The Autocoupling discharge flange shall be ANSI Class 125 size_ inch Cast Iron . PERFORMANCE GUARANTEE The pump shall be designed to handle raw, unscreened sewage, storm water, sludge or similar contaminated liquid at a operating point of J_Q_ GPM at di. 8' FT TOH with a Hydraulic Efficiency of at least 'J.Jl....%. Shut-off head shall be ~ FT minimum. As this pump will be utilized for solids handling, it must be capable of repeatably passing spherical sol ids up to inch in diameter. MATERIALS OF CONSTRUCTION Major castings : ASTM A48 Class 40B Cast Iron . -Wear Ring : ASTM Bl44 Bronze. -Shaft: AISI 430F Stainless Steel. - Fasteners: AISI 304 Stainless Steel. -0 -Rings : Nitrile Rubber. -Shaft Seals : Silicon Carbide/Silicon Carbide (impeller and motor side). Cable Jacket: Neoprene . -Cable Entry: elastomer grommet, stainless steel washers.-Protective Coating (on outside surface): High Solids Epoxy IMPELLER Impeller will be cast as one piece and shall be one of the following designs: (~ single-vane closed (double-shrouded). radial non-clog ("AM " & "AMX " Models) ( ) two-vane closed (double-shrouded), radial non-clog ("AK" Models) ( ) multi-vane open (single-shrouded}, torque-flow (vortex, 4" and 6" "AV' models) statically and dynamically balanced , to assure that vib ration amplitudes, measured at the level of the upper bearing while operating in a vertical position , remain within the limits specified by the Hydraulic Institute Standards. • VOLUTE Volute will be cast in one piece, with smooth internal contours and surfaces, providing obstruction-free passageways with low friction losses . A stationary Wear Ring, made of bronze , shall maintain close tolerances between the rotating Impelle r and the stationary Volute . • SHAFT • Pump shaft must have generous shoulder fillet radii to minimize stress concentration and fatigue. Deflection at the Shaft Seal within the operating range shall not be more than 0 .002 inch . BEARINGS Pump shaft shall be supported by anti-friction bearings, designed for 50,000 hours B-10 Life at the pumps Best Efficiency Point ,and shall be factory pre-lubricated for life. The lower impeller-side bearing will be a double-row, deep groove ball bearing, ax ially retained, to sustain both axial and radial !oads . The upper motor-end beari:1g is a single-row, deep groove ball bearing axially floating, to sustain radial loads only . .... Cont. • WATERTIGHT INTEGRITY The watertight integrity of the single-body pump-motor assembly shall be assured . The Cable Entry shall contain an elastomer grommet, flanked by two washers, closely fitted to the cable O.D. A watertight seal shall be maintained by screwing a threaded gland down to a positive stop (metal-to-metal, to prevent permanent deformation by overtightening), thereby tightly compressing the grommet around the cable. The gland will provide a strain-relieving , anti-kink feature, functioning independently from the separate sealing action . For pumps above 30 horsepower an isolated Junction Box containing the Terminal Board, and sealed from the Motor Compartment by a watertight isolation plate, will provide a secondary barrier against water or moisture penetration . Each pump shall be supplied with 30 feet of SO Type power cable. • SEALS Motor Compartment shall be isolated from the Liquid End by Single Mechanical Shaft Seals in tandem arrangement (dual- independent, both oriented to resist pressure from the impeller). The upper motor side seal shall run in an Oil Chamber, which separates the Motor Compartment from the Liquid End and provides permanent lubrication and cooling. The lower impeller side seal will also get lubrication from the Oil Chamber. Each seal will have a stationary portion and a positively driven rotary portion . Springs must be protected from the pumped liquid; and under no circumstances can solid particles accumulate on the external spring and hamper its effectiveness . Seals must not require repeated checking or re-adjustment, except periodic inspection of the oil chamber. At the interfaces of major castings, sealing shall by accomplished by resilient Buna-N 0-Rings, confined within closely fitted, high surface quality rabbet joints, compressed only to the prescribed dimension by metal-to-metal contact , allowing radial movement and preventing permanent set. Flat gaskets and seal rings , which may be squeezed unevenly or beyond the permanent deformation limit, are not allowed . • SEAL PROBE • • A single wire, conductive seal probe shall be provided with pump. Probe shall be mounted into mechanical seal chamber and shall be accessible without disassembly of pump. When interlocked with control panel , probe shall indicate the presence of contaminants within mechanical seal chamber. ELECTRIC MOTOR Each pump shall be driven by a Submersible Squirrel Cage Induction Motor, rated a~ HP 11,ZQ_RPM..:tkQ.Voltsd_ Phase . Motor shall be NEMA Design B for continuous duty, capable of sustaining a minimum of 10 starts per hour. The pump and motor shall be produced by one manufacturer and shall be of the air-filled , watertight design. All stator windings and leads shall be insulated with moisture-resistant Class F Insulation , capable of withstanding 155°C Max . temperature , dipped and baked three times . Upon assembly the stator shall be heat-shrink-fitted into the stator housing; the use