford his own well and must depend on the good graces of his larger
neighbor, if public supply is availble.
5. The discharge of a public tubewell is frequently 1.5 cfs, and may
be up to 3 cfs. The desirable rate of delivery to a small cultivator
supplied by a tubewell is of the order of 0.5 to 0.75 cfs, in seasons when
crops other than paddy are being grown. This rate of flow is determined
by considerations of efficiency of water distribution within the farm or
on the field. Within limits, the desirable stream size is independent of
the size of farm, although size determines the period of time (hours per
week) during which this flow is received by a particular farm, i.e., its
share of the weekly pumping hours. The delivery system is designed for
rotational supply, 0.75 cfs in fact being the nominal rate of flow to the
farm adopted for the UP wells. With a 1.5 cfs tubewell it is thus neces-
sary to divide the well-discharge between two farm outlets at any par-
ticular time; with a 3 cfs tubewell between four outlets, etc. To achieve
such equitable division between outlets which may be at substaltially
different distances from the tubewell and at different ground elvations
(i.e., under different hydraulic head in the case of pipe systems) is the
principal technical problem in tubewell water distribution.
6. The traditional method of distribution for Public Tubewells in the
Gangetic Plain has been either by open channel, or by up to 1 km of buried
pipe followed by open channel. Total length of lined channel, or of pipe
plus lined channel, has been about 1.5 km, followed by 1 to 2 km of
unlined main channel and thereafter unlined field channels.
In the development of the UP Tubewells I project considerable
attention was given, initially, to improved lined open-channel systems.
However, a number of problems associated with open channels could not be
avoided. These included:-
- Right-of-way
In the highly sub-divided small-holdings of UP
(particularly central and eastern areas) resistance toloss of land for open channel construction by cultivators
was a major problem. Right-of-way was also a substantialitem of cost.
- Water losses in transit
Losses through frequent damage to lined channels,through seepage from unlined channels, and from illegalbreaching of unlined channels were a major consideration,and also resulted in a low-level of confidence in supplyon the part of cultivators on the outer perimeter of a wellservice area.
- Maintenance
This was a perpetual problem with open channels, withcultivators unwilling, and the Irrigation Department unableto cope with the situation.
- Poor response to interrupted power supply
Time lost in re-filling open channels on resumption ofpumping after frequent power stoppages disrupted rotationaldelivery schedule and led to a further loss of confidence inthe system.
It was concluded that in the circumstances of UP only a buriedpipe system could provide the security necessary for realization of thefull agricultural potential of the tubewells.
7. As noted earlier, the distribution system has to divide and equi-tably distribute the 1.5 cfs tubewell discharge between a number of out-lets, each delivering in turn 0.75 cfs, and located at varying distancesfrom the well and at varying ground elvatons. This can be done in twoways:
(i) By installing a flow-regulating valve at each outlet, of atype which controls the discharge at a predetermind rateregardless of hydraulic head at that point. It is alsonecessary to ensure that not more than two such valves areopen at any one time (for a 1.5 cfs well).
-4-
(ii) By dividing the flow into equal 0.75 cfs streams at thetubewell, each serving a separate pipe sub-system on each ofwhich one outlet only is in operation at a time.
Both of the above alternatives have their field of application.In the case of the UP projects the area supplied by a tubewell is rela-tively large (80 to 100 ha), more than twice as large as would be the casewith a well designed to irrigate paddy at 100% irrigation intensity. Thisis for two reasons. Firstly equity of groundwater use--there is insuffi-cient groundwater to supply all potential users at such high intensity.Secondly, the most important irrigated crops in UP are in the dry season(rabi and hot weather) and are other than paddy, generally with con-siderably less water use. However, even with such crops the rabi irriga-tion intensity under the wells is less than 100% for reasons of socialequity.
In these circumstances the length of distribution system for a1.5 cfs well is usually large. Further, because of the small size ofholdings the desireable service area of each individual outlet from thedistribution system is relatively small (4 or 5 ha), implying a relativelylarge number of outlet valves (typically around 20) per tubewell.
Both of these circumstances weigh in favour of the second of thetwo alternatives discussed above, which is the system in fact adopted forthe UP I project. The division of the flow at the tubewell into separate0.75 cfs sub-systems each serving one outlet at a time has also madepossible the adoption of the closed loop layout for each sub-system, withconsequent substantial reduction in pipe sizes and cost.
8. Power supply is a critical item for any tubewell development, andpower is in short supply in UP. Major new additions to generatingcapacity are in prospect, but it is anticipated that the very great poten-tial demand in the State will always out-pace generating capacity, andsome degree of rationing will continue indefinitely.
In the circumstances great importance is attached to the Govern-ment of UP's assurance that regulated power supply will be given toproject tubewells, via "dedicated" feeder lines serving clusters of wells.It is proposed to avoid operation of project wells in the three or fourhours of daily power system peak, in the interests of minimizing theeffect of the tubewell installton on required power system capacity.
9. In the past the IDA has strongly supported development of privatewells in all parts of the Gangetic Plain. A number of large credit opera-tions assisted farmers who could afford this investment. For farmerswhose landholdings did not justify a well of their own, or in areas wheregroundwater was too deep for the typical shallow well, public tubewelldevelopment was promoted. Because of deficiencies in the technologies
-5-
used and the resulting difficulties in managing the public wells, the
service from them was unreliable and expensive and in most cases the
farmers even refused to pay watercharges to cover operating costs. Thus,
because of a lack of suitable technology (used in the public sector), the
private sector took over (wherever this was possible) even though the cost
of water produced from the private wells in most of the cases was con-
siderably higher than from a properly constructed and operated public
well. The second important drawback of uncontrolled private well develop-
ment is that it will constrain in the future optimal groundwater exploita-
tion in large parts of the Gangetic Plain (see para 2).
10. Private wells usually have a life expectancy of about 10 years.
Therefore, a gradual changeover to public wells may not be too difficult,
if the necssary preparatory work is started in time. Our experience with
the "irrigation sector" in India has indicated, that even though, the
professionals working on such problems are aware of the need for change
(such as a move to more optimal use of the resource), without outside help
they will not be able to deviate from their traditional approach to
development. Thus it would be of great importance, if we could promote
with the state groundwater boards the necessary theoretical research and
modeling work in the affected areas.l/

1/ For example, a condition of IDA's US$350 million contribution to the
recently negotiated ARDC operation could have been the requirement to
do "modeling" work (by the Groundwater Boards) in the critical areas
of UP and Haryana. The technology for doing these models has already
been introduced in the National Institute of Hydrology in Roorkee,
under the UP modernization, project preparation work.

OFFICE MEMORANDUMTO: Mr. B.A. Nek j DATE: December 17, 1981
FROM: G.L. Corey -
SUBJECT: Private vs. Public Tubewells - Uttar Pradesh
ASPAC's & GOI's views with regard to long range groundwater
development in the Gangetic Plain by using deeper tubewells are not
questioned. No one can argue that rational development of the aquifer
will not require deeper tubewells. This is the only way to increase
the use of the groundwater resource.
However, when we equate deep wells with public and shallow
wells with private and when we indicate that public deep wells are
more economic we make assumptions. These are:
(1) Deep tubewells can best be constructed and operated
in the public sector.
(2) Water from deep tubewells (public) will be used as
efficiently and effectively as water from shallow(private) wells
We now have introduced areas where differences of opinion
might arise.
It is my view that it will be some time before public tubewells
will be managed as well as private tubewells where agricultural production
per unit of water is equivalent. This is the reason, I believe, that
agricultural extension and research should be closely correlated with
expansion of deep public tubewells.
On the other hand, it will also be sometime before deep public
tubewells will lower the water table sufficiently to replace private
tubewells. So perhaps the transition from shallow, private tubewells
to deep, public tubewells will be smooth.
Another development approach could have been to assist farmers
with development of private tubewells. These gradually would have
needed to be deeper and deeper. It would have also meant switching
from dug wells to tube wells along the way. This approach would have
taken longer but would, in my opinion, have produced better results if
it could be achieved. However, with all the social, organizational and
associated management problems it would have been extremely risky.
Evidently project planners, and perhaps wisely so, opted for the public
approach to development of the groundwater in this area.

Dear Gaby,
UP Tubewells IIPreparation for Appraisal
I visited Lucknow on November 4th and 5th for further dis-
cussion of State proposals for UP II. The visit coincided with the
UP I supervision mission of Messrs D.D. Taneja and G.L. Corey, and
meetings with government were held jointly. Progress on construction
of UP I will be covered by the supervision mission report and is
not referred to herein.
Preparation for UP II remains on schedule target date for
final appraisal early March, subject only to the fact that Rabi 1981/82
yields will have to be estimated from standing crops. Harvesting will
be in Mareh/April.
Items covered during the visit included the following:
- Cost estimates:
The State will complete a detailed revised estimate based
on current experienced costs within the next few days.
The total cost per 100 ha (1.5 efs) well is likely to be
close to Rs. 473,000 at November 1981 price levels(without physical or price contingencies). This may be
compared with the following:
Appraisal report estimate (withoutphysical or price contingencies)end '79 levels Rs. 400,000
Physical contingencies provided in
appraisal (7%) Rs. 28,000
Price contingencies provided in
appraisal (25%) Rs. 107,000Gross 535,000
The reason for the appraisal "saving", compared with
the appraisal figures including contingency allowance,
. . 2Headquarters: Washington, D.C., U.S.A.
2
is largely the flat level of PVC costs over the lasttwo years.
- Dedicated power feeders:
Confirmed with Minister of Irrigation and Power, alsonew Secretary, Irrigation and Power, that dedicatedfeeders will be provided virtually throughout. (Alsoin remainder of UP I). The concept of a "cluster" ofwells, from the power supply and operation and manage-ment viewpoints, was also clarified with the ElectricityBoard and Irrigation Department.
- Hydraulic control system:
The modified system introduced in August, preservingthe fully automatic feature with flood control butusing an entirely brick-work structure to facilitateconstruction, is now in satisfactory operation andwill be used throughout UP II and the remainder ofUP I. This removes the troublesome issue of elevatedtank vs non-automatic distribution chamber.
- Number of outlet valves:
Confirmed that this will not be less than 20, per 100ha in UP II (and remainder of UP I). Early in UP IItrials will be made with a greater number of outlets,
particularly in the eastern zone.
- Rehabilitation of old wells in UP II:
This will be done on a pilot basis only, to determinecosts and benefits with regard to a possible futureUP III.
- Data collection for appraisal:
As flagged earlier, and to be discussed in the currentsupervision report, the planned Monitoring and Evaluationgroup has not been effectively established and datacollection has been poor. The State was asked during thelast CP mission to select three representative wells onfeeders largely free of rostering (to simulate UP IIconditions) and to examine their operation and productioncritically in Rabi 81/82. This request was reiterated,and will now be monitored by NDO, with a view to a fullreport for appraisal.
- PVC supply situation (resin and pipe) for UP II:
This is unlikely to be a problem. Substantial additionalpipe extrusion capacity has recently been installed.Irrigation Department has agreed to contact appropriate
3
Government departments (Licencing, Petroleum Products)and to prepare a note on both resin and pipe supplyfor appraisal.
- Agricultural supporting services; also Monitoring andEvaluation. Proposed change in organization for UP II.
The lack of support by Department of Agriculture has been
referred to in previous notes, also the real difficultyin keeping effective staff posted to M and E in Lucknow.
The Groundwater Wing of the Irrigation Department has
shown itself willing to fill the gap left by the Depart-
ment of Agriculture, but has had limited technical
resources. A possible radical change in organization for
agricultural support was explored with Irrigation Depart-ment, Secretary, and Minister, and will be discussed with
the Bank in December. This would give to the Groundwater
Wing, or an agency of it, possibly the 0& M group, virtually
the role of CAD. Agricultural staff would be seconded to
it, (an extension officer possibly per 40 wells), butwould be effectively under the direction of the Chief
Engineer, Groundwater Wing. The Monitoring andEvaluation function would also be transferred from Lucknow
to the 0 and M divisions, as far as data collection is
concerned, and data analysis only (by computer, which
the Department has) would be done in the Chief Engineer's
office in Lucknow. A detailed proposal will be reviewed
with Bank and discussed with the UP government in January.
- Relative roles of D.I.T. Wells, Augmentation Wells, and
Canals in irrigation in UP.
An analysis is being prepared by C.P. incorporating
discussions with the government.
- Next action:
Draft statements on principal topics in appraisal will be
reviewed with the Bank in December/January, and discussed
with the government at secretariat level in the second half
of January.

Dear Gaby,
UP Tubewells I & II
I visited Lucknow in connection with preparation of UP II
on 28th and 29th September 1981.
A summary of progress on UP I up to end August is attached.
The number of wells in operation was 57, and number of wells
drilled and developed was 314.
Progress at the moment is slowed by monsoon weather and some
delay in supply of PVC pipe. However the latter problem will be
remedied by delivery of an additional ex:trusion machine to WAVIN
next month. Some teething problems with hours-run meter and control
black box are being overcome. Completion of UP I is now projected
for September 82 but completion of drilling 500 wells is likely by
end November 81. COUP is now formally requesting extension of the
project to 640 wells through "savings" largely due to the original
provision for contingencies and price escalation not being invoked.
Although one of the O&M Divisions which should provide supportto cultivators and monitoring has belatedly been sanctioned, only afew officers have been posted and these without associated staff
and vehicles. Agriculture Department support consists of second-
- ent of three officers only, to Irrigation Department. These are
preparing leaflets on crops and practices for the coming rabi season,
for distribution to cultivators in lieu of agricultural extension.
Irrigation Department also proposes to establish one demonstration
plot (on a selected cultivators farm) n'tar each tubewell and to
provide inputs at no cost, particularly for UP II. This will require
participation of at least 50 agricultural officers, presumably on
deputation from Agricultural Department.
In discussion with the State Minister for Irrigation (the full
Minister was in Delhi) it was put to him frankly that the system
proposed in the U.P.I. project document for extension and monitoring
2
had failed1 due to almost total lack of support by the Agricuit,,
Department and the Secretariat and that the mission would recoimr..
to Bank that for Ur siemetle assurances should no longer be sought
but that disbursement should be made conditional on satisfactory
supporting services for each well.
It was agreed with the C.E. Tubewells that his three agricultural
Officers should give pre-season extension advice and follow very
closely the rabi season performance of three wells on "dedicated"
pouer lines (unrati oned), representing anticipated UP II "with
project" conditions. Functioning of the rotational system and
operation at the cultivator level will be monitored, and pultivators
on each outlet valve will be interviewed. This is much reduced
in scope from the action envisaged in the UP I project document,
but is as much as can be achieved without the sinews suggested for
the UP II document.
The UP II project report of April 81 prepared by theState is
being cleared by G.O.I. for formal transmittal to the Bank.. Thea*
principal components will be:

