In specification 40 72 00 Level Instrumentation Devices add the following paragraph:

2.03 LEVEL TRANSMITTER - SUBMERSIBLE PRESSURE TYPE

A. Subject to compliance with the Contract Documents, the following Manufacturers are

acceptable:

1. Measurement Specialties MEAS KPSI 705 Submersible Transmitters for hydrostatic Level

2. No Equal

B. The listing of specific manufacturers above does not imply acceptance of their products that

do not meet the specified ratings, features and functions. Manufacturers listed above are

not relieved from meeting these specifications in their entirety.

C. General

1. Type: Measuring level by continuously measuring hydrostatic pressure via its sensing

element, Data is transmitted by an analog, 4 to 20 mA DC output signal.

D. Performance Requirements:

1. Accuracy: ±0.25 percent full scale.

2. Zero Offset: ±0.50 percent full scale minimum configurable.

3. Span: ±0.50 percent full scale minimum configurable by manufacture.

4. Operating Temperature Ranges: -20 to 60 degrees C.

E. Construction Features:

1. Sensor: Type 316 stainless steel.

2. Housing: Type 316 stainless steel.

3. Cable shall be provided of required length and fully submersible construction.

4. Power supply: 9 to 28 VDC with surge and lightning protection.

5. Electrical Connection: Attached 4-wire, 22AWG Conductors in a shielded cable with

vent tube and polyurethane outer jacket.

In specification section 40 78 00 Panel Mounted Control Devices add the following to paragraph 2.08 A.:

4. Siemens model RD200

In specification 40 61 96 Control Loop Descriptions replace paragraphs 3.02 and 3.03 with the following:

3.02 PUMP STATION

Following loops are associated with the new Pump Station. The Data Flow Systems RTU (PLC as

indicated on the drawings) shall be programmed with the following as described below.

A. Loop 600 Booster Pump Station

1. General: Series of float switches shall be installed as shown in the drawings The Low-

level Float shall be an interlock for both pumps. The pumps shall alternate, and the PLC

shall provide an indication to the OIT which pump is the lead pump.

2. GRANULAR ACTIVATED CARBON (GAC) filtration system permissive based on maximum

flow limits are provided as hardwired signals. These include YL-410 PV-1 and PV-2 IN

series, YL-420 PV-3 and PV-4 in Series, YL-411 PV-1 in Service, YL-412 PV-2 in service, YL-

421 PV-3 in Service and YL-422 PV-4 in service.

a. The maximum flow rate for all CAG units in service shall not be exceeded. By

monitoring these status points the maximum flow can be calculated.

b. The flow meters for each unit are interfaced to the pump control PLC as indicated

on the drawings.

c. If the YL-410 signal is true, then the flow from FI-301 will be the flow for the series

filter units PV-1 and PV-2.

d. If the YL-420 signal is true than the flow FI-303 be the flow for the series filter units

PV-3 and PV-4.

e. The flow through the CAG filters is the total of the in-service units by utilizing flow

meters minus

f. The maximum speed of the pump VFD shall be dynamically caped in automatic

mode to not exceed the max flow rate for the available CAG filters in their current

mode configuration.

3. Field Instruments: The High-Level float shall call for both pumps to run. The High float

shall start the lead pump. When the level reaches the low float, the pump shall stop,

and the pumps shall alternate.

4. Permissive include the level above the low-level float and a good level indication as

measured from the LIT-600 4-20mA signal transmitter.

5. The pump station shall operate pumping capacity to maintain a level setpoint within a

narrow dead-band as entered from the pump station control panel OIT. The VFD’s shall

operate from the minimum speed as determined by the pump curve from the pump

supplier to 100% speed. If the lead pump cannot maintain the level within range and is

operating at greater than 98% for a configurable delay, then the Lag pump shall be

called to run, and both pumps run at near the same speed. If both pumps are running

and the level is below the setpoint for a configurable delay time than the Lead pump

should be called to stop. The Lag becomes the Lead pump.

6. On a weekly basis the Lead shall become Lag and Lag become Lead as at least one pump

will be running continually in normal operation. This rotation will allow for more equal

utilization of pumping equipment.

B. HMI Control and Monitoring

1. This system should be incorporated into the Plant SCADA system as part of the CAG

(GRANULAR ACTIVATED CARBON) Filter System Displays

a. Indications and status as shown within the plans are to be included as a minimum.

3.03 GRANULAR ACTIVATED CARBON (GAC) FILTRATION SYSTEM

A. The CAG filtration system will run autonomously from the plant SCADA and shall be

controlled by the CAG system manufacturer supplied control system. This control panel is to

be installed on the MCC-1 platform as shown on the drawings.