of bolts, pins or other fastening devices, which would require penetration of the stator housing , shall not be acceptable . In each phase winding there shall be embedded a bi-metallic temperature sensor, wired in series and interlocked with the motor overload protection in the Control Panel. Any of these thermal sensors shall cut out electric power if the temperature in its winding exceeds 140°C, but shall automatically reset when the winding temperature returns to normal. The motor shall be non- overloading through the selected performance curve and have a Service Factor of l.15. When the application requires, motor shall be approved for use in Hazardous (Classified) areas. Pumps shall be suitable for operation in Class 1, Division 1, Groups C & D Areas only, and shall be approved by Factory Mutual (FM) for use in the area classification indicated. Seal leak probe, if required, shall be dual wire . All FM approved pumps supplied for use in Hazardous areas shall be supplied with an isolated junction box as described above . INSTALLATION MODE An Autocoupling assembly shall be employed to eliminate the need for entering the wet well to service pumps . The system shall allow the lowering of the pump unit(s) into the well along rigid gu ide pipes , resulting in a self-engaging, firm, leakproof coupling of the volute outlet to a receiving Base anchored to the floor which forms the discharge pipe connection. To assure a leakproof junction between movable and stationary components , a resilient seal ring shall be employed which is easily replaceable as part of the pump assembly, is axially and evenly compressed upon contact. Metal-to-metal contact faces shall not be allowed . Once seated, the pump shall be entirely supported by the Autocoupling Base , without any reliance on additional supports .

The Contractor shall provide and install any sheeting , shoring, and bracing as necessary to provide a safe work area as required to protect workmen, structures, equipment, power poles, etc. The Contractor shall be responsible for the design and adequacy of all sheeting, shoring, and bracing. The sheeting, shoring, and bracing shall be removed as the ex cava tion is backfilled in such a manner as to prevent injurious ca ving . I I ,, 'i /' SLOPING SIDES: Where sufficient space is available, the Contractor shall be allowe d to back slope the sides of the excavation . The back slope shall be such that the excavation shall be safe from caving . The type of material being excavated shall govern the back slope used, but in any case the back slope shall be no steeper than 1 foot horizontal to 1 foot vertical . DEWA TERING: The Contractor shall keep the excavation free from water by use of cofferdams, bailing, pumping, well pointing, or any combination as the particular situation may wa rrant. All dewatering devices shall be installed in such a manner as to provide clearance for construction, removal of forms, and inspection of exterior of form work . It is the intent of these specifications that the foundation be placed on a firm dry bed. The foundation bed shall be kept in a dewatered condition a sufficient period of time to insure the safety of the structure. All dewatering methods and procedure are subject to the approval of the Engineer. The excavation shall be protected from excessive ra infa ll, drainag e and d rying . The excavation sh all be inspected and approved by the Engine er before work on the structure is started. It is the intent of these specifications that the Contra.ctor provide a relatively smooth, firm foundation bed for footings and slabs that bear directly on the u'hdisturbed earth without addition al cost to the Owner, regardless of the soil conditions encountered. The Engineer will be the sole judge as to whether these conditions have been met. The contractor shall pile excava ted material in a manner that will not endanger the work. UNAUTHORIZED OVER EXCAVATION: Ex cavation for slabs, footings, etc ., that bear on earth shall not be carried below the elevation sho wn on the drawings . In the event the excavation is carried on below the indicated elevation, the Contractor shall bring the slab, footing , etc ., to the required grade by filling with concrete having a minimum compressive strength of at least 3,000 PSI at 28 days . HANDLING: Do not drop or impact the wet well. Wet wells shall be chocked if stored horizontally. If wet wells must be moved by rolling , the ground transversed shall be smooth and free of rocks, debris, etc. FRP wet wells may be lifted by the installation of two lifting lugs as specified by the manufacturer on the outside surface near the top or by a sling or "choker" connection around the center. Use of chains or cables in contact with the wet well surface is prohibited. Wet wells may be lifted horizontally using one support point. OPEN BOTTOM WET WELL INSTALLATION: Bottom of excavation should be compacted to 95% Standard Proctor Density. Pour reinforced concrete base one foot deep and at least two feet larger than the fiberglass wet well outside diameter. As soon as the concrete has set-up enough to support the fiberglass wet well, lower the wet well into place . Pour a minimum of one foot of reinforced concrete on the inside , also a minimum of one foot deep and two feet from the fiberglass wet well wall on the outside of the wet well.