1. This note is a draft of one of a compendium of technical papers
on various features of water distribution systems in India which is
being prepared under World Bank sponsorship by a number of contributors.
The note is primarily a discussion of alternative technologies, limitations,
and areas of application. This first draft is brief and is written in
response to an immediate need for an interim evaluation. A more detailed
paper will be prepared within the next months. Comments and contributions
of experience by those engaged in this area would be much appreciated and
will receive full consideration in the later issue.
Scote
2. The canals discussed are broadly in the range of capacity up to
25 ofs, although some of the matters discussed relate also to larger
channels. Linings in loamy or granular soils, and also in expansive clays,
are considered.
The Situation
Lining cf small canals is technically very simple, in the abstract,
but in practice a number of problems stem from the large quantity of such
lining required, running to thousands of kilometers in a typical project.
Problems of rate of installation, supply of materials, quality control
in remote areas, and particularly cost, are aggravated by the very size
of most lining programs. Simplicity of installation, durability and low
seepage loss are the principal objectives, but always within tolerable cost
limits. While much excellent work has been done on linings, and extensive
experience has been gained in scme areas and soil situations, very pressing
problems remain to be resolved under other conditions. Further, the recent
escalation of fuel costs with its repercussions on price of cement and
bricks has heavily underlined the question of cost, even with traditional
lining techniques.
Problems
4. Some problems in channel lining are common to all types of soil,
./ Please address to D.E. Campbell, c/o World Bank Resident Mission, 55 Lodi
Estate, New Delhi 110003
and others are particular to certain types (e.g. expansive clayson the one hand, and wind-erodible desert sands on the other).As the most difficult soil from the lining viewpoint is certainlythe expansive clay, that situation is discussed first, and subsequentlynon-cracking silty soils.
5, Channels of the size in question are excavated to a relativelyshallow depth, commonly less than two feet. Soil moisture contentvaries considerably, seasonally, dovn to that depth, which meansthat dimensional chan,es occur in the soil unless constrained by forceswhich far exceed the reaction which could be offered by any smallcanal lining. -Thus, movements occur even in the undisturbed soilin which the canal section is cut. In the upper portion of the lining,usually placed against fill, the problem is aggravated. Firstlythe range in moisture content is greater in the fill section (beingnearer to the surface), which would lead to considerable movement evenif the fill were ideally compacted. Secondly the fill is not usuallywell compacted, and regular settlement may add to expansion/contractionproblems. The reasons for poor compaction include the blocky natureof such soils when worked dry, the narrow range of moisture in which theycan be effectively compacted when wet, the small size of embankment beingconsidered (below the range of most mechanical compaction equipment)and simply the cost of providing water for compaction. Construction ofa broader "pad", wide enough for compaction by heavy equipment, in whichthe canal section is subsequently excavated, removes the problem ofsmall size. However it is debatable whether moisture-induced expansion/contraction is any lesser or greater in well compacted soil of this typethan in poorly compacted soils.
6. For higher embankments than under discussion (distributaries,etc.) the height of fill is likely to be sufficient to make settlementa primary factor (although not to the exclusion of moisture movement),requiring proper compaction. However, for an embankment of one to twofeet in height only, expansion/contraction is likely to be the primaryfactor, even to the extent of cracking and crumbling an already well-compacted fill. The merits of compaction in such circumstances must bejudged on the basis of the character of the particular soil in question.
Pan'e 3
her or not ccinpaction is carried out, there will be subsequent
vcment of both the cut and the fill portions of the channel.
To further aggravate the problem, this movement is not uniform, even
in a cut of considerable depth in such soils.
One solution is to remove the offending soil, by ovex-
excavation, and to replace it by granular or other non-expansive
material (e.g. murrum). Where such material is available at acceptable
cost this is a very satisfactory solution to the exrpansion problem,
although it poses the question of what thickness of granular material
is required to insulate a lining against lateral pressure from adjacent
expansive clay soil. It is more than a nominal amount, and varies
with depth of fill. Where such non-expansive material is not available
the lining must be designed to accommodate soil movement, or alternatively
for smaller channels the "lining" may be free-standing and not in
lateral contact with the soil.
8. The above discussion is with regard to movement and pressure on
linings from expansive clay soils. Turning to soils in general,
including the commonly occurring non-expansiva silty loams, there is
a further source of pressure on linings which is frequen-tly destructive.
This is pressure exerted by plant roots, ei.ther by plants growing behind
the lining cr in joints or cracks on the watei-side of the lining.
The former msy commonly be observed on linings after two or three years
of service. Vegetation growing on the inside edge of the canal banks,
attracted by the small amount of moisture seeping through -or condensing
behind aany -type of lining, will send roots down behind and in direct
contact with the lining. The roots expand as the plant grows, exerting
a considerable pressure on the lining. Where even a minor crack develops,
particularly at a joint, the roots will follow the crack and may expand
rapidly causing dis.)Iacement of the lining, enlargement of the crack,
and progressive failure. Roots penetrating from the water-side of the
lining, from plants lodging in faulty joints and extending their root
systems behind the lining, are also a common cause of displacement of
linings, particularly tile or block linings. Such deterioration is
hastened in the case of certain "black-cotton" soils by erosion of soil
from immediately behind the- lining vinerever a defect develops (.e.g block
displacement, or deterioration of joint-filler in slab linings) which
perits water to move back and forth through the lining at that
point. Progressive washing--out of soil occurs, and eventual local
collapse of the lining. This has occurred on a spectacular scale
in some main canal linings in India, where a lining was placed directly
on such soils without sufficient attention to a filter layer of
granular material between soil and lining.
-Possible TIrpes of Linin. and their Performances
9, To summarize the above discussion, in expansive clay soil
-ovement behind the lining cannot be avoided unless by over-excavation
and backfill with granular material. In Ey type of soil a small canal
lining is likely to be subject to local pressure from developing plant
roots behind and in contact with it, which may lead to opening up of
cracks and progressive deterioration.
0. The expansive clay situation, where granular fill is not available
or is costly, requires a lining which can accommodate soil movement
Nithout cracking. Both a degree of flexibility and also stractural
continuity are required, to avoid displacement (kicking out) of one lining
Velment relative to its neighbour under the influence of local soil
pressure.
-S1. The non-expansive silty soil does not require flexibility of lining,
but the lining must be robust enough not to be readily displaced by plant
,OOt s nd it must not aggravate the latter problem by seepage at joints.
The various types of lining available are discussed in relation
to these requirements.
(M) Brick channel with vertical sides
13. This is not strictly a, "lining", as the channel can stand
independently of support from adjacent soil. However, usual practice is
t o backfill against the brickwork to form a foot-way on either side at
channel-top level.
-14. This form of channel, with depth up to about fifteen inches and.
idth 'of water-wmj up to two or three feet is an excellent solution where
ed Equ~aty brick -is available. It has had wide application in Punjab,
e r
,p. and elsewhere. The technology, including merits of internal
ea mortar plastering, has been well investigated and documented.
, it is noted that:
. Such construction is no longer low-cost, and is not necessarily
the most cost-effective form of lining even in areas where it
has traditionally been used.
- Satisfactory clay soils for brick manufacture are not available
over very large areas of central India.
- The lining is very rigid and should not be used where it
will be exposed to lateral pressure from expansive clay soils.
INeither should it be used on a significant depth of fill (above
2 to 3 feet) unless the fill is fully compacted and non-expansive,
as a very slight amount of settlement of the fill will cause
cracking and leakage.
- The limit of capacity of such linings is dictated by the
structural stability of the verticle walls of single.-brick
thickness.
15. Acnowledging the above limitations, the brick channel is
nevertheless a robust and practical form of construction in appropriate
circumstances.
(b) Precast, or estruded, full--section concretechannel lining units
16. Structurally these represent the corcrete equivalent of the vertical-
sided brick channel discussed above. They will stand without support from
adjacent soil, although common practice is to back-fill against them.
Sectional shape is. not limited to rectangular but may also be trapezoidal,
half-round (generally formed by spun pipe process),or half-round up to the
diameter and vertical above that level (formed by "extrusion" process).
17. The upper limit of area of water-way for integral units produced on
the extrusion machine is about 1.25 sq.ft, but the possibility of production
of units of greater size is being explored. The extruded units are 25 cm in
length (limited by the nature of the production process) and have shaped
joints to permit positive mortar jointing. Extrusion machines (these are
similar in principle to those used in hollow-block manufacture) are now
produced in India. I/ Such lining units. can be very effective. The
following points am noted:
- Production requires good aggregate and close quality control.
Where poorly shaped flaky basalt aggregate is used a supplemental
mortar slurry wash may be desirable, but not othersise.
- Installation is simple but requires care in jointing. The shaped
joint permits various joint sealing techniques including bitumen
retained behind mortar pointing.
- In expansive clays granular backfill may be used, or alternatively
the units may be left free-standing without backfill, or with
random backfill to half-height only. 2/ In severe soil situations
the nominally unreinforced units may be tied together in lengths
of some 5 or 6 metres with a single light rod in the formed
longitudinal reinforcement groove provided at the top of the unit
on either side (the rods are applied after installation of the
units, and mortared In place). This adds structural continuity
and distributes cantilever loads on the walls of the units. In
normal circumstances this ex-pedient is not required.
- This type of lining unit may be used in all soil situations.
- Where half-round spun pipe, usually lightly reinforced, can be
provided of similar net area of water-way (allowing for free-board)
and similar cost, it is equally as effective as extruded sectione.
However, the provision of freeboard within the half-round section
reduces gross area considerably, and the pipe is usually too thir
for freeboad to be provided by adding supplementary height to the
half-round by building up with dry-pack mortar or mortared brickwork.
Half round erternal collars must be used at all joints.

at canal-top level may be practical even in expansive soils provided
that it is narrow enough (e.g. 8") not to cause lateral expansive
pressure on the lining.
- The "linings" discussed in (a) and (b) above are capable
of standing without support from the adjacent soil, and
indeed should be so placed when the soil is expansive, as
they are structurally rigid in the transverse direction.
(Longitudinal flexibility may be provided at joints).,
The remaining linings described are not designed to stand
freely; they rest upon and are supported by the adjacent
soil. All linings for channels larger than the size
limits referred to above are necessarily of the non-self-
supporting type (excepting reirforced concrete flumes).
Smaller channels may be optionally self-supporting or not.
(c) Brick tile linin of traoezoidal canal section.
18. This is the traditional method of lining canals of all sizes in
-some areas of the north-west, e.g. the Rajasthan Canal command. For larger
canals a double layer of tiles is used, and for smaller channels a single
layer. Various procedures of mortar application on the soil (sand in the
RCP case) prior to placement of the tiles are used. For the double-tile
lining the mortar layer between the two tiles is the primar water barrier,
the outer tile protecting it and the inner tile providing a base for its
application, also weight and structural stren,'th of the composite sandwich.
The single-tile lining, which is more relevan- to the small channels
discussed herein relies primarily on a rich mortar layer applied over
jgreliminary priming of the soil surface by leaner mortar and cured before
' application of the tiles. The tiles protect t;he mortar layer, but also
provide a secondary barrier. The joints between tiles are filled by
surplus mortar squeezing out between successive tiles as they are bedded
into -n underlying mortar plaster.
19. The single-tile lining is very successful in Rajasthan (except
where left unsupported by wind erosion of adjacent sand fill). However it is
also sufficiently costly at present materials prices to cause some concern over
the watercourse lining program. Reasons for its success in Rajasthan, and
that of the larger double-tile lining include:
- High quality of the coal-fired baked-clay tiles
- Careful supervision, and meticulous attention to the
onstruction of the mortar barrier
- The canals are in non-expansive material, for the most
part dune sand. There is no soil movement or
pressure.
Particular attention to compaction of fill (sand)
in embankments prior to lining.
20. The lining would be less uuccessful for small channels in
expansive clays, due to the certainty of sufficient movement to cause
cracking, at least along the bottom coniers. A flexible water-tight
joint between sides and bottom could be devised to reduce this problem,
but would not insure against transverse cracks, due to differential soil
movments along the length of the canal.
(d) Linin-.of trae-zoida! cana! sections wthmortar tiles or lair ,ointed concre-eee si-aDs.
21. In principle this system is similar to the brick tile lining
discussed above, but cement-mortar tiles or pre-cast concrete slabs
are used instead of brick tiles. The cement-mortar tiles necessarily have
plain square edges, because of their method of manufacture (by press)
and their thin section. Precast concrete slabs may have either plain
square edges, or configured edges. The latter are discussed later; for
the rcaent square-edged slabs are referred to.
22. The square-edged mortar tile is bonded to an underlying water-
retaining mortar layer as discussed in (c) above. While the tile itself
may be of high quality and density it is of relatively light weight.
Bren if well bonded to an underlying mortar membrane, it nevertheless
provides a relatively thin composite lining which can be readily displaced
and cracked by minor soil movement or plant root growth. It is emphasized
that a lining cannot be bonded on to a body of soil - the mortar bonds to
a surficial layer of soil only, which contributes nothing to structural
5t2Dility. A thin tile bonded to a thin layer of mortar is a fragile
lining if exposed to any external pressures. If not well bonded, or if the
bond deteriorates through repeated wetting and drying or poor quality of
mortar, it- is even more fragile, and lacks even the stabilizing dead-weight of
the heavier concrete slab. Deterioration is likely to develop rapid.ly after
a year or two of service.
23. The concrete slab with plain joints on a water-retaining mortar
layer has the advantage of weight, which gives some structural stability.
In non-expansive soils with little possibility of significant soil movement
such a lining may last well if the quality of construction is good, includrmg
compaction of fills. However, it is a rigid lining and slight movement or
settlement of soil is likely to initiate cracking, which may be followed
Page 9
root expansion and further deterioration. It should be used
muitable soil situations.
(e) Cast-in-Place Concrete Lining
The cast-in place process produces a rigid lining applicable
the same circumstances as the concrete slab lining discussed above,
i.e. to non-expansive soils. With close supervision, including compaction
of embankments, concrete quality control, and proper curing, a ve2r
satisfactory lining is produced. Without such adequate control the end
product can be very inferior. A substantial proportion of cement destined
for the work can be misappropriated, and the resulting deficiencies
in quality cannot be fully remedied by plastering.
25. Choice between cast-in place lining or pre-cast elements largely
centers on the level of supervision available, in- the field vs at the
pre-casting plant.
(f) Use of plastic sheet in conjiunction with otherjning materials.
26. Use of plastic sheet only, covered with a protective layer of-
earth, is cxcluded from present discussion du.e to its vulnerability to
damage in small canals accessible to livestock. The fill in the fully
saturated submerged condition cannot- resist penetration by hooves. Further,
the, shallow depth of such canals permits growth of vegetation throughout
the perimeter of water-way, with likelihoo& of roots penetrating the
underlying sheet. The use of buried plastic sheet in larger canals
or-reservoirs is outside the scope of. these notes.
27, In.-small canals plastic sheet may be used behind concrete
(or brick) linings for either, or both, of' two -reasons:
-- To -temporarily-seal wet-concrete or-mortar from the
a jacent soil, thereby preventing excessive migration of -
water from the mix into the soil.
-. As the primary permanent water-barrier, the concrete -or:
brick lining placed upon it -being for :protection of- the
sheet, and possibly providing a -secundary barrier.-
28.- The first app)cation ia auseful constrxction ezpdIent '
sc" soil :situations. The sheet may be verrathin(0.l1 mm arid -is likely
to zgst Ra. 2.50 to ,.Rs3.50 per :squ-e meter.:.
29. The second application is intended to be permanentiy exieQi a.
and raises several questions. Given sufficient thickness it can certainly
perform satisfactorily. The issue is what thickness is required.
30. Current practice is to place a mortar layer on the plastic
sheet and to bed the concrete tile on to it, in effect forming a rigid
lining bonded on to a flexible membrane. Placement of the concrete
tiles loosely on the membrane is not effective as they are easily displaced,
and weed rooting and penetration in silt-filled interstices between tiles
would occur. In non7-expansive soils the plastic sheet technique can be
very effective provided that the sheet is thick enough to resist penetration
by plant roots and termites. A thickness of the order of 0.5 mm is probably
desirable for permanence, with cost some Rs. 10/- per square meter
(polyethylene).
31. In an area of expcansive soils the applicability of plastic sheet
as a permanent primary watei-retaLining memberance, in conjunction with
a rigid protective inner lini-g, is much more questionable. Movement is
certain to occur in such soils, probably irregular movement, displacing one
tile with respect to its neighbor. hile the plastic sheet of itself is very
fleDible, the mortar bonds it to the tile to some degree, and unless the
sheet is of considerable thickness deformation of the sheet is concentrated
entirely at the point of displacement of one tile with respect to its
neighbor. ?apture or teari.; of the sheet is likely to result 1/.
The bonding of a light-weig4t flexible sheet to a rigid lining is successful
only as long as the latter does not crack, or become displaced.
(g) Precast concrete slabs -ith secial oints
32. The ideal system in an expansivs soil would be the use of precast
slabs jointed in a manner ihich provided a degree of flexibility but also
restraint aga.inst displacement, and at the same time water-tightness. This
apparently incompatible combination can be provided t-o a considerable degree,
but only with much more attention in manufacture than is customary in
production of precast slabs.
33, Types of joint in common use, and developments from them are shown
on Plate 1.
Unless the sheet is etremely elastic, as with butyl rubber, which
unfortunately is too costly for this application.
Fig 1A. This is the plain square-edged slab. It provides
control on the distance between adjacent slabs when placed, and
c 0 sequently on the thickn ess of pointing. A common defect is placing
of slabs too close to each other leing insufficient space for
penetration of mortar. Pointing then becomes a surface treatment only.
F=rthermore once the most minute shrinkage crack develops in the mortar
pointing the joint provides no resistance to shear displacement.
The only merit of the joint (except in the application discussed under (d),
for non-expansive soils) is simplicity of manufacture.
35. Fi.g, 13. This ensures a definite minimum thickness of mortar
jointing, but offers no resistance to shear displacement other than the
bond of the mortar, and none at all if a hair-line shrinkage crack
develops.
36. Fig. 1C. This joint, in common use, can provide positive
thickness of mortar jointing, but little resistance to transverse s.ear
(the mortar, if any, in the horizonTal jointing surface is in tension).
Farther it is a sthctually fragile edge detail, readily damaged in transit.
37. ,E This joint provides positive shear resistance
to offsetting of adjacent slabs, even after shrinkage cracking of mortar.
It requires use of side-retracting edge-forms in production. It is a rigid
joint, in common with all those discussed above. However, by painting
the joint suriaces with bitumen (about one millimeter in thickness) before
mortar pointing, a small degree of rotational flexibility can also be
provided, while retaining resistance to shear. More sophisticated join+s
of this type can be used, providing greater rotational flexibility and
more positive bituminous seal.
38. i E. The most critical joint in expansive soils is the
botto longitudinal joint. A joint providing rotational flexibility,
resistance to displacement of either bottom or side tile with respect to
the other (kicking out or up) and positive flexible seal is shown in 1E.
39. It is emphasized that such joints require care in slab manufacture.
D- -packing of a finer-aggregate richer mix around the edges of the mould
before regular placement of the remainder of the mix is desirable. The joints
need to be simple, not readily damaged, but functional in the respects
discussed. The simple square joint is not adequate for a quality lining in
expansive soils.