B. Indications and statuses as shown on the plans are to be hardwired from the CAG control

Panel to the Data Flow Systems RTU (PLC as indicated on the drawings) panel as shown.

These signals are to be incorporated into the existing plant SCADA HMI for monitoring and

reporting

1. Individual flow meters are to be displayed and a Filter to Waste flow is to be calculated

within the GAC Manufactures control panel and made available to the plant SCADA

system as a hardwired indication. This signal is to assure all State of Texas reporting

requirements are meet.

2. Calculated signals to indicate in service shall be true when the filter unit is producing

filtered water regardless of parallel or series mode. The arrangement indication for

series mode shall also be made available.

C. The total flow through the CAG filter units shall be balance to the units that are currently in

service. The influent valve shall modulate to control the flow to achieve this balance and

protect the filters against exceeding the maximum flow rate.

The following plan sheets are replaced:

E-4, E-7, E-9, E-11, E-12, E-13, E-14, E-15, E-16, E-17, E-18, E-19, E-20, E-22, E-23, I-2, I-3, I-4, I-5

underlying surface. Coated surfaces must be totally free of all roller nap, roller marks, brush

bristles and brush marks.

O. When using conventional coating spray equipment for coating operations, effective oil and

water separators combined with after coolers or deliquescent dryers must be used in

compressed air lines to remove detrimental oil and moisture from the air. Separators must

be placed as far as practical from the compressor. Compressors may be tested periodically

by the Owner’s representative for oil and water contamination of compressed air. Testing

must follow ASTM D4285 “Standard Test Method of Indicating Oil and Water in Compressed

Air.” All compressor units found to produce unacceptable amounts of oil and or water, as

determined by results of ASTM D4285 test data and interpretation of data by the Owner’s

representative must be replaced with a compressor that is acceptable.

P. For porous surfaces, such as concrete or masonry, a prime coat may be thinned to provide

maximum penetration and adhesion. The type and amount of thinning must be determined

by the coating manufacturer and is dependent on surface density and type of coating.

1.05 DELIVERY AND STORAGE

A. Packing:

1. The pipe shall be prepared for shipment to afford maximum protection from normal

hazards of transportation and allow pipe to reach the Site in an undamaged condition.

Pipe damaged in shipment shall not be delivered to the Site unless such damaged pipe is

properly repaired.

2. After the completed pipe and fittings have been removed from the final cure at the

manufacturing plant, the pipe lining shall be protected from drying by means of plastic

end covers banded to the pipe ends. Covers shall be maintained over the pipe ends at

all times until ready to be placed in the trench. Moisture shall be maintained inside the

pipe by periodic addition of water as necessary.

3. Pipes shall be carefully supported during shipment and storage. Pipe, fittings, and

specials shall be separated so that they do not bear against each other, and the whole

load shall be securely fastened to prevent movement in transit. Ship pipe on padded

bunks with tie-down straps approximately over stulling. Store pipe on padded skids,

sand or dirt berms, tires, or other suitable means to protect the pipe from damage. As a

minimum, each end of each length of pipe, fitting, or special and the middle of each

pipe joint shall be internally supported and braced with stulls to maintain a true circular

shape. More internal stulls shall be included to protect the pipe, lining, and coating

from damage as determined by the Pipe Manufacturer. Internal stulls shall consist of

timber or steel firmly wedged and secured so that stulls remain in place during storage,

shipment, and installation. Pipe and liner shall be protected from damage from stulls

using shaped wood pads or similar devices. Stulls shall not be welded directly to the

pipe except at the end of the pipe where the lining is held back. Pipe shall be rotated so

that one stull remains vertical during storage, shipment and installation. Stulls shall not

be removed until the pipe is laid, set to grade, and backfilled.

4. Deliver, handle, and store pipe in accordance with the Manufacturer's

recommendations and in accordance with Paragraph 3.01.C.

B. Marking for Identification: Each joint of pipe and each fitting shall have plainly marked on

the inside of both ends, the class for which it is designed, the date of manufacture, and the

identification number as shown on the Shop Drawings. Beveled pipe shall be marked with

the amount of bevel. The top centerlines shall be marked on all specials.

C. Point of Delivery:

1. Pipe shall be hauled direct from pipe plant to the Site and strung along pipeline route,

thus avoiding re-handling of pipe and the possibility of damage thereto. Where fully

loaded truck and trailer cannot operate along the pipeline route, pipe may be unloaded

at access points along the route, and brought to the trench side by approved methods;

however, the Contractor shall be responsible to ensure that pipe is undamaged at the

time of laying.

2. If the pipe cannot be hauled directly from the pipe plant to the laying site, a maximum

of two handlings is allowed in which case the maximum number of coating repairs is

reduced to five.