Wet wells with diameters 72 inches or less require a base of 6 inches of crus hed stone. Wet wells with diameters larger than 72 inch should have poured reinforced concrete base one foot deep and at least two feet larger than fiberglass wetwell outside diameter. As soon as the concrete has set-up enough to support the fiberglass wetwell, lower the wetwell into place . Place lag bolts or rebar through anti-flotation flan ge or hold down lugs . Pour reinforced concrete a minimum of one foot deep and two feet from outside wall of the wetwell. More concrete may be required in high water table areas. In high water table areas you should consult your Engineer for backfill requirements. FIBERGLASS WETWELL TOP: The fiberglass top may have stubouts installed or may have a raised fiberglass collar around the hatcf1 opening. The fiberglass top has been designed to withstand the weigh of a concrete reinforced slab to be installed over it. BACKFILL: BACHFILL MATERIAL: Unless shown otherwise on the drawings, sand or crushed stone shall be used for backfill around the wet well for a distance of two feet from the outside surface and extending from the bottom of the excavation to the bottom of the top slab . Suitable material chosen from the excavation may be used for the remainder of the backfill. The material chosen shall be free of large lumps or clods, which will not readily break down under compaction . This material will be subject to approval by the Engineer. Backfill material shall be free of vegetation or other extraneous material. Excavated materials which are to be used for fill or backfill may be stockpiled on the site. Location of stockpiles shall be approved by the Engineer. Top soil should be stockpiled separately and used for finish grading around the structure . SCHEDULE OF BACKFILLING: The Contractor may begin backfilling of wet well as soon as the concrete has been allowed to cure and the forms removed . BACKFILL LIFTS: Backfill shall be placed in layers of not more than 12 loose measure inches and mechanically tamped to at leas t 95% Standard Proctor Density. Flooding will not be permitted. Backfill shall be placed in such a manner as to prevent any wedging action against the structure .

The project site is located just southwdt of Old Wellborn Road along Rock Prairie Road beginning 1,059 feet southwest of Old Wellborn Road. The proposed tie to the existing system is an 8" line located northeasX; of Old Wellborn Road in the Edelweiss Estates/Business Area. This tie lies within th'; boundary of the Sanitary Sewer Area 92-01 . Analysis of Proposed Sewer Flow: Williamsgate Subdivision is classified for residential land use and consists of 20.27 acres with 82 proposed lot~. Using the Land Use Determination Method of flow from the 2004 Bryan/College Statio~ Uniform Design Guidelines , the flow for the proposed site was estimated. The peak !flow was calculated by multiplying the Average Daily Flow by 4 .0 . The estimated flow fbr Williamsgate Subdivision is 21,894 gpd with a peak flow of 61 gpm. Lift Station: The proposed lift staifon to be used in the Williamsgate subdivision is a Duplex 4: Non- Clog Lift Station (mqdel # -BPSRA40-72240VBS). This model runs on two Myers 4" non-clog submersiblei pumps which allows a minimum of a 3 " solid to pass. The wet well used for the lift! station is fiberglass reinforced polyester, and, because it is a wet well, odor ventilatioti is reached through a vent located at the top of the well (no mechanical ventilation. is required). Also , each pipe leading away from the pumps have check valves at its di~charge. · After basing specifications on Chapter 317 .3 of the Design Criteria for Sewerage : Systems, the Williamsgate Duplex 4" Non-Clog Lift Station meets the requirements . Sanitary Sewer Service Area 92-01 Capacity: The proposed tie-in location is within the boundaries of the 92-01 Service Area. Flow capacity data for thi$ area was obtained from TEXCON's "Sanitary Sewer Analysis, Impact Fee Service ftirea 92-01 for Dove Crossing Subdivision Phases 1" dated October 2004 . This analysis ~valuated the land use areas of the 92-01 Service Area and the area served by the 18" sanitary sewer line which discharges into the lift station near State Highway 6 . Four land use areas with a total area of 20 .6 acres serve the 8" line at the tie-in location. These