Dear Gaby,
UP Tubewells I & II
I visited Lucknow in connection with preparation of UP IIon 28th and 29th September 1981.
A summary of pr eso on UP I up to and August is attached.The number of wells in operation was 57, and number of wellsdrilled and developed was 314.
Progress at the moment is slowed by monsoon weather and somedelay in supply of PVC pipe. However the latter problem will beremedied by delivery of an additional extrusion machine to WAVINnext month. Some teething problems with hours-run moter and controlblack box are being overcome. Completion of UP I is now projectedfor September 82 but completion of drilling 500 wells is likely byend November 81. COUP is now formally requesting extension of theproject to 640 wells through "savings" largely due to the originalprovision for contingencies and price escalation not being invoked.
Although one of the O&M Divisions which should provide supportto cultivators and monitoring has belatedly been sanctioned, only afew officers have been posted and these without associated staffand vehicles. Agriculture Department support consists of second-ment of three officers only, to Irrigation Department. These arepreparing leaflets on crops and practices for the coming rabi season,for distribution to cultivators in lieu of agricultural extension.Irrigation Department also proposes to establish one demonstrationplot (on a selected cultivators farm) near eacb tubewell and toprovide inputs at no cost, particularly for UP II. This will requireparticipation of at least 50 agricultural officers, presumably ondeputation from Agricultural Department.
In discussion with the State Minister for Irrigation (the fullMinister was in Delhi) it was put to him frankly that the systemproposed in the U.P.I. project document for extension and monitoring
2
2
had failed, due to almost total lack of support by the AgricultureDepartment and the Secretariat and that the mission would recommendto Bank that for UP II simple assurances should no longer be sought,but that disbursement should be made conditional on satisfactorysupporting services for each well.
It was agreed with the C.E. Tubewells that his three agriculturalofficers should give pre-season extension advice and follow veryclosely the rabi season performance of three wells on "dedicated"power lines (un-rationed), representing anticipated UP II "withproject" conditions. Functioning of the rotational system andoperation at the cultivator level will'be monitored, and cultivatorson each outlet valve will be interviewed. This is much reducedin scope from the action envisaged in the UP I project document,but is as much as can be achieved without the sinews suggested forthe UP II document.
The UP II project report of April 81 prepared by the State isbeing cleared by G.0.I. for formal transmittal to the Bank. Theprincipal components will be:
New Tubewells 4,200Modernization of old wells 180Pilot developments, including
sprinkler installations 100(or equivalent of 4 erores)

OFFICE MEMORANDUMTO: Mr.
DATE: June 25, 1981
FROM: J. C. 'Ryan and K. echoutek, ASPjW
(through Lamson- cribner, Chief 2
UBJECT: INDIA - Upper Ganga Canal Moder isation ProjectjPiJA
SUBECUttar Pradesh Tubewells Il Project
Messrs K.G. Jechoutek and J.C. Ryan of ASPEW (under terms of
reference dated 4/28/81), together with Mr. Don Campbell of FAO-CP, travelled
to Lucknow to discuss the power supply issues of these projects with
representatives of Uttar Pradesh State Electricity Board (UPSEB) in a meeting
held on May 13, 1981. The meeting was chaired by Mr. A.K. Gupta, Member
(Technical) of UPSEB. Also present were Mr. S.K. Mathur, Chief Engineer
(Hydro), Mr. S.P. Mathur, Chief Engineer (RE), Mr. J.C. Gupta, Additional
Chief Engineer (Planning), and representatives of the UP Department of
Irrigation.
This discussion was prompted by the need to ascertain the ability of
UPSEB to provide reliable supply to pumps under the above projects, including
an examination of the option that the tubewells should have independent,
dedicated power lines separate from UPSEB's existing rural system.
Construction of what might become a duplicate system could be a non-optimal
solution. On the other hand, a case might be made for separate feeders since
such a system could be given priority in times of power rationing and load
shedding, the priority being justified by the need for continuous reliable
power for large State tubewell punps which are required to be operated for
more hours per day than smaller private irrigation pumps. (Without power,
the investment in pumps would be wasted).
Power supplies in Uttar Pradesh have been inadequate in recent years,
and in the year ending March 1981, which saw an unprecedented drought,
rural
feeders were never energized more than 9 hours per day on average,
and in the
worst months were down as low as 3 1/2 hours per day. The State Electricity
Board's forecasts indicate that they expect deficits to continue indefinitely
(Annex 1). It must therefore be assumed that ordinary rural feeders will be
subject to load shedding for many years to come.
At the meeting UPSEB confirmed their statement, previously made to
the World Bank Composite Irrigation Project Mission on May 1-2, that they
would be willing to build feeders dedicated solely to the purpose of these
two projects. The feeders would come direct from 132 kV substations, which
are not rostered and hence are energized at almost all times. Supply would
normally be available on these feeders for 24 hours per day. Augmentation
wells could therefore pump continuously when necessary.
In the case of the direct irrigation tubewells (DITs) in UP TI,
supply could also be provided 24 hours per day but the CEB would prefer to be
able to shed them over the peaks for say 4 hours per day. UPSEB foresaw no
political or other difficulty in giving such preference to power supplies for
public irrigation facilities.
-2-
The full capital cost of special works such as these feeders wouldhave to be met by someone other than UPSEB; the SEB would own, maintain andoperate them. (Estimating prices suggested by UPSEB were Rs 20,000 per km for11 kV and Rs 55,000 per km for 33 kV line). Assuming that the loads arereasonably close to the transformer, an 11 kV feeder will usually supplyabout 1,000 kW of load, and the average load of a DIT would be about 12 kW.It should be noted UPSEB's position may not consider overall systemeconomics; it requires that the projects pay for the needed facilities andthat UPSEB is "kept whole" financially.
The DITs to be installed under UP II number 5,000. They willprobably be in clusters of 10-20, but the clusters will be widelydistributed. It will thus be necessary to examine on its own merits thequestion of feeding each cluster, when its location is known. Where acluster would be close to an existing feeder, the option of using thatfeeder, perhaps with appropriate improvements, would be examined. UPSEBthought that in most instances this would not be a satisfactory solution, asexisting feeders are usually leavily loadod, and owing to frequent faults andslow restoration they often suffer considerably more outage time than eventhe rostering scheduling would suggest.
On the other hand, UPSEB might in some cases wish or be virtuallycompelled to connect certain other consumers to nominally dedicated feeders,where there was no other reasonable means of supply. Although eachadditional connection will increase the probability of outage on a feeder,some examples of this would no doubt have to be tolerated.
It should be noted that the case for separated dedicated powerdistribution rests on the desire for a reasonably reliable supply to servethese specific consumers and assumes that these consumers will have priorityover most other consumers. The benefits of such a dedicated system will bediluted or lost if the project's government-owned tubewells are not grantedthis priority over other consumers, including private agricultural consumers.
For the operation of essential canal water control structures on theUGC, dedicated feeders could similarly be provided, but these could still notguarantee an infallible supply. For absolute reliability, standby energy insome form will have to be provided. It might take one of a number of forms,such as direct drive engines, engine driven generating sets, compressed airvessels, elevated water storage tanks, or human energy.
It would appear that the suggestion of returning the hydro stationsthat are disposed along the canal to the control of the Irrigation Departmentwill make little headway. There are eight of these stations, ranging in sizefrom 500 kW to 20.4 MW, and they are spread over a distance of 150 miles.They form a small but not insignificant part of UPSEB's reliable generatingand transmission, and men would have to be seconded from UPSEB to do it.
-3-
Since UPSEB are unlikely to be sympathetic to the scheme, its chances ofsuccess appear slim. UPSEB was however receptive to the suggestion that 11kV feeders, dedicated to supplying power either to augmentation wells and/orto canal water control structures, might in some instances be providedconveniently and economically by taking them right off the 11 kV busbars atthese hydro stations.
We would recommend:
(a) As soon as points at which supply will be needed are known,UPSEB should be approached and asked to investigate each oneof them to determine the best way of feedingit, taking due cognizance of the possibilityof using existing feeders, with improvements if necessary.Consideration to feeding a limited number of other potentialconsumers from the new feeders may also be given.
(b) Where UPSEB's study indicates that a dedicated feeder would benecessary to provide an acceptable level of reliability, theIrrigation Department should evaluate this in comparison withany alternative available such as the provision of a larger pumpwith storage.
(c) At canal water control structures where power for operation isessential at all times, standby energy sources must be provided.

2. Construction of UP Tubewells I is progressing satisfactorily, after alate start due to procurement problems. Operation and Kaintenance Divisionshave not yet been fielded, but are expected to be in position by end June.Mr. Aw Yong inspected eighteen of the twenty-one wells in service at thetime of the Yission, and reviewed agricultural performance. 1Agricultural support remains conspicuously lacking, also monitoring ar!review functions. These subjects were taken up with the Secretary ofIrrigation and Director of Agriculture, also with the Iinistry of Irrigationand the Department of Economic Affairs in New Delhi. They will also beunderlined in the report of the formal supervision mission (J. Cunninham,D. D. Taneja (Bank), D. E. Campbell (CP) ). Copies of the CP TechnicalSupervision Report of 23 Vlay are attached.
3. A critical factor in the performance of UP I and prospective UP IIwells is the supply of electric power, at present available for less thanseven hours per day. In an unexpected change of position, the StateElectricity Board has now offered to provide an unrationed supply toproject wells via restricted access ("dedicated") feeders. This willconsiderably enhance agricultural development in the tubewell areas.A copy of aCP letter to Reidinger/Tibor on the subject, in relation to
... both UP Tubewells and Upper Ganga 11odernization projects is attached
4. With regard to UP II, preparation is proceeding satisfactorily,in expectation of pre-appraisal in November 1981 and final appraisal inFebruary/iarch 1982. An issue of interest is the relative role of"direct irrigation" and augmentation wells (discharging into canals)in UP. This question, and the status of preparation of UP II generally,are discussed in the memo of 23 May to G. Tibor, copy attached,] 2/
5. A possible modification to the hydraulic control system for theUP I and II wells, retaining the automatic feature but facilitating morerapid construction, was developed by the Mission and proposed to theState for early installation on a trial basis. The subject is discussedin the letter of 30 Yay, CP to B. P. Goyal, Additional Chief Engineer.A copy is attached.

6. The Indian manufactured version of the Italian machine forproduction of channel lining components is now working very satisfactorily.
The order for twelve additional Italian machines is still being processedby central Government.
7. At a meeting with the CAD Comissioner in Bombay the Yission.proposed that GOI now take up production of slabs for lining of largerchannels, the slabs having edge configurations which provide both flexibilityand sheer restraint in the lining. A drawing of equipment for productionof such slabs was later forwarded to the Commissioner, with the suggestionthat it be fabricated locally (see letter of 30 May to P. R. Ghandi, copyenclosed j).
Gujarat II
8. At the request of the Bank, the !iission combined discussion of theDamanganga project pipe distribution system with participation in a Banksupervision of channel lining in the Panam and Marjan projects of Gujarat II.The latter subject is discussed in a separate Bank mission report, butwarrants comment here. In the Panam project very poor quality constructionand early deterioration is being encountered both in cast-in-situ maincanal linings, and in cement-mortar tile linings of watercourses. Theproblem in both cases is due, in part, to use of inadequate quantities ofcement, largely through lack of supervision of the work of contractors inremote construction areas. In the case of watercourses a lightweightpressed cement-mortar tile is being used, placed upon in situ trowelledmortar. With inadequate quality of the latter the tiles become readilydislodged and widespread failure of the lining results. A more satisfactorylining would be achieved in the circumstances by use of machine-producedintegral lining components, or in larger channels use of slabs withconfigured edges of the type discussed above (aharashtra). The letterof 30 May, 1981, to Shankar Iyer, Irrigation Department, Ghandinagar,discusses the latter technique; copy attached j.
Subernarakha Project (Bihar and Orissa)
9. This project, in which the CP was earlier involved, has been underpreparation for the last year by consultants WAPCOS and the two States.The position was reviewed at the meeting of Bank and GOI referred to above,with particular regard to construction programme and budget. CP is nowrequested to proceed to appraisal (jointly with Bank) by year end. Ajoint preappraisal mission is scheduled for mid-July. 2/-

10. Continuation of technical assistance to Kerala (Kallada project)
which was included in the Mission's TOR was deferred, pending further
Bank review of the project, but is likely to be taken up again shortly.
11. The two UI1P projects (channel lining and drainage of "black-cotton"
soils) in which CP has taken initiative in preparation are now unlikely
to be operative before year end. The FAO Representative was asked to
assist the Departments concerned in finalizing processing. Meantime
work on channel lining development will be pursued through other channels

