Description of the proposed project:The first task:” Description of the proposed project” forms a vital component of theEnvironmental Impact Statement (EIS) as it provides the basis for evaluating the likelycauses of Environmental Impacts. Land use issues dictate the significance of landloss/change. It is essential that the key components of the project shall be clearlydetermined as far as possible at this stage.

Assessment of Environmental Impacts:Based upon the results from the review of existing information, field visits, site datacollection and consultation, for each component of environment (physical, biologicaland socio economic) the positive, negative, direct and indirect, temporary andpermanent impact s will be evaluated along with an indication of the degree of impact,i.e., whether the impact is significant, moderate, minor or negligible.

Environment Management Plan and Mitigation Plan:For each significant negative impact identified, specialist shall work closely with theengineering team/technical consultants to suggest practicable measures to avoid ormitigate the impact. Suggestions for compensation shall be given where there is noother alternative course of action.

The mitigation of environmental impacts will be by three mechanisms.=>Introduction of mitigation features through the engineering practices.

=>Implementation of environmental controls during construction and operation.

=>Legislative control involving compliance with Indian environmental laws.

The Environmental management plan shall include an estimate of capital and recurringcosts of mitigation measures and will identify the parties and institutional frameworkfor implementation.

Monitoring Plan:Having identified the significant environmental impact that are likely to arise as a resultof the Residential villas construction project, the project team shall specify whatmonitoring is required during the various phases of the project cycle.The monitoring plan will identify parameters and frequency of monitoring andresponsible organization.

Sewage treatment plant based on Fluidized Aerobic Bio Reactor (FAB) technologyThe raw sewage will be collected in a collection sump and pumped to mechanical barscreen chamber for removal of large floating matter followed by grit removal in GritChamber. The raw sewage will then be collected in an equalization tank forhomogenization of hydraulic load. The tank contents will be kept in suspension bymeans of course bubble serration through pipe grid. The equalization tank, with air flowindicator for continuous monitoring of air supply to the tank in order to avoid septicconditions, will be covered from top (RCC or FRP) to avoid nuisance. The equalizedeffluent will then be pumped to two Fluidized Aerobic Bio Reactors (FAB) in serieswhere BOD/COD reduction can be achieved by virtue of aerobic microbial activities. Theoxygen required will be supplied through coarse air bubble diffusers. The bio-solidsformed in the biological process will be separated in the down stream Tube Settler. Theclear supernatant will gravitate to the chlorine contact tank where sodium hypochloritewill be dosed for disinfection of treated water prior to disposal.

The biological sludge generated in the FAB and settled in the tube settlers will becollected in a sludge sump and then pumped to sludge drying bed for de watering. Thedried sludge will then be disposed off suitably as manure. The schematics of the processare shown. The two main components of the treatment system viz. The FAB reactorand tube settler are described in the following sections.

Fluidized Aerobic Bio Reactor (FAB)Conventional effluent treatment plants are large sized, power intensive and require a lotof monitoring. Scarcity of open space and rising land a power costs have forced theindustries to look our for space saving, compact and efficient treatment options. Thishas led to the development attached growth processes where the bio mass is retainedwithin the aeration tank obviating the need for recycle. These plants are not onlycompact but also user friendly. The endeavor to have a continuously operating, no-clogging biofilm reactor with no need for back washing, low head-loss and high specificbiofilm surface area culminated in the most advanced technology of aerobic biologicalfluidized bed treatment where the biofilm (biomass) grows on small carrier elementsthat move along with the water in the reactor. The movement is normally caused byaeration in the aerobic version of the reactor.

The reactor combines all the advantages and best features of Trickling filters, Rotatingbiological contractors, activated sludge process and submerged fixed film reactors whileeliminating the drawbacks of these systems. The plants are more compact and moreenergy efficient.

The Fluidized Aerobic Bio Reactor (FAB) consists of a tank in any shape filled up withsmall carrier elements. The elements are made up of special grade PVC orpolypropylene of controlled density (shown in plate). For media of specific gravity 0.92-0.96 the overall density could be expected to increase up to 9.5% when full of biomasssuch that they can fluidize using an aeration device. A biofilm develops on the

A - 5

elements, which move along the effluent in the reactor. The movement within thereactor is generated by providing aeration with the help of diffusers placed at thebottom of the reactor. Then thin biofilm on the elements enables the bacteria to actupon the biodegradable matter in the effluent and reduce the BOD/COD content in thepresence of oxygen available from the air that is used for fluidization.

The sewage shall be treated and reused for flushing and on land irrigation. The treatedsewage shall meet the standards for disposal into surface water bodies, and hence thereshall not be any major additional load on the sewer lines, and may facilitate dilution of thesewage. The quantity of sewage expected is in the order of 34.79 KL/day.