areas include :retail , office, commercial, and church. The TEXCON analysis estimated the total floiw from these four land use areas to be 25,259 gpd with a peak flow of 18 gpm. Using a I!lomograph with the minimum required slope for an 8" pipe , it was estimated that the 8" Hne has a capacity of359 gpm with a velocity of 2 .6 fps. 02 /11 /2005 16:18 FAX 979 764 3452 COLLEGE STATION PUB.UTL. ~ WWTP 141003 The TEXCON analy$is estimated that a total flow of 665,556 gpd with a peak flow of 1,849 gpm dischargeid from the 18" sewer line into the lift station. The analysis also determined that the IS" line has a capacity of 2213 gpm with a velocity of 3 .1 fps . Results: The 8" line at the tie-hi is currently at 5% capacity. The capacity including the flow from Williamsgate would be 22%. The capacity of the 18" line is currently 70%. With the additional flow from . Williamsgate, the capacity would be 86%. The existing sanitary sewer line has adequ~e capacity for the development of Williamsgate Subdivision.

TYPE 3: Install Insert-A-Tee type fitting per manufacturers instruction. (Fowler Mfg . Co ., P.O . Box 767 , Hillsboro , Or. 97123. PH . 503-359-5417) or approved equa l. CLOSED BOTTOM WETWELL INSTALLATION: Bottom of excavation should be compacted to 95% Standard Proctor Density. Wetwells with diameters less than 60 inches and depths less than 12 feet, require a base of 6 inches of crushed stone . Wetwells with diameters of 60 inches and larger and depths of 12 feet and greater, should have a poured reinforced concrete base at least one foot deep and at least two feet larger than fiberglass wetwell outside diameter. The fiberglass wetwell shall be lowered into the wet concrete and brought to plumb. Pour reinforced concrete over the anti-flotation flange . The concrete shall be a minimum of one foot deep and two feet from outside wall of the wetwel l. More concrete may be required in high water table areas . In high water table areas you should consult your Engineer for backfill requirements . INTERNAL BOTTOM RIBS: Wetwells with internal bottom stiffening ribs will require that concrete be poured on the inside of the wetwell to a depth equal to that of the stiffening ribs . This is typically 4-6 inches. FIBERGLASS WETWELL TOP: The fiberglass top may have stubouts installed or may have a raised fiberglass collar around the hatch opening . The fiberglass top has been designed to withstand the weight of a concrete reinforced slab to be installed over it. BACKFILL: BACKFILL MATERIAL: Unless shown otherwise on the drawings, sand or crushed stone shall be used for backfill around the wetwell for a distance of two feet from the outside surface and extending from the bottom of the excavation to the bottom of the top slab. Suitable material chosen from the excavation may be used for the remainder of the backfill. The material chosen shall be free of large lumps or clods , which will not readily break down under compaction . This material will be subject to approval by the Engineer. Backfill material shall be free of vegetation or other extraneous material. Excavated materials which are to be used for fill or backfill may be stockpiled on the site. Location of stockpiles shall be approved by the Engineer. Top soil should be stockpiled separately and used for finish grading around the structure. SCHEDULE OF BACKFILLING: The Contractor may begin backfilling of wetwell as soon as the concrete has been allowed to cure and the forms removed . BACKFILL LIFTS: Backfill shall be placed in layers of not more than 12 loose measure inches and mechanically tamped to at least 95% Standard Proctor Density. Flooding will not be perm itted . Backfill shall be placed in such a manner as to prevent any wedging action against the structure . TOP SLAB SUPPORT: When installing a fiberglass wetwell w ithout a fiberglass top you should pour a reinforced concrete slab support a minimum of two feet outside of fiberg lass wetwell wall and a minimum of six inches thick . The slab shall be specified and designed by project engineer. MARKING AND IDENTIFICATION: Each wetwell shall be marked with the following information . (1) Manufacturer's name or trademark (2) Manufacturing special number (3) Total length and nominal diameter 4 S:\SpecDsk\Specificalio ns\Wetwell Spec.rt! Rev .6 9~2 and bracing . The sheeting, shoring , and