The above subjects were diecussed in Lucknow with State Electrict.tyBoard on Iay and 12 Kay. Messrs. Rodger and Reidir-er participated inthe first meeting, and 1essrs. Jachoutek and Ryan (AM:.I) in the second.Messrs. Vijendra Siugah (UGC) and B.P. Goyal (UP I and II) participated inthe meetings, also WAPCOS and C.P.
The issues discussed were the following:
(a) Reliability of power supply for operation of hydrauliccoatrol structures on the U.G.C. principal canals
(b) Power supply for U.G.C. tubewells
(c) Power supply for UP 11 tubewells
With regard to the first item, central questioas were
- Whether virtually 100% reliable supply of the relativelysmall quantity of power required for U.G.4. gate operationcould be assured, either by providing a secia. feeder linealong the length of the canals or otharwi e
- Whether reliability of supply froi such a 1 :e would bereduced by also employing it for prower su l:, to U.G.C. wells

OFFICE MEMORANDUMTO: Mr. G. J. Tibor, Chief, ASA DATE: April 1, 1981
FROM: Richard B. Reiding ASPAC
SUBJECT: INDIA - Upper Ganga Irrigation Modernization Project- Uttar Pradesh Tubewells II Project- Coordination with ASPEW
1. Messrs. K. Jechoutek, J. Ryan (ASPEW), W. Rodger and R. Reidinger(ASPAC) met on March 26, 1981. The purpose of the meeting was to discussbriefly the electric power problems related to the Upper Ganga IrrigationModernization Project and the UP Tubewells Project.
2. Availability of secure electric power is of major importance toboth projects, which are both scheduled for appraisal in mid-FY82. Powersupply issues differ somewhat for the two projects.
Power Situation in Uttar Pradesh
3. Despite its enormous hydropower resources and some 3,500 MW ofgenerating capacity, the State of Uttar Pradesh (UP) at present facessevere power shortages which will likely continue or worsen in the foresee-able future. Peak shortages at present are estimated at about 25% ofpotential demand (unrestricted by power cuts). On an annual basis, theshortage amounts to some 10% of demand. As a result, power cuts androstering are frequent, and even supplies based on scheduled rosteringsare often interrupted. Public tubewells in UP can only operate about8 or 10 hours a day due to both scheduled and unscheduled power outages,and that amount of time is often unreliable and at odd hours. By 1985/86,the peak capacity shortfall is expected to worsen, reaching about 30% ofpotential demand.
Upper Ganga Irrigation Modernization Project
4. As presently conceived, the Upper Ganga project would include atotal of about 2,000 cfs in augmentation tubewell capacity, or anywherefrom approximately 400 to 1,200 tubewells depending on size. In generalgroundwater resources throughout the Upper Ganga command, particularlyto the north, are excellent. The augmentation tubewells will requiresubstantial amounts of power, and whether power is available 8, 12 or24 hours a day, or only at night, will affect canal design. Location ofaugmentation wells would be determined by several considerations, includingavailability of groundwater, aquifer characteristics, canal locations, andcanal system management requirements. The total amount of augmentationcapacity to be included at this stage is quite flexible, and could bereduced substantially if the requisite amount of dependable power is notavailable.
Mr. G.J. Tibor - 2 - April 1, 1981
5. Perhaps more important than power for augmentation wells is powerfor system regulation. Although quite small, power needed for canal
operations should be essentially 100% reliable if the system is to dependon electric power to mechanize water regulation. The system has some
40 MW (20 MW firm) of generating capacity on the main canal, which
reportedly (but not assuredly) could be diverted from the grid (ascaptive power) to provide secure power for canal regulation, and tosome extent for augmentation well'.
UP Tubewells (II) Project
6. The UP Tubewells (II) Project would finance construction of some5,000 new State tubewells throughout the State. UP has about 16,000 large,State-operated tubewells already in operation. Generally, project tubewellswould be in blocks dispersed throughout the State, located in areas presentlyout of canal command.
7. The proposed project is patterned after the ongoing UP TubewellsProject which is financing some 500 new tubewells over a two-year period.That project is progressing satisfactorily. However, a major problem forproject tubewells is lack and unreliability of electric power. Power cutsand unscheduled outages severely curtail operating hours and reduce operationalefficiency in terms of tubewell management, irrigation and agricultural pro-duction.
8. Power problems affect essentially all public tubewells in the State.The increase in power demand from the 5,000 new tubewells would amount toperhaps 4% of total peak (restricted) demand. However, because they arewidely dispersed (unlike the Upper Ganga case), public tubewells present anadditional problem in power service and distribution, in addition to theavailability of power itself.
Arrangements for Reconnaissance of UP Power Situation
9. ASPEW plans to have a power mission for another project in the fieldin India by approximately May 10. 1/ Mr. Don Campbell (FAO-CP) who is workingon the UP Tubewells II preparation and is also familiar with Upper Ganga, willbe in India from about May 1-20. Arrangements for the ASPEW mission andMr. Campbell to overlap for discussions on the power problem have been made.In addition, if the ASPEW mission as finally planned shifts forward by a fewdays, I could perhaps overlap with them also. (My present plan is to be inIndia until May 5).
1/ Latest plans are for Mr. Jechoutek (Economist) to arrive on May 8 andMr. Ryan (Engineer) on May 12.
Mr. G.J. Tibor - 3 - April 1, 1981
10. Several key topics should be examined by Mr. Campbell and the ASPEWmission, and discussed as necessary with GOUP, SEB, the Irrigation Departmentand WAPCOS (Upper Ganga preparation consultant).
(a) Off-peak power availability-the amount of off-peak poweractually available, and its reliability (e.g., poweravailable on an uninterrupted basis every night).
(b) Distribution system problems-the capability of thedistribution system (perhaps by region) to deliverpower to tubewells without unscheduled outages and atdesign voltages, assuming off-peak power is available.
(c) Dedicated power line and service for Upper Ganga--securepower is essential, at the very least for canal operationsand telemetry.
(d) Role of Upper Ganga captive power--whether the IrrigationDepartment should take back from the grid captive powerand its distribution for canal operations and augmentationwells, or whether an arrangement for secure power in likeamount from the grid can be provided to the Upper Gangacommand.
11. The first point--the amount of off-peak power actually available--isof primary importance at this stage. It would likely affect the design sizeof both augmentation and direct service tubewells. It may also affect theneed to provide for more night storage, either from larger canal capacitiesin the Upper Ganga Project or from day-night tanks in UP Tubewells Project.
12, Mr, Reidinger will introduce these matters briefly in discussionswith relevant government officials during his visit prior to the ASPEWmission's arrival. The ASPEW mission (with Mr, Campbell's assistance) willbriefly examine the UP power situation as related to the Upper Ganga andTubewells Projects, giving particular attention to the key topics above.Depending on the amount of data available, the mission will also examine inmore detail how GOUP/SEB plan to cope with power supply constraints in termsof these two projects. Following the mission, they will communicate theirfindings to ASPAC on the present and future power situation in UP, GOUP plansto deal with it, and a set of recommendations on how best to proceed on the twoprojects with respect to power supplies.

CONJUNCTIVE USE OF GROUNDWATER AND
SURFACE WATER IN THE -GANGETIC BASIN
Study of Water Distribution Systems
Terms of Reference
The macro-relationships between surface water, groundwater, and
recharge in the Gangetic Basin are currently being explored through mathe-
matical modelling. The study discussed herein will be directed at the
related question of distribution and utilization of groundwater in associa-
tion with canal supply. It will cover "conjunctive use" in the broad sense,
ranging from systems of mixed supply to systems of separate surface and
groundwater supply in adjacent areas.
The study is intended as background to two major irrigation devel-
opments now in course of preparation in the Gangetic area, the Upper Ganga
and the Uttar Pradesh Tubewells (Stage II) projects.
The approach should be at the conceptual level initially, covering
both present and future levels of development. Alternatives for immediate
development should subsequently be evaluated in more detail. The study should
be completed by the end of June 1981.
The attached random notes on the subject in question may be useful
background to the study.
THE GANGETIC BASIN
Study of Water Distribution for Conjunctive Useof Surface and Groundwater
Preliminary Observations
1. The systems which will be in operation in the basin in the immedi-
ate future are the following:
- The existing surface water distribution system,
with such extensions and modifications as may be
introduced through the Upper Ganga project;
- The large number of private tubewells and open
wells currently operating in the area;
- The existing 15,000 "Direct Irrigation" public
tubewells in the basin, and the 5,000 new DIT wells
to be constructed under the UP II project, which
will serve a further 400,000 to 500,000 ha by 1988;
- New Public tubewells to be constructed under the
Upper Ganga project. The manner of their associa-
tion with the surface water system is to be determined.
To what extent private wells will continue in operation as the public well
program expands is an issue in itself and is discussed further below.
2. The alternatives available for operatio% of the proposed Upper Ganga
tubewells include the following:
- Delivery into primary or secondary surf'ce canals;
- Delivery into tertiary or quaternary surface canals
(minors or watercourses);
- Operation independently of surface systems, but serving
areas adjacent to those supplied by surface canals.
3. The Upper Ganga canal system was designed to supply water at a
very low intensity of irrigation in the dry season. Although distributaries
normally serve the whole command, the area between adjacent distributaries is
not entirely served by minors.
This situation raises a number of questions:
- Should the Upper Ganga project tubewells supplement
supply to those areas already served (although in-
adequately) by surface canal supply, or should they
be located in areas commanded by distributaries but
not served by a minor distribution system? In the
latter case would the minor system be extended into
those areas or would the tubewells operate indepen-
dently of canal supply?
- To what extent will the areas referred to be served
in any case by planned UP II tubewells, which will
be distributed across all Districts of the State?
What would be the distinction technically and admini-
stratively between UP II tubewells and Upper Ganga
wells in suzh areas?
- In view of the low canal irrigation in.ensity in the
dry season, it is necessary to rotate operation of
minors and distributaries in that season unless they
are fully lined. Delivery from a tubewell into a
channel which is operating rotationally has the
disadvantage that the tubewell could not be operated
continuously. An exception is a tubewell or a group
of wells of sufficient capacity to supply at a rate
approaching the capacity of the minor, in which case
the minor operates continously in the dry season but
primarily on groundwater 1/.
- Power rostering will presumably continue into the
foreseeable future. If Upper Ganga wells are to
discharge into and contribute a substantial propor-
tion of the flow in minors or distributaries in the
dry season (e.g. one-half) power rostering would
cause a major, and not entirely predictable, variation
in rate of supply to the minor. Pondage might need to
be considered. If the wells discharge into main or
branch canals, power rostering is likely to be less
of-a problem as the proportion of tubewell supply to
canal supply is less, canal storage is greater, and
the main and branch canals are in any case equipped to
operate at a considerable range of discharge.
- To avoid simply re-circulating groundwater, Upper-Ganga
wells should not be located near to unlined canals.
The current extent of lining of main, branch, distri-
butary and minor canals, and future plans for lining,
consequently has a bearing on location of wells and the
order of canal into which they will discharge.
- The introduction of tubewells into the Upper Ganga
system on a considerable scale will represent a
major up-grading of service. Introduction of more
efficient distribution to the farm is likely to be
warranted. Use of buried pipe systems, chak pondage,
etc., should be considered in the context of joint
use of canal and tubewell supply.

SUBJECT: INDIA - Upper Ganga Canal (CCC) Irrigation ModernizationUttar Pradesh (UP) Prciect Preparation
This is an answer to your question on the desirability ofplanning for an exclusive power transmission grid for equipment which mightbe included in the UGC irrigation modernization program. As we discussedon the telephone, I've discussed the proposed project with W.G. Rodger andoffer the following comments.
As I understand, a part of the project is-to provide largedeep wells with electric pumps which would pump from deep aquifers andsupplement the water available from the Ganga by providing more water into
the canal system. Basically the big pumps would pump into the overall
irrigation canal system. Although final plans must await further study,Rodger indicated that there might be as many as a thousand pumps spreadover a large area and that such pumps might have'general capacities in the400 cubic meter per hour range (total electrical load might be of the orderof 50 megawatts). Rodger also indicated that for the supplementationscheme to work, the pumps would have to be provided with as reliable asource of power as possible and he would expect that the pumps would haveto be operated in the order of 8-10 hours per day. He also consideredthat the present electricity distribution system did not have adequatereliability and that it would not be worthwhile to put a large investmentof electricity consuming equipment in an area where power supply was notreliable enough to guarantee the efficient use of such equipment. Theseare valid observations and conclusions.
The objective of the augmentation program is to provide watcrto the canal system. We are then concerned with the total system to providethat water which if done with electrical pumps includes the power generatingfacilities, high tension transmission lines and substations to provide pover
C over the large area involved, low tension 33 and 11 kv distribution linesfor smaller geographic areas, and finally the electrical facilities andmotors at the pumps. Since the area involved where the new pumps would belocated also corresponds to areas where there are existing or planned ruralelectrification systems for other pumps, small industry, and villages, it isalso desirable to consider the total electrical system. It would probablybe anti-economic to have two wires down the road, one for the existing orplanned normal rural electrification system and another for the UGC augmen-tation pumps.
Overall reliability is the key concern of the electricalsystem if the new pumps are :: :e justified, although It should be recog-nized that there are tradec.::s between reliability, system costs, and consumerlosses due to Tower interr-=:icns. In general, the overall reliabilityof a system basically starts with the generators and goes through the high-
Mr. Wilfried P. Thalwitz - 2 - March 16, 1981
tension transmission to the lower tension distribution. If, as is proposethe electrical demand for the augmentation wells is to be satisfied by thegenerating stations and high tension grid of the UP State Electricity Boaru(UPSEB), then the reliability of the UPSEB generators and grid is relevant,regardless of whether there is a separate distribution grid for the augmer-tation well motors or not. (An alternative might also be conceived thatthe augmentation well electrical demafids would be provided'for by a separaegenerating system but this would indeed be anti-economic since it would putthe electrical system for the pumps in total in parallel with the UPSEB;one would have to have generating stations, transmission lines, and distri-bution lines as a parallel system in order to be isolated completely.) Itmay therefore be necessary to improve the reliability of the UPSEB's genera-ting/transmission system or to consider that reliability when consideringoperation of pumps.
As regards the final distribution system at the 33 and 11 kvlevel, the reliability of this portion of the system is dependent on itsdesign and operation, on acts of God (lightning and lorries striking poles)and on general overall maintenance. A separate system for the augmentationwells would have the same risk factors to consider reliability-wise as thepresent system.
We might also wish to consider whether or not it would beeasier or more efficient operations-wise if the electrical system werebuilt or operated by the UPSEB or perhaps by another authority. Ingeneral, the same problems must be faced regardless of who builds oroperates the system. Further, although certainly the UPSEB might not bea model of efficiency, it is highly questionable whether a new authorityor one without experience in construction and operation of power distribu-tion facilities would be more efficient and in fact it might also be prognosedthat there would be a learning curve for such new authority (or new respon-sibility for an existing authority) and more difficulties might be encounteredthan at present. Further, since a fair amount of the operation depends onmaintenance, it would be anti-economic to have two sets of operators andmaintenance crews spread around the state, the one to maintain the UGCaugmentation system and the other to maintain the UPSEB system.
Perhaps we should consider the alternative of working withand improving the present power system in the UP in the augmentation wellarea, to provide not only economically reliable power for the UGC augmen-tation pumps but also to provide adequate power for all the other consumersin the areas affected. To this end it would be desirable to review thepresent and planned RE system in the general UGC augmentation area, tointegrate this with the expected demand for UGC augmentation, and to developan overall system which would provide for all consumers in an integratedway. Basically, the UPSEB should be informed on the potential power demandfor augmentation (50 Mw is a good sized lump), and the UGC authority and theUPSEB should work together in overall system design. Based on this, aproject or subproject for electrification would be developed. To construct
Hr. Wilfried P. Thalwitz - 3 - March 16, 1981
an overall satisfactory system would probably be no more difficult and
might be less difficult than to construct a separate parallel system, and
overall it would be more cost effective.
Harking back to my memorandum of March 11 to Roger Rowe, this
project provides an ideal opportunity to integrate the interests of an
agricultural power consumer and the power supplier. First, the overall
distribution system should be developed reasonably optimally. Further,
in developing the distribution system and its voltage levels, a balance
will need to be struck between line lengths, voltage reductions in trans-
formers and sub-voltage levels if any, and motor characteristics. Next,
certainly the motors should have power factor correction. Lastly, this
project would offer an ideal opportunity to introduce time of day use and
arrangements should be made for the agricultural pumping to be done during
those periods of the day when power demand on the total UPSEB system is at
its lowest, say from 10 p.m. to 6 a.m. This is especially important in
India's Northern Region where there is a projected 10-15% shortfall in
generating capacity (during peak periods) as compared with presently
envisaged demand (probably excluding this project) throughout the 1980's.
ASPEW will be happy to work with ASPAC in this whole regard.
Other institutional matters may arise such as how funds should be channeled
to UPSEB for the power component of the project, but I am sure this will notrepresent a stumbling block.