2.7. Give details of the water requirements met from water harvesting? Furnish details ofthe facilities created.

The storm water drain would also ensure that the sedimentation does not occur, asrainwater harvestingstructures will alsohelp in controllingthe sedimentation.The rainwaterharvesting systemproposed wouldenhance the waterretention andincreases the watertable. The drainagewould in effectreduce the runoffand increase thepercolation. Thegradient of thechannel will bemaintainedthroughout its lengthso that water doesnot pond within it.Flows will bemaintained atvelocities that willscour the channel ofdebris. For instance,runoff velocities should not be less than 1 m/s nor should they exceed 3 m/s. Based onthe catchment area, potential inflows and rainfall intensity, determine the drain size so asto minimize damage resulting from high intensity storms. Energy dissipaters such as dropstructures will be provided along the channel where runoff velocities may becomeexcessive. The overflow from the storm water drains at rainwater harvesting structuresshall be provided with an overflow channel to drain into the roadside plantation which willact as a bios wale. Typical drawings of rainwater harvesting structures are presented forroof areas. The rainwater harvesting structures is presented below.

2.8. What would be the impact of the land use changes occurring due to the proposedproject on the runoff characteristics (quantitative as well as qualitative) of the area in thepost construction phase on a long term basis? Would it aggravate the problems offlooding or water logging in any way?The impact of housing project on physiography is a function of the terrain of the area. It ismost drastically altered in case of hilly terrain or where extensive cut-and-fill operationsare involved. The project area has a rocky terrain and the design stage deliberations haveensured that the major contours are not disturbed. However the physiography impact willbe significant and non-reversible, as the contours of the area will be disturbed. The cutand fill operations may cause air pollution, clogging of drains and solid waste for disposal.The design stage has optimized the cut and fill operations and the excess cut material isminimum and the same shall be reused for the construction purposes.The project will have a positive impact on the soils and soil quality as housing project willhave landscaping and the soils will be protected due to conservation.

During the occupation stage, compaction will not occur, and the compaction if any will berestricted to road ROW. And the road ROW compaction cannot be said to be an impact ofthe operation stage as the pavement itself is a function of compacted base and sub base.

During the occupation stage, soil pollution due to garbage dumping at unauthorizedlocations may have temporary negative impact leading contamination of soil. Theaccidental spills or leaks are also a low probability incident.

The other major impact will be due to the increased run off and may have negative impacton the receiving body if the same is not properly managed. Impacts due to surface runoffinclude increased soil erosion and local flooding or water logging. Hence the project will bedesigned with adequate storm water drains and cross drainage structures. The housingactivity will be provided with a Sewage treatment plant to treat the domestic wastewaterand necessary infrastructure will be provided for the safe disposal of domestic wastes toprotect the water bodies.

2.9. What are the impacts of the proposal on the ground water? (Will there be tapping ofground water; give the details of ground water table, recharging capacity, and approvalsobtained from competent authority, if any)Ground water shall be used as a secondary source during non-availability of water fromHMWSSB. The ground water table is at a depth of 10m to 15m

2.10. What precautions/measures are taken to prevent the run-off from constructionactivities polluting land & aquifers? (Give details of quantities and the measures taken toavoid the adverse impacts)Construction activity is taken up only during non-monsoon season. There are no majordrains in the site. All material dumps shall be located away from the natural drains.Storm water drains shall be constructed before the construction of the buildings.

2.11. How is the storm water from within the site managed?(State the provisions madeto avoid flooding of the area, details of the drainage facilities provided along with a sitelayout indication contour levels)Storm water drains will be provided all over the site to meet the expected increase in therunoff during rainy seasons due to the impervious nature of the roads and other paved

areas. It is proposed to maintain the levels as much as possible before letting storm waterinto side drains of main road.

Based on the catchment area, potential inflows and rainfall intensity, determine the drainsize so as to minimize damage resulting from high intensity storms. Energy dissipaterssuch as drop structures will be provided along the channel where runoff velocities maybecome excessive. The overflow from the storm water drains at rainwater harvestingstructures shall be provided with an overflow channel to drain into the roadside plantation,which will act as a bioswale.

Strom water drains: Storm water drains will be provided all over the site to meet theexpected increase in the runoff during rainy seasons due to the impervious nature of theroads and other paved areas. It is proposed to maintain the levels as much as possiblestorm water is letting into side drains of main road. The expected runoff is calculated forthe entire site is mentioned below.

Sewage treatment plant based on Fluidized Aerobic Bio Reactor (FAB) technologyPROCESS DESCRIPTION:The raw sewage will be collected in a collection sump and pumped to mechanical barscreen chamber for removal of large floating matter followed by grit removal in GritChamber. The raw sewage will then be collected in an equalization tank forhomogenization of hydraulic load. The tank contents will be kept in suspension by meansof course bubble serration through pipe grid. The equalization tank, with air flow indicatorfor continuous monitoring of air supply to the tank in order to avoid septic conditions, willbe covered from top (RCC or FRP) to avoid nuisance. The equalized effluent will then bepumped to two Fluidized Aerobic Bio Reactors (FAB) in series where BOD/COD reductioncan be achieved by virtue of aerobic microbial activities. The oxygen required will besupplied through coarse air bubble diffusers. The bio-solids formed in the biologicalprocess will be separated in the down stream Tube Settler. The clear supernatant willgravitate to the chlorine contact tank where sodium hypochlorite will be dosed fordisinfection of treated water prior to disposal.