3. Shipment by rail will be unacceptable, unless it can be demonstrated that it will not

damage the pipe.

A. General: Butterfly valves supplied under this Contract shall be of the tight-closing, rubber

seated type with rubber seats that are securely attached to the valve disc or body. Valves

shall be bubble tight at rated pressures with flow in either direction and shall be satisfactory

for applications involving valve operation after long periods of inactivity. Butterfly valves

shall conform to the applicable requirements of AWWA C504 and AWWA C550. All valves

for potable water service shall comply with NSF61 standards.

B. Valve Bodies: Valve bodies shall be constructed of cast iron ASTM A126, Class B or ASTM

A48, Class 40 or ductile iron in accordance with ASTM A536, Grade 65/45/12. Valve class

shall be suitable for the pressure class of the adjacent pipe in which it is installed. Valve may

have flanged ends with ANSI B16.1 Class 125 drilling or be of the wafer body style and be

suitable for use between ANSI B16.1 Class 125 cast iron flanges.

C. Valve Discs: Valve discs shall be cast iron conforming to ASTM A126, Class B, aluminum

bronze conforming to ASTM B148, or ductile iron conforming to ASTM A536, Grade

65/45/12.

D. Valve Shafts: Valve shafts shall be turned, ground and polished, constructed of stainless

steel conforming to ASTM A276. Valve shafts may consist of a one-piece unit extending

completely through the valve disc, or may be of the “stub shaft” type, which comprises two

separate shafts inserted into the valve disc hubs. If of the “stub shaft” construction, each

stub shaft shall be inserted into the valve disc hubs for a distance of at least 1-1/2 shaft

diameters. The shaft shall be tightly connected to the disc using tapered or wedged keying

devices.

ADDENDUM NO. 3



E. Valve Seats: Valves shall have Neoprene, Buna-N or other synthetic rubber resilient seas to

provide tight shut off at the pressure specified. The mating seat surface shall be ASTM

A276, 18-8 stainless steel or a 95 percent pure nickel overlay. All valves shall have

replaceable, adjustable seats. Valves 30 inches and larger shall have in-line replaceable

seats.

F. Valve Bearings: Valve shall be fitted with sleeve type bearings. Bearings shall be of

corrosion-resistant and “self-lubricated” materials that will not deteriorate natural or

synthetic rubber.

G. Valve Shaft Seals: Where shafts project through the valve bodies for operator connection, a

split-V or O-ring type shaft seal shall be provided.

H. All components, including seats, seals and gaskets, for use with the aeration or backwash air

system shall be suitable for 300-degree F service.

2.02 VALVE OPERATORS:

A. General: The valve operator shall be designed and manufactured in accordance with the

applicable requirements of AWWA C504 and AWWA C540, and shall be arranged for

horizontal or vertical valve shaft installation.

B. Manual Operators:

1. Manual operators shall have all gearing totally enclosed and shall be pre-lubricated or

grease packed. Operators shall be of the worm gear or travelling nut and link type with

field adjustable stops to prevent over travel in the open or closed positions. The

direction of the manual rotation shall be clockwise to close.

2. Operators for exposed valves shall be provided with a valve position indicator and a

handwheel or chain and sprocket device. Provide chain and sprocket for valves greater

than 6-feet above walking surface. Chains must be galvanized and loop within four feet

of the floor.

3. Operators for buried valves shall have an extended stem with a 2-inch square operating

nut within 12 inches of the finished grade. Provide a cast iron valve box to enclose the

operating stem. Valve box shall be per City of Kerrville Standard 370.06 with concrete

collars.

4. For valves which are installed with the shaft vertical, provide a level gear for vertical

operation of the operating nut.

C. Electric operators are to be provided per specification 46 07 13 “Adsorption Systems for use

with Granular Activated Carbon.”

2.03 BUTTERFLY VALVES FOR AIR SERVICE

Furnish lugged style butterfly valves for air service. Valves 10 inches and smaller shall have a

ten-position locking lever operator. Valves 12 inches and larger shall have a gear type hand-

wheel operator. The valve shall be resilient seated, bubble-tight shut off. The valve shall be

shipped loose for field installation. Valve seats and gaskets shall be suitable for operation in

temperatures up to 300-degrees F.

3.00 EXECUTION

3.01 INSTALLATION

Installation shall be in accordance with the Manufacturer’s instructions. Valve shaft shall be

truly vertical or horizontal as indicated.

3.02 FIELD QUALITY CONTROL

Upon completion of installation of the butterfly valves an acceptance test shall be conducted to

verify the satisfactory operation of the valves. The valves must perform in a manner acceptable

to the Engineer before final acceptance will be made by the Owner.