leaflets on cultivation and irri ation practices to each fa erreceiving water from the project, in e aosence of active fieldextension by the Agriculture De rt:ment in tae project area.
A detailed progress summary is attached to "P 'anagementand Bank copies of this report.
A second stage project, UP Tubewells II, has now been formallyincluded in the 1981782 Bank lending prormme. Governent of UP hasprepared a project proposal which includes 5,000 new tubewells,reconstruction of 5,000 existing wells and addition of buried pipedelivery systems, and a small number of sprinkler systems. The numberof wells to be reconstructed will probably be reduced for budgetaryreasons to a much smaller number. However, total cost of the projectis likely to be of the order of Re 240 Crores ($300 million).
Bank has asked CP to coordinate preparation of UP II and toparticipate in appraisal, which is tentatively scheduled for end-'81.The approach to be used in economic analysis of UP II and the extentof supporting data which will be available frorf UP I will be digcussedwith Bank in early Iarch. A further visit to the project area isplanned for late April.
Maharashtra I
CP designs for hydraulic control structures fabricated fromcomponents produced on the two Italian machines in operation in theproject area were discussed, and arrangements made for pilot fieldinstallation.
A locally manufactured extrusion machine, based on the Italianoriginal, was on trial in the project area. It is expected that certaindesign deficiencies encountered in initial operation will be overcome.In the meantime the State is procuring twelve further Italian machines.A locally manufactured "egg-laying" type of extrusion machine is alsoin operation in the project area.
Due to the very unfavourable shape of the local crushed basaltaggregate, and consequent permeability of mix, a supplemental mortarwash is being applied to linings produced in the Aurazgabad area.Further work on mix design and mortar treatment is in progress.
Kallada Project (Kerala)
A notable feature of the proposed Kallada project is theapplication of buried pipe systems for water distribution to gardenlands on valley slopes. The pipe systems are supplied from open minorcanals, and each typically serves some 5 ha to 10 ha. CP is providingtechnical assistance and staff training, and on this occasionparticipated in a Bank post-apprFisal mission.
One ins,,allaticn, constructed in acc-rdance i CP suestions

made during the previous (November '80) visit, was operating satie-
factorily with temporary water supply during the mission. Comparativeestimates of cost of buried pipe and open channel systems indicatethat in the circumstances of Kallada project buri-ed pipe may be used
for valley slopes down to l4o.
A working paper on "Water Distribution below the Canal Outlet,Kallada Project", dated February 13, '81 was prepared for the appraise.1
mission. The paper presents design details and cost estimates.Copies are on Bank and CP files.
Damanganga Project (Gujarat)
In anticipation of future conversion to irrigated gardenlands it is proposed to install buried pipe distribution systems in
a proportion of the project area currently under rainfed fodder production.CP is providing technical support in system design and staff trainingfor this on-going project.
The project had prepared topographic surveys as a basis fordiscussion of typical designs and cost estimates; and development of
criteria for application of pipe system vs open channel. The topographyis distinctly different from that in Kallada project, combining gentle
macro-relief with steeply-sloping micro erosion pattern. Designs of
pipe systems for a number of typical topographic situations were worked
out and will be discussed with Bank in early March, following which
specifications for application of pipe systems, vs open channel, anddesign details will be pursued further with the State.
Subernarekha Project (Bihar/Orissa)
CP and Bank activity in this project has been in abeyance since
early 1980 when Government of India directed that identification and
preparation of irrigation projects should be carried out by States with
assistance of local consultants, and that Bank (and CP) involvement shouldbe restricted to appraisal. In GOI/Bank discussion of the projectpipeline in February '81 this restriction was, in effect, lifted.One immediate result was re-involvement of CP in Subernarekha project.The project is now tentatively scheduled for appraisal end '81.
The mission reviewed the state of preparation with consultantsWAPCOS. An issue which still remains undecided is the budgetaryallocation to the project by each State. As this question appearsunlikely to be resolved until the stage of final appraisal, it may be
desirable to present the project in such a manner that the scheduling ofconstruction of the various separable components (five reservoirs and
a number of canal systems) may be varied during appraisal negotiations,and financial and economic implications imediately determined. Strateayin project presentation will be discussed with 3ank during the second
week of !arch, and with WAPCOS sh'orCtl th reafter.

U.P. Tuewells - Technical Supervision, February 1981
I visited Lucknow on 1st and 2nd February for field inspectic'
and discussion of UPI and preparation of a second stage project. Asummary of progress on UPI up to end-Jamary 1981 is attached. Well.drilling (204 completed) is now approaching schedule (244 planned for
end Jamary). Installation of PVC pipe is well behind schedule due to
delay in awazd of contract but the latter was finalized on 14th Januaryand deliveries have already oommenced.
Procurement delays still affecting progress are compressors sAi
rigs (one only yet delivered), pumps and electronic control units. Thetwo 0 and M Divisions have not yet been sanctioned in spite of pressurefrom DE; in the meantime operation is being carried on by ConstructionDivisions. Only one agricultural supervisor has been attached to the
Irrigation Department.
Nine wells are now in service. The first of these to go into
operation (29 November), and the only one which has been in service throughmost of the 1981/82 rabi season, has given a very creditable performa-ice,136 acres of crop being irrigated out of a total net command area of
284 acres. The considerable proportion of potatoes in the cropping pattern
is noted, the remainder being principally wheat and mustard. Rate of
delivery to the field with the new delivery system is judged by theIrrigation Department (based on time taken to irrigate an acre) to beabout twice that achieved with the previous system.
In view of the delay in sanctioning and fielding of Agricultural
Supervisors the Irrigation Department, with the assistance of Agriculture,
proposes to issue pamphlets to all cultivators being served by the project,showing in simple pictorial form cultivation and water management practices.The Department was advised to obtain from Andhra Pradesh copies of theexcellent leaflets on agriculture and water management issued by thatState, as a guide to preparation of similar notes.
As field staff training takes up a considerable amount ofstaff time, the Irrigation Department has asked for sanctioning of
a separate Investigation and Planning Division to take over training, andalso monitoring which is not yet fully cperational due to lack of staff.
The Department has now produced a "Project Summary for World Bank"for a second stage project covering 5000 new tubawells, modernization
of 5000 old tubewells (including construction of buried pipe deliverysystems), and. 100 new u ocwlls with sprirklor systems (in the Chambal
ravine area). Estimated cost at present price levels is stated to be
Rs. 345 crores (U0445 million). U.P. Secretariat has already advisei the
Department that this exceeds Sixth Plaz buiet for public tubewells
-2-
(believed to be some Rs. 230 crores including wori on the first stageproject). The ammber of old wells to be modenized is consequentlylikely to be scale down.
The project will be discussed with 0.0.I. .on 6th Februazy.
Two central issues in appraisal will be the effectivenessof treatment of wells with reduced discharge (a proportion of the wellsto be modernized will be chemically treated, and cthers will bere-drilled), end assessment of the increment in production to beexpected from modezization. The latter question was discussed withthe Department and U.eD*E*S.Ce0., contractors for the Stage I benchworksuvey.
uprther C.P. action on the second stage project will iependupon the outcome of GOI/GOUP discussions on 6th February, and reviewi:th Bank.

WATER DISTRIBU)TION BE0W THE CANAL OUTL'
Desig Basis and Cost Estimates
Background
Following on the visit of the appraisal mission the design ofthe distribution system below the outlet was discussed in further detailith Irrigation Department staff in December. Two installations have beenconstructed in accordance wit6h layouts agreed .upon at that time., Oneof these was in operation during the February visit, with temporary watersupply, as the main canal was not yet in operation.-
The following notes on design basis represent minor modificationand further development of the designs developed in the December visit.The cost estimates are based upon unit rates for construction and procurementas at January '81.
Design
The principal factors determining the form of the distributionsystem are the very irregular micro-topography, the high degree ofexisting development of the area, and the very high value of land. The areais densely planted with coconuts and other perennials, generally in smallbunded plots laid out in a most irregular fashion. Conveyance of waterfrom a supply point to a bunded plot by open channel would vary frompossible to virtually impractical, depending upon circumstances local tothe particular site. The difficulty is compounded by resistance of landowners to right-of-way for open channels in this densely built-uparea. From the technical view-point delivery to the plot (frequentlyan individual palm) by some form of flexible conduit is desirable inmuch of the area.
From the design viewpoint it is convenient to consider thedistribution sy:utem from the canal outlet in two portions:
a) A main stem, extending from the canal outlet down throughthe centre of the 10 ha (or other) outlet command.T'his has supply points at intervals down its length; and
b) Conveyance from the supply poi .t to the individinl fa-mand plot0 o
Where the main ztcn is a buried pipeline with valve-controlledoutlet hydrants a number of options are open for item (b), including:
1/ This is the eneral case. There are ezceptions, pa"ticularly where
- Open channel from hydrant to plot
- Flerible hose from hyr-t to plot
- Buried lateral zuplyin- flexible hose oropen channel
- Portable lateral supplying flexible hose oropen channel
Where the main stem is a lined open channel the only optiongenerally available for conveyance frcm supply point to farm or plot is aaopen channel.
In view of the =mber of options which it presents for conveyanceto the plot, either initially or in later improvement, a buried-pipemain stem is favored where valley-slopes are sufficient to make thiseconomically possible.
Of the alternatives available for conveyance from the outlet hydrantto the plot, buried laterals supplying short dowi-slope flexible hoses(or short open channels) is operationally the most ccnveient, but isthe most costly. As a buried lateral may be adadd at any time by -thecultivator or cultivators who desire it, it is not considered necessaryto make such provision in initial construction. The -alternative of flexiblehose from hydrant to plot is undesirable except for small narrow outletcommands, in view of the length required and size of hose needed for thatlength of cross-slope run (there being little natural gradient in thelateral direction).
The alternative recoomended for initial construction is the provisionof a single portable lateral extending either side of the main stem, withvalve-controlled spigots supplying flexible hose. Buried laterals may lalerbe substituted where required.
The lateral may be designed to deliver the full flow of the mainstem (successively to left and right side of the main stem), the spigotson the lateral being sized to deliver either the whole flow at one pointor half at each of two points. Alternatively the lateral may be designedto deliver half the flow of the main stem to the left and right sidessimultaneously, the spigot again being sized either to deliver the wholeflow in the lateral at one point or to deliver it at two points.
As the size of the lateral may be changed at any time (requiringonly a reducer at the hydrant), the option regarding lateral size andcapacity remains open.
The spigo-;s on the lateral are fonmed in short lengths of pipe whichare inserted at any joint between 6 m sections of the lateral, accordingto the location of the area being irrigated. Furthermore, spigot insertscan be provided of either full lateral flow or half lateral flow,interchangeably.
The portable lateral would generally be moved from one :yrart toanother once or zc.7 o t rai twice d&ily. The 6 ia sections are light
(about 8 kg each) End a lateral (one side of main stem) can be moved fromone hydrant to the next in about ten minutes.
Conveyance from the spout to the plot may be either by flexibleconduit or by unlined farm channel, according to circumstances.Flexible conduit (lay-flat pipe) is likely to be the most frequentusage. Where a holding is laid out so as to facilitate distributionwithin the holding by furrow irrigation a cultivator may prefer deliveryof the whole flow in the lateral at one point, by relatively large (90 mm)lay-flat pipe. The pipe would not require to be moved during irrigation,other than to shift from one spigot location to another, during whichprocess flow could be shut off. (Such large pipe would be positionedto run directly down-slope from a spigot to the point desired). Frequently,however, in the Kallada area, delivery by tube or hose to individual plotsor palms, will be required. This calls for a smaller hose which canbe freely moved while flowing. A cultiv'ator may prefer to. take delivery Vof his irrigation water in two such hoses which may be readily movedfrom plot to plot. As the time to irrigate one palm with a stream of 2 to3 litres/sec is about 15 minutes, the water being delivered into a smallbasin around the palm, an operator can handle more than one such hose.It ip not necessary. to hold the hoses continuously, merely to position themon the ground within the basins, .moving them-from basin to basin frome timeto time.
The capacity of lateral (full flow of main stem one side at a time,or half flow both sides simultaneously), and of spigots, to be providedinitially, should be discussed with cultivators in each outlet commandat the time of construction. As discussed above, however, the arrangementcan be changed at any time.
For consideration of distribution below the canal outlet the valleyslopes of the project have been divided into areas with side-slopes inexcess of 3% (some 20,000 ha), and a similar area with side-slopes lessthan 3%. The above discussion refers primarily to the area of steeperslopes. However, the comments on the difficulty of distribution to the plotby open channel apply also to a proportion of the area of flatter slopes.Just what proportion will be found only upon detailed investigation incourse of project execution. Although it has been assumed in initialpresentation of the project that the main stem in the areas of less than 3%slope will be in lined open channel throughout, it will probably be foundthat the desirability of piped or hose conveyance from the main stem tothe plot in part of that area will necessitate use of buried pipe for themain stem, where slopes permit. With regard to the latter criterion, a pipesize of 110 mm is probably the maximum which can be contemplated on economicgrounds. This could supply a 10 ha area with slope of 1.5% or above. %/As the cost of 110 in 2.5 kg/cm 2 PVC pipe is of the same order as the costof a lined open channel including value of right-of-way (the latter Rs. 10to 20 per metre) the use of pipe main stem with portable lateral may beassumed for half of the area with slopes less than 3% and for the remainderof the area an open channel main stem.
The provision of night storage and its location is an importantconsideration in the design of the distribution syrstem below the canaloutlet. A typical 10 ha outlet co:-and is likcly to have about 2 ha invalley-bottom lands. The bottom-lands may either be in irrigated paddyin the dry season, or in non-paddy crops. In the latter case supply ofirrigation will be via unlined channels. These will require a rate of flow
:17 At a rate of 9 litres/sec. Discussed subsequtently