The biological sludge generated in the FAB and settled in the tube settlers will be collectedin a sludge sump and then pumped to sludge drying bed for de watering. The dried sludge

F IA - 12

will then be disposed off suitably as manure. The schematics of the process are shown.The two main components of the treatment system viz. The FAB reactor and tube settlerare described in the following sections.

Fluidized Aerobic Bio Reactor (FAB)Conventional effluent treatment plants are large sized, power intensive and require a lotof monitoring. Scarcity of open space and rising land a power costs have forced theindustries to look our for space saving, compact and efficient treatment options. This hasled to the development attached growth processes where the bio mass is retained withinthe aeration tank obviating the need for recycle. These plants are not only compact butalso user friendly. The endeavor to have a continuously operating, no-clogging biofilmreactor with no need for back washing, low head-loss and high specific biofilm surfacearea culminated in the most advanced technology of aerobic biological fluidized bedtreatment where the biofilm (biomass) grows on small carrier elements that move alongwith the water in the reactor. The movement is normally caused by aeration in the aerobicversion of the reactor.

The reactor combines all the advantages and best features of Trickling filters, Rotatingbiological contractors, activated sludge process and submerged fixed film reactors whileeliminating the drawbacks of these systems. The plants are more compact and moreenergy efficient.

The Fluidized Aerobic Bio Reactor (FAB) consists of a tank in any shape filled up with smallcarrier elements. The elements are made up of special grade PVC or polypropylene ofcontrolled density (shown in plate). For media of specific gravity 0.92-0.96 the overalldensity could be expected to increase up to 9.5% when full of biomass such that they canfluidize using an aeration device. A biofilm develops on the elements, which move alongthe effluent in the reactor. The movement within the reactor is generated by providingaeration with the help of diffusers placed at the bottom of the reactor. Then thin biofilmon the elements enables the bacteria to act upon the biodegradable matter in the effluentand reduce the BOD/COD content in the presence of oxygen available from the air that isused for fluidization.

9.4. What passive solar architectural features are being used in the building? Illustratethe applications made in the proposed project.

The width to height ratio between the villa units is around 1:1.5 which is achievedas per the development control rules.

All window openings is provided with chajjas depth as specified by the designstandards (around 300mm)

9.5. Does the layout of streets & buildings maximize the potential for solar energydevices? Have you considered the use of street lighting, emergency lighting and solar hotwater systems for use in the building complex? Substantiate with details.

Solar power shall be used for the community center for both water heating and lightingrequirement.

9.6. Is shading effectively used to reduce cooling/heating loads? What principles havebeen used to maximize the shading of Walls on the East and the West and the Roof?How much energy saving has been effected?

Yes, the apartment blocks are aligned north and south to maximize the shading.

9.7. Do the structures use energy-efficient space conditioning, lighting and mechanicalsystems? Provide technical details. Provide details of the transformers and motorefficiencies, lighting intensity and air-conditioning load assumptions? Are you using CFCand HCFC free chillers? Provide specifications.

Building Materials The building materials chosen for the landed and apartment units are as per the

recommendations of the climatic standards. To achieve the maximum energy value, a balance between the availability of

building materials locally and skilled labourers is achieved. Burnt brickwork with fly ash for the walling and plastering reduces the thermal

penetration by 20-30%.

Colour of Facades The colour choice for the buildings uses a maximum of white surface (nearly 84%).

This increases the solar reflectivity factor. Emittance factor for white surfaces is around 90% compared to coloured surface

(20-60%) 16% of wall area uses earthen colours and this space has longer thermal storage in

the walls. This creates a comfortable temperature at nights due to the thicker wallsdesigned.

Heat Absorbance of the brick used for building is around 50%. The roof of the units (if not covered with terrace garden) is painted white to have a

maximum reflectivity. The R-factor (resistance factor) for the roof with brickbats and white painted is

nearly 40% more as compared to the recommended standards.

9.8. What are the likely effects of the building activity in altering the microclimates?Provide a self-assessment on the likely impacts of the proposed construction on creationof heat island & inversion effects?Green RoofsGreen roofs are an attractive roofing option that can reduce urban heat islands byproviding shade and through evapotranspiration, the release of water from plants to thesurrounding air. The benefits of green roofs include:

Reduce sewage system loads by assimilating large amounts of rainwater. Absorb air pollution, collect airborne particulates, and store carbon. Protect underlying roof material by eliminating exposure to the sun's ultraviolet

(UV) radiation and extreme daily temperature fluctuations. Serve as living environments that provide habitats for birds and other small

animals. Offer an attractive alternative to traditional roofs, addressing growing concerns

about urban quality of life. Reduce noise transfer from the outdoors. Insulate a building from extreme temperatures, mainly by keeping the building

interior cool in the summer.

9.9. What are the thermal characteristics of the building envelope? (a) Roof; (b) Externalwalls; and (c) Fenestration? Give details of the material used and the U-values or the R-values of the individual components.NA

9.10. What precautions & safety measures are proposed against fire hazards? Furnishdetails of emergency plans.NA