bracing shall be removed as the excavation is backfilled in such a manner as to prevent injurious caving. SLOPING SIDES: Where sufficient space is available , the Contractor shall be allowed to back slope the sides of the excavation. The back slope shall be such that the excavation shall be safe from caving . The type of material being excavated shall govern the back slope used , but in any case the back slope shal l be no steeper than 1 foot horizontal to 1 foot vertical. DEWATERING: The Contractor shall keep the excavation free from water by use of cofferdams , bailing , pumping , well pointing, or any combination as the particular situation may warrant. All dewatering devices shall be installed in such a manner as to provide clearance for construction, removal of forms , and inspection of exterior of form work. It is the intent of these specifications that the foundation be placed on a firm dry bed. The foundation bed shall be kept in a dewatered condition a sufficient period of time to insure the safety of the structure. All dewatering methods and procedures are subject to the approval of the Engineer. The excavation shall be protected from excessive rainfall, drainage and drying. The excavation shall be inspected and approved by the Engineer before work on the structure is started . It is the intent of these specifications that the Contractor provide a relatively smooth, firm foundation bed for footings and slabs that bear d irectly on the undisturbed earth without additional cost to the Owner, regardless of the soil conditions encountered . The Engineer will be the sole judge as to whether these conditions have been met. The contractor shall pile excavated material in a manner that will not endanger the work. UNAUTHORIZED OVER EXCAVATION: Excavation for slabs, footings, etc ., that bear on earth shall not be carried below the elevation shown on the drawings. In the event the excavation is carried on below the indicated elevation, the Contractor shall bring the slab, footing, etc ., to the required grade by filling with concrete having a minimum compressive strength of at least 3,000 psi at 28 days. HANDLING: Do not drop or impact the wetwell. Wetwells shall be chocked if stored horizontally. If wetwells must be moved by rolling , the ground transversed shall be smooth and free of rocks, debris , etc. FRP wetwells may be lifted by the installation of two lifting lugs as specified by the manufacturer on the outside surface near the top or by a sling or "choker" connection around the center. Use of chains or cables in contact with the wetwell surface is prohibited . Wetwells may be lifted horizontally using one support point. OPEN BOTTOM WETWELL INSTALLATION: Bottom of excavation should be corr'rpacted to 95% Standard Proctor Density. Pour reinforced concrete base one foot deep and at least two feet larger than the fiberglass wetwell outside diameter. As soon as the concrete has set-up enough to support the fiberglass wetwell , lower the wetwell into place . Pour a minimum of one foot of reinforced concrete on the inside, also a minimum of one foot deep and two feet from the fiberglass wetwell wall on the outside of the wetwell. Insert ram neck type sealant on the outside of fiberglass wetwell around the bottom where the fiberglass and concrete come together. CUTOUTS: Cutouts in wetwell wall should be made with proper cutting tools, such as jig saw or hole saw. Do not use axe or other impact-type tools . INSTALLATION OF SEWER PIPE: TYPE 1: Make the cutout in the wetwell wall, the outside diameter of pipe , plus 1/2 i nch maximum. Slip pipe into position . Apply industrial grade silicone around the pipe next to the wetwell wall cutout on the inside and on the outside . Cover the outside siliconed area with epoxy grout and backfill. TYPE 2: Make the cutout in the wetwell wall, the outside diameter of pipe , plus 1/2 inch maximum . Grind the outside surface of the pipe and both the inside and the outside surfaces of the cutout in the wetwell wall. (Apply a priming agent to any PVC pipe that might be used before fiberglass lay-up.) Insert the pipe through the cutout in the wall of the wetwell. Apply fiberglass putty to the inside and the outside of the wetwell wall cutout, filling openings between pipe and cutout. Make a good radius for the 3 S:\SpecOsk\Specifications\Wetwell Spec.rt!