probably in excess of that ich can be supplied by the main stem, butfor short periods, if channel seepage losses are to be minimiszed.A pondage at the foot of the valleY r nlop is therefora desirable.With 20C of the ccaan==d t in ' ottom ' anes in the case ta!. a,some 20/6 of the 24-hourly mply to h ;iutlet comand will be usedin that area. This can concrenicztly be filed at night. It is not,however, a complete answer to the question of night irrigation andnight storage.
Flow in the minors or distributaries in the Kallada system will oecontinuous (24 hourly) during those periods when the canals are inoperation. Flow must be diverted 24-hourly at the outlets to the comnands,or spilled from the canal terminal structure. If diverted it must eithur beused 24-hourly or stored for part of the 24 hours. The pondage at vall7-bottom level in the case taken, could usefully accommodate 20% of the24-hourly supply, or 5 hours. For the remaining 19 hours, includingsome six or seven hours of darlness, irrigation must continue, oradditional night-pondage be provided at some point on the valley slopes.
.The pondage would be of capacity to accommodate six or seven hours of flow,and would be located at a point commanding a sufficient proportion ofthe 8 ha of valley slope to usefully use the ponded water in daylighthours.-
To simplify the discussion, in the limiting case of no valley-bottom lands and 10 ha of valley slopes, irrigation would eithercontinue 24-hourly or a pondage of 12 hourly capacity would be providedat the mid-point of the main stem. The upper half of the command wouldthen be irigated during day-light hours from the main stem, the lowerhalf also being irrigated in daylight hours but provided via the pondagewhich was filled in the prior 12-hours of darkness.
The pondage would be connected by valved lateral into the mainstem, and is an addition which could be made to the system any time.
Whether or not such pondage is provided, the canal outlet and mainstem must operate 24-hourly if spill from minors is to be avoided. Thecapacity at the main stem should therefore be equivalent to the rate ofcontinuous supply at outlets provided in the main canal, i.e. 0.9 litres/sec/ha. Any lesser capacity could represent a constr'iction in the totalsystem. Any greater capacity could only be justified by a diversity factorbetween outlets. As it is desirable to keep capacity at an effectiveminimum wit, pipe systems (less so with open channel) the figure of0.9 litres/sec/ha has been aiopted. It is noted that for this capacityto be adequate the night pondage on the valley slope lnds must beappropriately located, e.g. half way up the main stem in the case quoted,not at the top of the main stem. In the latier location conveyancevia the main stem-a would occur in daylight hours only, and the capacity oPthe main stem would have to be tuice that otherwise required.
Pondages on the valley slopes are not proposed in initialconstruction except on a pilot scale, night irrigation being assumedon the valley lands until agricultural develt,=ent in the projeact Preareachcs a sufc.Jent level to warrant convcrsicn to irr-jio in dzyliguonly. cc ae 4hio; so0=ands where v-lley bct;. lan ara relatively la2ge proportion of the command (sufficient to accommodatethe diversion d:r-ing night hours).

Materials of Construction
The buried main stem will be of high density PVC, with workingpressure rating 2.5 kg/an 2 (equivalent to a head of 25 metres).Moveable laterals could be either PVC or aluminum. Both have been useain India for portable pipe systems. The latter is the most frequentlyused in sprinkler installations. However, for reasons of lower costand less likelihood of theft PVC will be used initially, and is providedfor in cost estimates.
The hose employed (some 65 mm or 4-l" dia) may be of rubber or avariety of plastic formulations. That proposed for initial use, andprovided for in cost estimates, is low-density pimennted polyethylene of 1wall thickness ('Krishi tube", or "lay-flat" pipe). Cost is approximatelyRs. 5 per meter for 65 m. It's life is expected to be at least 3 years.
Cost Estimates
A. 10 ha outlet command, 3% slope, 250 m wide x 400 m lon, withburied pipe main stem and portable PVC lateral (Design capacityof main stem 9 litres/sec).
Description
Main stem: '100 m of 110 mm 2.5 kg/cm 2 PVC (friction gradient0.0083), followed by 150 m of 90 mm 2.5 kg.The total length of hill slope is 320 m, followedby 80 m of valley-bottom land. The main stemterminates 70 m from the lower end of the valleyslope. Total length of main stem 250 m. There arefive outlet hydrants, at approximately 60 m intervals.The lower-nost hydrant is equipped to dischargeeither into laterals or into a mrall stilling basinfrom which flow can continue in unlined openchannel down to the valley-bottom pcndage. The canaloutlet has a trash screen with 110 mm pipe leadingto a valve chamber controlling flow to the mainstem. The pilot systems already constructed alsohave a cistern between intake and valve chamber,intended as a sand trap. As discussed later thismay be deleted in future installations. Forthe present, however, nominal provision has beenmade in estimates for such a structure.
Hydrants: Five, each of 90 mm diamie'er with 90 mm Tee, and90 by 75 mm reducers and valves serving the left andright branches of the portable lateral.
Laterals: The alternative assuned for estimating purposes dividsthe 9 litres/sec flc,: in the min. sten, between leftand right laterals, each ta ing 4.5 litres/sec. Thespigots are of 2.25 litrej/sec capacity, with twooperating at a time on eaech side. One set of left andright laterals is prvide.+ 75 m 0D 4 kg FVC pipelength each side approximately 64 m (14 lengths of6 m). -/

Connection of 6 m lengths by simple spigcot and socket,held by screw clamp if found necessary. Each sideprovided with two valved outlet pieces, comprisinga 75 mm Tee and 75 to 63 mm reducer, with 63 mm valveand short 63 mm spigot for connection of hose. The valvedoutlet pieces may be located wherever required in thelateral, by disconnecting neighboring lengths of thelateral and reconnecting with the outlet piece inserted.The end of the outer-most length of the lateral is closedith a threaded coupler and removable metal cap.
Hose: The 65 mm hose has a short length (20 cm) of 63 mm PVCpipe permanently attached at one end, by which the hosemay be coupled to a 63 mm valved outlet.by spigot andsocket joint, and screwed clamp if needed. The hoseshould be about 100 m in length, divided into sectionsof 25 F by three spigot and socket joints on shortsections of 63 mm PVC pipe pezmanently attached to thehose. Repairs to the hose may be effected by cuttingand inserting short sections of PVC pipe similarly,.A set of two hoses for each side of the lateral shouldbe provided initially, with cultivators purchasingreplacements or additional hoses.

Comments on above estimate:
Not included is the cost of a pondage at valley-bottom level,where required (this item is covered elsewhere in project estimates),nor unlined open channels in the valley bottom lands. Also not include.is the provision for an open-channel lateral at the upper end of theoutlet command. This may be required in some circumstances whereinsufficient head is available at the upper end of the command fordelivery of full flow via pipe lateral. An alternative to an open channelin this circumstance is to supply by pipe lateral at -reduced flow forlonger period by an exchange arrangement with the next lower lateral.
Two items call for further design study. These are the sandtrap and the hydrant chambers. The sand trap could probably be eliminated,as sand deposition is not likely to be a problem with the velocitiesprevailing in the pipe system (up to 1 m/sec in the main stem)., Thehydrant chambers appear disproportionately costly (equivalent to 45%of main stem pipe cost). An alternative design of-hydrant using a 3,|-"galvanized iron riser pipe with flanged couplirg at the lower level,is likely to prove sufficiently robust without recourse to a surroundingchamber. .Present estimates, however, have included sand trap andhydrant chambers.
B. 5 Ha outlet comand, 35 slope, 200 m x 250 m long with buried pipemain stem and Dortable PVC lateral (Design capatcity of main stem4.5 litres/ec).
The area of an outlet command is partly determined by toDographicfactors and may be as low as 5 ha. As the cost of distribution systemper ha is likely to be higher with smaller outlet comiand, estimates arealso presented for a 5 ha area.

A 10 ha area on lf% slope could be served by a 110 mm pipe (gradient

The difference in cost of the completed system would be approximately160 x 9.15, rounded to Rs. 1500, giving a total direct cost of Rs. 31,500compared with Rs. 30,000 for 3% slope.

place of the hydrant chanber is likely to reduce this cost, probabl;-to the vicinity of Rs. 5000, or Rs. 500 per ha. The correspondin,structures for the lined open char7el system wovld include 5 gatedturnouts, probably 5 drop stractures (oivher than simple chutes fo=m(i

of Rs. 3000 to Rs. 5000, depending upon the topography of theparticular site.
It is concluded that within the accuracy of present generalizedestimates the costs of pipe and of lined open channel systems for
slopes down to 111 are vezr similar. For appraisal purpoces cost
may be taken as for the lined system throughout. In actual projectimplementation choice between pipe and linied channel, for slopes less

OFFICE MEMORANDUM.TO: Mr. Wilfried P. Thalwitz, Director, ASPDR DATE: March 16, Y-7.
FROM F.H. Lamson-Scribner' Chief, ASPEW
SUBJECT: INDIA - Upper Ganga Canal (UGC) Irrigation ModernizationUttar Pradesh (UP) Project Preparation
This is an answer to your question on the desirability ofplanning for an exclusive power transmission grid for equipment which mightbe included in the UGC irrigation modernization program. As we discussedon the telephone, I've discussed the proposed project with W.G. Rodger andoffer the following comments.
As I understand, a part of the project is-to provide largedeep wells with electric pumps which would pump from deep aquifers andsupplement the water available from the Ganga by providing more water intothe canal system. Basically the big pumps would pump into the overallirrigation canal system. Although final plans must await further study,Rodger indicated that there might be as many as a thousand pumps spreadover a large area and that such pumps might have general capacities in the400 cubic meter per hour range (total electrical load might be of the orderof 50 megawatts). Rodger also indicated that for the supplementationscheme to work, the pumps would have to be provided with as reliable asource of power as possible and he would expect that the pumps would haveto be operated in the order of 8-10 hours per day. He also consideredthat the present electricity distribution system did not have adequatereliability and that it would not be worthwhile to put a large investmentof electricity consuming equipment in an area where power supply was notreliable enough to guarantee the efficient use of such equipment. Theseare valid observations and conclusions.
The objective of the augmentation program is to provide waterto the canal system. We are then concerned with the total system to providethat water which if done with electrical pumps includes the power generatingfacilities, high tension transmission lines and substations to provide powerover the large area involved, low tension 33 and 11 kv distribution linesfor smaller geographic areas, and finally the electrical facilities andmotors at the pumps. Since the area involved where the new pumps would belocated also corresponds to areas where there are existing or planned ruralelectrification systems for other pumps, small industry, and villages, it isalso desirable to consider the total electrical system. It would probablybe anti-economic to have two wires down the road, one for the existing orplanned normal rural electrification system and another for the UGC augmen-tation pumps.
Overall reliability is the key concern of the electricalsystem if the new pumps are to be justified, although it should be recog-nized that there are tradeoffs between reliability, system costs, and consumerlosses due to power interruptions. In genErai, the overall reliabilityof a system basically starts with the generacors and goes through the high-
Mr. Wilfried P. Thalwitz - 2 - Wirch 16, 1981
tension transmission to the lower tension distributio. If, as is proposethe electrical demand for the augmentation wells is to be satisfied by thegenerating stations and high tension grid of the UP State Electricity Boatr.(UPSEB), then the reliability of the UPSEB generators and grid is rele ant,regardless of whether there is a separate distribution grid for the augmer-tation well motors or not. (An alternative might also be conceived thatthe augmentation well electrical demafids would be provided'for by a separa,:generating system but this would indeed be anti-economic since it would putthe electrical system for the pumps in total in parallel with the UPSEB;one would have to have generating stations, transmission lines, and distri-bution lines as a parallel system in order to be isolated completely.) Itmay therefore be necessary to improve the reliability of the UPSEB's genera-ting/transmission system or to consider that reliability when consideringoperation of pumps.
As regards the final distribution system at the 33 and 11 kvlevel, the reliability of this portion of the system is dependent on itsdesign and operation, on acts of God (lightning and lorries striking poles)and on general overall maintenance. A separate system for the augmentationwells would have the same risk factors to consider reliability-wise as thepresent system.
We might also wish to consider whether or not it would beeasier or more efficient operations-wise if the electrical system werebuilt or operated by the UPSEB or perhaps by another authority. Ingeneral, the same problems must be faced regardless of who builds oroperates the system. Further, although certainly the UPSEB might not bea model of efficiency, it is highly questionable whether a new authorityor one without experience in construction and operation of power distribu-tion facilities would be more effic*ent and in fact it might also be prognosedthat there would be a learning curve for such new authority (or new respon-sibility for an existing authority) and more difficulties might be encounteredthan at present. Further, since a fair amount of the operation depends onmaintenance, it would be anti-economic to have two sets of operators andmaintenance crews spread around the state, the one to maintain the UGCaugmentation system and the other to maintain the UPSEB system.
Perhaps we should consider the alternative of working withand improving the present power system in the UP in the augmentation wellarea, to provide not only economically relialle power for the UGC augmen-tation pumps but also to provide adequate power for all the other consumersin the areas affected. To this end it would be desirable to review thepresent and planned RE system in the general UGC augmentation area, tointegrate this with the expected demand for UGC augmentation, and to developan overall system which would provide for all consumers in an integratedway. Basically, che UPSEB should be informed on the potential power demandfor augmentation (50 Mw is a good sized lump), and the UGC authority and theUPSEB should work together in overall system design. Based on this, aproject or subproject for electrification would. be developed. To construct
Mr. Wilfried P. Thalwitz - 3 - March 16, 1981
an overall satisfactory systc= wculd probably be no more difficult and
might be less difficult than to construct a separate parallel system, and
overall it would be more cost effective.
Harking back to my memorandum of March 11 to Roger Rowe, this
project provides an ideal cpportunity to integrate the interests of an
agricultural power consumer and the power supplier. First, the overall
distribution system should be developed reasonably optimally. Further,
in developing the distribution system and its voltage levels, a balance
will need to be struck between line lengths, voltage reductions in trans-
formers and sub-voltage levels if any, and motor characteristics. Next,
certainly the motors should have power factor correction. Lastly, this
project would offer an ideal opportunity to introduce time of day use and
arrangements should be made for the agricultural pumping to be done during
those periods of the day when power demand on the total UPSEB system is at
its lowest, say from 10 p.m. to 6 a.m. This is especially important in
India's Northern Region where there is a projected 10-15% shortfall in
generating capacity (during peak periods) as compared with presentlyenvisaged demand (probably excluding this project) throughout the 1980's.
ASPEW will be happy to work with ASPAC in this whole regard.
Other institutional matters may arise such as how funds should be channeled
to UPSEB for the power component of the project, but I am sure this will not
represent a stumbling block.

Construction is being actively pursued but award of thecontract for PVC pipe, a principal item, was still held up at StateSecretariat level at the time of mission departure (December 12),in spite of best efforts by Bank to secure its release. Sufficient pipefor only 20 tubewell distribution systems was available at 12/12, andmost of this had already been installed. Sanctioning of the two 0 and MDivisions provided for in the project, permitting posting of JuniorEngineers and Agricultural Supervisors to supervise and monitorperformance of wells, is also delayed, and there is believed to be someunwillingness at Finance level to implement the provisions of the loanagreement regarding numerical strength of Agricultural Supervisors.The problem may stem from the complete change of personnel atSecretariat and Ministerial level since project appraisal and loannegotiation. The project is strongly supported by GOUP, and both Stateand Central Governments are urging processing of the much larger secondstage project in time to pezmit orderly transition from first stage.However, GOUP Secretariat does not appear to appreciate that tardinessin implementing the provisions of the first stage project couldjeopardize timely appraisal of the second. Central Government (DEL)is exerting pressure on GOUP, but if delays continue a joint GOI, Bank,GOUP (Ministerial level) review of the progress on the first stageand prospects for the second stage may be desirable in early February.
With regard to data base for the second stage project, theprogramme for the baseline and post-project (1983) evaluation studiesof the first stage provided for in the appraisal report was reviewedwith the contractor, UP Development Systems Corporation; also theadditional short-tez evaluation studies necessary for early appraisalof the second stage project. The UPDESCO baseline studies focus onseven selected typical districts in each of which three -of the fortyproposed project well sites are randomly selected (one of each of thethree well capacities). In each of the three well sites 30 farmers areselected (covering a range of holding sizes)for detailed reporting.In each of the seven districts an existing well of the earlier type isalso selected for similar analysis. In the selected fazms demographicand production data are studied in detail.
In the present circumstances of the delayed start on the firststage project, and the earlier initiation of the second stage nowbeing urged by Central and State Governments, the benchline and post-project first stage evaluation studies will be of less relevance tosecond stage appraisal than originally intended.
Appraisal, if carried out in March '82 as is tentativelyproposed, will necessarily be based on limited data (six wells) fromthe 1980/81 rabi season and more substantial sampling from hot-weather(said) and kharif '81, also rabi 181/82. Apart from the initial six,the wells selected for 1981 season production and yield surveys willbe nine of the 21 (7 distriats x 3 wells) randomly selected base-linesurvey wells. Analysis of 1981 production data on these and the
-3-
initial six wells will be carried out as a joint operation betweenDepartment of Agriculture (crop cutting) and UPDECO through anextension to their contract.
While the first stage project will provide ample data oncosts and technical performance of wells in time for appraisal of thesecond stage, production and yield data will generally be from thefirst irrigation season only. Comparison with areas under longestablished traditional wells, or with rainfed production, willtherefore be of limited value unless tempered by a good deal ofjudgement.
One purpose of the mission was an assessment of the extentto which cultivators taking up irrigation under six project wells forthe current '80/81 rabi season had been assisted or prepared for itby extension. In fact they had received virtually no assistance, theAgricultural Supervisors not having been posted, and they wereunderstandably following traditional practices in a wait-and-see frameof mind. I/ This underlines the urgent need for activatingextension prior to the '81 (said) season, as the proposed hot-weatherirrigated mung crop ill be quite unfamiliar to cultivators.
The subject was discussed with the Director of Agricultureand the (new) Agricultural Production Commissioner who volunteeredimmediate posting of five Agricultural Supervisors. However, continuedpressure and surveillanoe of the situation is necessary. A furtherfield visit by CP agronomist in March is proposed.
Naharashtra I Project, Aurangabad
The purpose of the visit (27/11 through 29/11) was to reviewthe proposal from Rosacometta (Milan) for supply to the State of twelvemachines for production of concrete water course lining components.Component design was also finalized (a drawing of the design adoptedwill be forwarded to Bank under separate cover). The priced proposalsand designs were also reviewed with Secretary Irrigation in Bombay.A visit was paid to a Bombay firm which is producing a replica of theItalian machine on a trial basis (the firm has contacted Rosaomettaregarding possible technical collaboration).
Copies of mission letters to Y. Pret, Bank 1DO, of December 8(including a suggested draft letter Bank to State confirming Bankconcurrence in direct procurement of the twelve machines) are attachedto Management and Bank copies of this BTO.
An issue stressed with the State is that production capacityof the lining components now far exceeds current rate of installation.Watercourse construction and lining need to be accelerated in theproject as a whole, as well as in the pilot area. It is suggested that

the programme be reviewed by the proposed Bank mission in late January.
Kallada Project, Kerala
Kallada project is now at the stage of report writing by a Bankappraisal mission. It was prepared jointly by the State and theCentral Goverment Project Prepararion and Monitoring Cell. Annualrainfall is 2,570 mm, virtually all occurring in the six-month monsoonseason mid-Jiay to mid-November. Soils are lateritic (ferrisols), butwith good management are reasonably fertile and free draining. Irrigatedupland crops will include coconut, plantain, rubber, cassava andvegetables. Lowland crops will be paddy in the monsoon season followedby vegetables and oil seeds in the dry season. Irrigation of rubber, anunusual feature of the project, is reputed to give high returns at presentprice levels.
Irrigation of the garden lands, generally on slopes of 2% to5% or more, is complicated by the fact that the area is already largelyunder mature coconuts, planted without regard to future application ofirrigation. There is very limited possibility for land shaping.The terrain is irregular, the area is highly developed, with dwellingsusually within each holding (av. 0.2 ha), and land values are vezyhigh ($13,000 per ha). Short of irrigation by sprinkler the onlypractical means of water delivery in the circumstances is by pipe, withfield application by hose or flexible tube, often to individual palms.
The mission was asked by Bank to assist the State in designand layout of suitable ystems, with costs within the levels assumedin appraisal (some $400/ha for works within the 10 ha outlet oommand).A combination of buried PVC pipe, moveable quick-coupling laterals, andhose or lay-flat tube was developed for the purpose. The system, andthe altenatives considered, are described in the mission memo ofDecember 6 to N.C. Vikraman Nair, Chief Engineer, copies attached toManagement and Bank copies of this report.
A remaining issue is the treatment of areas with slopes lessthan 3% (originally conceived as the lower limit for pipe systems).It is likely that pipe systems will be found desirable on slopes flatterthan 3%, particularly in view of land costs and right-of-wWy problems.The question will be further pursued in the next mission.
The Irrigation Department was asked to prepare contour surveysof typical areas (some 500 ha in total) on which typical systems willbe developed with Departmental engineers during a further visit inFebruary. The designs will be used in staff training, for which Bankhas also requested CP assistance.
Damanganga Project (Gujarat II)
Damemganga is the southern-most unit of the Oajarat II (composite)project, for which an IDA credit was negotiated in mid-80. Rainfall is1,800 mm. A feature of the project proposals is conversion of some40% of the area currently under rainfed grass (cut for hay and soldin Bombay for fodder) partly to irrigated orchard crops (20% of the
e-5-
project area). These are expected to include irrigated mango, chikoo,plaintain, sugar cane, vegetables, and coconuts. The appraisalreport envisages that 30 to 40% of the Damanganga command will be servedby pipe distribution system ( below the outlets from the minor canal),where slopes permit.
It is noted that the situation at famanganga differs fromthat at Kallada, in that the former command is largely undevelopedand land shaping for irrigation in advance of planting of orchards ispossible. In contrast mature orchards already exist at Kallada.Farther, as newly planted crops such as mangoes and coconuts requiremany years to reach maturity the returns per hectare in early years fromthe Damanganga area are likely to be much less than from Kallada, andwill justify less expenditure on the delivery system. The task isto design a system suited to the requirements of mature garden lands,but which can be constructed or extended progressively, with modestinitial outlay.
The mission found some reluctance on the part of the IrrigationDepartment 'to accept that Government should be involved in any waywith water distribution below the outlet from the minor. Designs whichhad been prepared on a pilot basis for pipe systems were in fact pipeminors. The same philosophy was reflected in the opinion that "nothingbeyond the one-metre interval stereo-photo contours was necessaryfor planning of land development". This misapprehension was largelycorrected during the course of the mission (probably reinforced bythe subsequent visit of G. Finlinson, Bank). The impression remains,however, that design proposals for the intra-ohak distribution systemfor will be scrutinized very critically at Secretariat level,and should be well substantiated. 1/
A mission memo of December 10 to Chief Engineer L.W. Vakharia(c.c. Bank NDO) discussing the application of pipe distribution systemsto Damangaga is attached to Management and Bank copies of this BTO.A survey of a minor command (scale 1:2,000, 20 cm contours) preparedfor determination of percentage of various slopes is available, and itwas agreed that the Department would proceed with designs for completefarm delivery systems , in this area, to be used during the nextCP visit (February) for analysis of watercourse systems (pipe and openchannel as appropriate). Conclusions from this study will be reviewedwith Bank prior to proceeding further).
J/ There is some ambiguity in the Appraisal Report which refers tolining "down to the 20 ha level" in D " on page 22 of Vol. I, and"lining would extend down to 8 ha blocks" with refereoce to onpage 5 (para 3.02 c) of Vol. III.

Dear Yves,
Re: Maharashtra I (Jayakwadi) ProjectNovember 27-29, 1980
The main purpose of the visit was to review withVarudkar, and subsequently with Saldanha, the proposal receivedfrom Rosacometta for the supply of twelve extrusion machinesfor manufacture of concrete c mponents for lining of water-courses (a copy is on your file). Discussion centred mainlyon comparison of costs quoted by Rosacometta for the V6Tripla with those quoted for a local replica of the same machineby Sureseal of Bombay. Sureseal is supplying one copy of theV6 and has quoted for six. Based on the latter quantitythe Sureseal price is some 15% higher than Rosacometta (deliveredto Bombay) if excise and duty is disregarded in both cases.If 15% preference is given to the local supplier, the twoproposals are vittually equal.
A comparison of current prices proposed by Rosacomettafor V6 and V5 machines with earlier quotations for FAO- pro-cured visits, indicates sthat prices have increased more thanthe official Italian inflation index for industrial machines.The net increase is difficult to determine, however, as Rosaco-metta prices are adjusted at infrequent intervals. For theV6 the net increase (above inflation index) could be between10 and 20%. For the V5, nil to 10%.
The Sureseal offer virtually amounts to a competitivetender, and indicates that the Rosacometta current prices arewithin reason. As the State does not wish to go beyond oneSureseal machine until that unit has been in operation for severamonths, Varudkar, also Saldanha and C.E. Projects Gupta, proposeto proceed with procurement of twelve machines (six V6 and sixV5) from Rosacometta.
Possible alternative designs for components were alsoreviewed with Varudkar (three alternative C.P. designs hadearlier been discussed with Rosacometta), and one selected as thebases for mould design for the V6 machines. The mould for theV5 will be similar to that supplied earlier through the FAO TCPproject. Varudkar agreed to C.P. finalizing design details forthe component to be produced on the V6 with Rosacometta, onbehalf of the State.
-2-
The V6 machine being constructed by Sureseal (andalmost completed) was inspected on 30/11 in Bombay. It is an
exact copy of the Rosacometta V6, except for substitution ofwelded fabrication for certain castings. Workmanship looked
very good, also the capability and qualifications of the firm's
management. Their regular business is the manufacture of
hydraulic control devices for municipal water delivery systems.
Sureseal has approached Rosacometta regarding possible future
technical collaboration. -
Varudkar would appreciate a copy of earlier Bank's
letter or telex supporting direct procurement of the twelve machinm
from Rosacometta (or re-confirmation if that is more convenient).I concur in such procurement on this occasion.
The V6 machine is still in Paithan, and operating
steadily. However, Andhra Pradesh have sent an officer fortraining in its use, and is expected to take delivery of themachine within the next two weeks. Further trials on mixdesign were run during the visit, including volumetric
proportions 1 cement, 3 Godavari river sand, 3 crusher fines,3 crushed aggregate (to 10 mm). This gave a very superior
surface and probably much better impermeability than the currentlyused mixes. Strength and permeability tests will be carried
out. The crusher fines (referred to as "rock dust") have more
than 50% above 1 mm size and blend well with Godavari river
sand. The crushed aggregate has 60% less than 4.75 mm. The
1:3:3:3 mix is, in fact, a well-graded blend, although at first
sight rather untonventional.
A minor electrical problem, probably in the thermal
overload relay has put the V5 out of action temporarily.During the visit a meeting was held with the Maharashtra State
Electricity Board with regard to supply voltage at Paithan ane-
Maharashtra II projects. (MSEB maintains this voltage is held -
at within 6% of the nominal 440 volts).- The Board alsorecommended an experienced industrial electrical fiu
(Sattaya Electricals, Aurangabad) for servicing the V5 and V6
machines.
- The stock-pile of trapezoidal channel lining components
is now very large, and increasing daily. - Production is far
exceeding installation. This was discussed with Varudkar ,with the new Executive Engineer Pilot Project G.N. Deshmukh and
later with Saldanha. It is evident that a campaign for
watercourse construction, both within the pilot area and
throughout the project needs to be set in motion.
I expect to be in Aurangabad again about mid-February.
Yours sincerely,

Dear Yves,
Re: Procurement of extrusion machines fororoduction of channel-lining components
Further to my letter written earlier today, I enclosefile copies of letters Saldanha to O'Brien (11/2/80) andO'Brien to Saldanha (18/2/80), also Fenn (C.P) to Saldanha(11/3/80) on the above subject.
As the tender since received from Sureseal (Bombay)indicates that the Rosacometta's offer is within reasonableprice range, it may be simplest to reconfirm, to Varudkar,that Bank is in accord with direct procurement, along the linesof the suggested draft (you may wish to copy by telex toWashington before forwarding).
S.L. Varudkar, C.A.D. Administrator, Jayakwadi Project.
Reference letter O'Brien to Saldanha pf February 18, we'understand that a firm offer has now been received fromRosacometta for the supply of six V6 and six V5 machines, andthat Sureseal (Bombay have also made a proposal for six V6machines. The price per V6 machine including mould obtainedby Rosacometta is equivalent to Rs. 152,000 landed at Bombay,and the Sureseal price per machine including mould based on anorder of six machines is understood to be Rs. 176,000, bothprices without excise or duty. The Sureseal offer isapproximately equal to the Rosacometta price plus 15%. Weunderstand that you wish to limit supply from Sureseal to the onemachine now being constructed pending field trials, and toproceed with direct procurement of six V6 and six V5 machines andassociated equipment from Rosacometta. -Subject to youdividing the orders for each of the 'projects', if necessary,to stay within the Project Agreement, as advised in Mr. O'Brien'sletter, the Bank is in accord with your proposed action.

The follo-ing notes on system desig. amplify discussions during
mr three--day. field visitI and. in meetings with project staff.
It is acknowledged at the outset that the use of buried pipe
for on-faxa vater distribution in a canal cc= is a new departure
in Inai-m irrigtion practice. It is amply juztified in the circumstances
of I I with intewive cultivation of gard crops in steeply sloping
topogr-pby. Howver, technolog has to be tested, and some modification
mid dezigns =xq be acpeoted as the wvok procedes ad as eperience gc i-cd
is gained - particularly conoein cultivator reactions. In these
circstles initial installations zhould provide sufficient flexibility
to aocorsodate wV developments in design, materials applications, or
oporation. which may be suggested by early experience with the system.
In the follc,4.ng notes the rnge of technical possibilities is discussod,
=d a dIe . approach upon which initial layout and construction could
prceea is ZUggestcd. This is similar in many respects to that proposed
by De=-Im=otal staff, but with some Iurther consideration of the field
delivey end of the systam.
Water D-eand at the Field
The ma-4m= water demand for the Zallada Eustem as a whole occurs
in xaxzch. The wmaot of paddy proposed in hot weather is small, and
cultivation of vegetables and other "irrigated dry" crops in vallW-bott
lands mill be Encouragez&in this seasont where soil conditions permit.
For present purposes it is ascmed that the whole area serred by an
outlet will be under garden crops in the critical month, with water demand
at the field 0.73 litres/secnd/ha if applied continucusly (see page 11 of
Jt'-y 80 Project Report).
Hours of Irzgation, and Capacity of ain Stem of Pine System
Drnng iharif and Rabi seasons when valley-bottm lands are
in paddy the et-lwA portion of a catlet cand will probably be
irrigated at night and the .aden lands dmrin dalight hours. In uarch,
however, the whole of the outlet occiaand is aesumed to be under garden
or vegatable crops. Fawtors infliiencing the question of day/night
irrigation include the following.

The gardan land are divided into vezy small plots,typically an individual basin for each coccnxt palm.Close attention and frequent manipulation of theirrigation stream will be necessary, Plots maW belar.-er in the valley-bottom landz, but will neverthelessbe =ch =aller th=n cut.mazy for field crops. In thesecirc.-tnces iriigsation during dalight is likely to beCons 4z bly more efficiont than daring night hoursUnless vozy effective lighting is uned.
Howcver, holdinrs are small (zverage 0.2 ha) and usuallyadjacet to the cultivator's dwelling. Some of the usualobjoctions to night irrigation (security, etc) consequentlydo not apply in this area.
Migbt pondaee is un:er considration, either at the levelof the bottom lmdrs if stfficient area in commded thereby,o= at n intemediate level on the sloping Sarden lands.Part or all of the night flow from the supply canal will betored in such circustanes.
For present purxposes it is assed that irrigation uill be carried outfor sixte hoIrm per daW (as practised olsewhere in the State on punp-liftprojects) in the critical hot-weather months. Supply from the canal will bestored for the x'c.&ining eight hours.
The affect of the assumpticn regareing hours of operation, on rateof flow in the pipe &rVt= sarving the outlet crand is as follows.
(a) If 24-hourly irrigatian were iratised the rate of flow imithemain stam of the pipe syste= the central dotm-slope pipe) wouldbe 0.73 litres/soc/per hoctare of outlet coWMmd (this is therefernce case).

Rate of dleliveg= (stream size) at Indivianal Plot
Taking case (c) on the basis of design and assming for the mamentan outlet crrmd of 10 ha, the capacity of the main stem would be 11 litres/aw. This could be delivared to the fiell in a =mber of ways, either asa sinale stre= of 11 litjres/sec. or as two atreams of 5.5 litres/sec oras fcar of 2.75 litres/sec. In relatively flat topography, and viere landhas been shaped into terraces or basins of appreciable sise to receivejrjisaticn, cultivators would usually prefer the single stream of 11 litres/sec.In the 1afl n czni , however, mature palms are groAlng on sloping landsof irrealar topography, generally vith suall basins formed around each palm,and the possibility of re-shaping of land to facilitate distribution ofirri.-tion water is rather Limited. In most cases water will have to beconveyed to the individual palm, or =iall plot of other crops, by pipe andfleible hose. The alternative of sprinkler distribution is ruled out, forthe present, qn groz's of cost =d energy requirement.
A etream of 2 to 3 litres/sec. appears to be the desirable sizefor delivezy to the individual palm (the area of basin around the palm isabout 5 sq. mctres in extent, situated in a bounded area of sce 30 to 40 sf.metres per palm). The time of watering into thi inner basin at 2.75 litre;/see, with irrigation once weekly, would be 14 mimntes.
A cultivator t4th 0.2 ha (the averegze size) would probablyfind it ccnvanient to use two Such streams, moving one hose at a. time, taldna total of 5.5 litres/eeccnd. Two cultivators (one each side of the mainstem) would thus take the -hole flow of 11 litres/second. The time taken toir.i.Late the 0.2 ha holding (nce veekly) usine 5.5 litres/sec. would be about4.5 hours.
The above flows are for an outlet cr=an. of 10 ha, with supply 16 h.-per daV- For a. &aaller outletcqmiFnad jnd the same supply period of 16 Irflows would be proportionaLly reduced. -
Shane an& Size of Outlet Coanma
A factor detezined by the topograpby of the project area is thelength of the outlet menA. This extends from the contour canal ordistributazy domx through the sloping garden lands and across the valleybottom, or part-way across if there -is a similar canal =d outlet o==dto var7 from a (arceptional) minlim of as 60 = to a ma"i" of 500 n, butis most ccnonly in thn range of 200 to 400 m. The width of the outlet
- - ccamd is to a=e artent optionalr within limits imposed by topography andm-rie desirable size and width imposed by design comaiderations.
The nouinal ms.mdm -size of 10 ha has been determined partly with regardto kee=ng the nuber of cultivators ser7ed by an outlet within limits, tofacilitate their organization for water sharine. In fact the size willfrequently be less than 10 har dne to topographio limitations on length anddesian limits an width.
The width of the outlet Comamd is an important design consideration.
ith the exception of comands of very short length (100 to 150 m) which
are discussed later, the basic system is square or rectangular with longerdimension doun the slope. A single buried pipe, the "main-stam" runs downthe centre of the cccmand and is provided with hydrants at intervals of soe
50-60 m. The design problem is distribution laterally, from the hydrantsto the outer limits of the cemand. Distribution doD-slope is relatively
- simple, as advantage is taken of the natural gradient. Distribution laterallyis across the slope (or diagonally), without the assistance of topographic
gradient. For this reason an upper limit of 250 m has been placed on width of
outlet coand, i.e. 125 m either side of the main stem. This limit should
be reviewed on the basis of early experience. A lesser width would. make for
greater facility in lateral distribution, but at increased cost.
Carez&s of very short length will necessarily be served by ahorizontal "main stem" of either pipe or open canal at the upper end of theccand, and secondary (moveable) pipe or hose domn,-elope. In this situationthe only constraint on width will be imposed by topography or the upperlimit of 10 ha area.
The Lateral Distributicai System-
Distribution from the do-,=-slope main stem to plots up to 125 z inlateral distance from it could be effected by several alternative meansincluding.
(a) Baried rigid pipe branches or laterals at intervals doun theslope, each having outlets along its length serving cultivatorhoses.
(b) Small lined ccntcu-r channels at intervals, serving cultivatoroutlets.
(a) Portable pipe laterals, connected to each mai-stem hydrantin turn. The laterals have outlets along their length toserve cultivator hoses.
(d) Portable flexible hose serving both for lateral distribution andS.spply to individual plot.
The syster (a) with buried pipe laterals would be the most convenientoperationally but would be undesirably costly. Such fixed laterals could beadded at any time, when justified by degree of agricultural development.

In system (d), usi.ng ctirely flexible pipe for lateral distribution,
a principal questi=n is the type of pipe or hose to be used. As sho'n on
Table 1 the head loss for 50 = PVC hose for a flow of 2.75 litres/sec. (one
quarter of mai..siem flow) would be 4*5 m per 100 m or 5.6 m for the 125 m

7-Cost Estimates
Costs for a 10 ha system (250 m wide x 400 m long with 3Zslope)above were prepared on 6th December by Departmental staff. With minor
modification (provision of two moveable laterals rather than four) theseestimates are -set out in Table 2. ' Cost per hectare for the 10 ha systemis Rs. 2,940. The figure is without engineering and administration, or\contingencies.
Costs for a 5 ha system (200 m wide x 250 m long with 3% slope)have been estimated on the same basis, using smaller diameter pipe andshorter lengths as appropriate to the smaller command. Equivalent costper hectare is Rs. 3,360.
Materials and Technology Employed
The "main stem" buried PVC pipe and hydrants are as previously- proposed, and call for no comment. The 90 mm diam. moveable laterals,
each 75 a in length (70 mm diam. and 50 m length in the 5 ha case)are an important feature of the design, providing points for connection ofshort (60 m) individual hoses or flexible pipe. The laterals may be of2.5 kg rigid PVC pipe, or light-weight aluminium pipe as used in
-a-moveable sprinkler irrigation sets. In either case the pipe is in 5 mor 6 m lengths (easily carried), the lengths being connected by quick-atting snap couplings. These are readily available for aluminium
irrigation pipe, but would probably have to be designed for PVC pipe.Alternatively short lengths of aluminium pipe could be cemented into theends of the PVC pipe and conventional aluminium pipe couplings used.Each lateral would have a valved outlet (for hose connection) at threepoints along its length (two points for 5 ha). These do not present any
problem for either PVC or aluminium.
A third alternative for the moveable laterals, for future considEtion, is lay-flat Polyurethane (Krishi pipe), fitted with valved outleL-However, although this material in substantial thickness (0.7 mm) isproposed as alternative for the 60 or 70 mM flexible hoses, the otheralternatives being rubber or flexible spirally reinforced PVC, there isinsufficient field experience with lay-flat pipe in India to justify
basing project estimates on- its use for the 90 mm laterals. It is,however, very much lower in cost than rigid PVC or- aluminium (some Rs. 5/-per metre for 0.7 mm thick 90 mm diameter) and it should be tried outf 6cr
laterals early in project development. Such pipe could, of course, beused to convey water directly from the hydrant on the main stem to the
individual field, without recourse to moveable lateral and branchinghoses. This is not recommended, however, for two reasons. Firstly theflow of 5.5 litres/sec from the hydrant (each side) in the 10 ha case istoo great for -supply to one plot, and secondly, continual movement of a90 mm line, 125 m in length, dragging it from'plot to plot, would be un-desirable. As a moveable lateral it would be moved once daily only, whileempty.
Distribution systems for slopes of less than 3%
This subject was discussed briefly only, during the visit. The
lined open channel system proposed is a conventional one, but in the
particular circumstances of Kallada it poses two problems,/ Firstly, if
the command is as intensively cultivated with mature garden crops in the
area with slopes less than 3%, as in the steeper area, the technical
problem of water distribution from a canal system within the holding may
be a difficult one. Land shaping for water distribution by unlined farm
channel is a possibility in areas of perennial crops (e.g. bananas), but
scarcely in mature coconut plantations planted.without regard to geometric
pattern. -Secondly with land values of Rs. 50,000 to Rs. 100,000 per
hectare a lined open channel system with 115 m of channel per hectare of
garden lands is likely to incur a financial cost of some Rs. 10 per metre
of lined channel, as well as considerable cultivator resistance to R.O.W.
acquisition (this is being encountered in Kallada even with buried pipe).
It is concluded that extension of the pipe delivery system to slopes
of less than 3% may prove desirable. (A 110 mm pipe can serve a 10 ha
area with slopes down to 1.5%). It.may therefore be desirable to leave
the questiin of pipe or open channel system flexible in defining the
project for purposes of appraisal. This will be discussed with Bank in
New Delhi on 12th December.
Action prior to next visit
As discussed, in addition to your present survey programaor as part
of it, it would be desirable to prepare 30 cm contour gurveys of ftur or
five areas each of about 100 ha, representing typical topographic situations
prior to next visit (second half of February). Surveys of these areas would
be useful as staff training classroom material.We also discussed having a
reconnaissance carried out over the project command as a whole, to assess
the proportion of outlet commands which could utilize an existing tank or
pondage at valley-floor level, for night storage. Cost of constructing a
lined pondage of 300 cubic metres capacity appears to belof the order of
Rs. 9000 to Rs. 10,000 including R.O.W.whether excavated and lined, or
circular above ground constructed from pre-cast tiles, with hoop reinforce-
ment. This would be sufficient capacity for 8 hours of night storage for
a 10 ha outlet command. The estimate is an approximate interim figure;
costs should be worked out in more detail by your staff.
Many thanks for an interesting and enjoyable visit, I look forward
to visiting your area again early in the New Year.

Apnlicaticn of pipeline to _Danan a Project
The following notes record our discussions following a visit
to the project area, and review of documents prepared by your staff.
Pirstly, to clarify a question of scope, pipeline may be used
in Damenganga both in the distributary and minor canal system, and
below the outlet from the minor or sub-minor, within the outlet comand,
Utilization in distributaries or minors has a parallel in a local
area in the Umi-Jarapar command where, in the special circumstances
of flood inanation, buried pipe was used instead of open canals.
While imuation is not a likely hazard in the -eanganga project,them are situations in which it may nevertheless be technicallydesirable to use buried pipe in portions of a distributary or minor.
Use of pipeline below the outlet from the minor or sub-minor,for distribution within the outlet coim-nd, is a different type of
application and for a different purpose. It is referred to in the
Apprmial Report Vol,. I para 3.05 "The distribution system (from the
minors doi) would, be in pipes wherever sufficient natural head is
l . . Also in Vol. II pare 3.05 "In pipe srstems
tunouts will be pravidzd to blocks of 3 to 4 ha., depending upon
topograpby of the land". This second type of application is the subject
of the present discussion. It is acknowledged, however, that there
is possibility of misunderstanding as to whether the turnouts serving-
blocks of 3 to 4 ha, referred to in Vol. II, were intended to be
direct turnouts from a piped minor, or turnouts in a piped water-ocurse
extending below an outlet from a minor (piped or otherwise). This will
be cleared up shortly with Bank*
For the remainder of this discussion the pipe in question
is taken to be an alternative to a lined watercourse, in distribution
of water within the outlet c-nmand, or ohak, either to sub-chaks or
more generally. The situation in which distribution by pipeline is
afvantageous are discussed, and also the possibilities- for a minimum cost
initial system capable of being developed further as agricultural
development within the outlet command is intensified. As you point out
such pipe systems 'must be both technically feasible and economically
justifiable in all cases.
Piped distribution systems, other than for sprinkler, are
generally employed for garden lands, which in the Damanganga case means
-2-
a considerable portion of mango, chikoo, coconut, plantain, vegetables,and possibly sugareane. A typical situation where pipeline wouldhwve advantage is the following:-
- Irregular micro-topography, with rolling slope 1.1/2%or moref but with irregularities sufficiently markedas to make smoothing out by land shaping difficult, anddistribution to the individual field (or individual treein some cases) by farm channel also difficult.
Desirability of supplying small streams to individualplots (e.g. vegetables) at frequest intervals withoutexcessive loss en-route, and unavailability of suchsupply through open unlined channels traversingneighbouring holdings.
- Small holdings. Cultivators are interested in developinginto high value garden crops, and soils are suitable.
The most effective distribution in the above circumstaroes, shortof buried pipe supply to each holding, is a buried pipe (a "main, stem"),e=taning dn through the centre of the outlet commA (up to 10 ha insize), and broadly in the direction of maximu slope (e.g. a 110 =n PVpipe on a 2%e slope). The pipe has valved outlets at 80 m to 100 m intervals.The outlets can supply at a head of 1 to 2 m above ground level. The pipetesinates at about 100 m short of the lower end of the outlet coa==d.
.croa the valved outlets the cultivators take water in turn
(or zhared turn) either by unlined field channel, or under low pressurevia cormzally o-ed or individually oumed hoses or "lAY flat" ar'is2itubes, or eventually via portable quick coupling pipe laterals (typically60 m to 70 m in length) with valved outlets for hoses. The laterals aremoved daily. Some cultivators may go as far as installing their ownburied laterals which can be coupled to the main stem.
The minimm initial construction could be the main stem, orpossibly the upstream one half of it, with outlets serving areas of about2 ha (one quarter of the 10 ha chak). The upper half of the chak wouldbe served by valved outlets at 80 to 100 ml the lower half by the lowermostoutlet of the interim half length main stem.
At final development a night-storage tank could be added adjacentto the main stem, at sane point doun its length.
It is noted.that the slope of the area, while of importance,is not taken as the primary criterion in the selection of location forpipe distributi=. Irregularity of topography and likelihood of developmentof garden crops" requiring close attention to irrigation are more importantfactors. As an illustration, an area of uniform slope of 46 and regulartopography could be supplied with water quite conveniently by open
(preferably lined) field chanel. Conversely it may be very difficult todistribute water within a chak of generally 1.1/2, slope, but very irregular,
-3-
without recourse to pipe. For canal supply :cstems there is nevertheless
a minimum slope below Vhich pipeline distribution would be uneconomic
in most circumstances. This limit depends upon size of chak and other
factors, but in the Damnganga case it is likely to be about 25 .
Apart frm the question of distribution br pipe or open channel,
Vol. 1 (.8) of the Appraisal Report prcvides that "the Goverment
would construct the chmmels do;u to each individual farm". ith this
requirment in view, and as discu-ssed this morning, it would be desirable
to carry out detailed designs of atercourse/farm chnnel systems on several
typical area.s of about 40 ha uainj a rege of different approaches (opench=nnol and pipe) and also considering staged development. With associatod
cost estimates this study could form the basis for discussion and adopticn
of aosii criteria,
