A.2 MATERIALS: POLYESTER RESINS AND FIBERGLASS WOVING The resin system shall be designed for atmospheres containing sulfuric acid, gases and liquids associated with wastewater collection systems. The resulting reinforced plastic material must meet the requirements of A.S.T.M. D 3753 specification and be suitable for the harsh wastewater environment. The exterior surface shall have a gray UV inhibitor resin coating-minimum of.125-inch thickness. A.3 MONOLITHIC FABRICATION AND PHYSICAL REQUIREMENTS: A.S.T.M. D3753 (SEC6) The internal surface shall be smooth to prevent grease and scum from attaching to the walls. The use of corrugated material is not allowed. The bottom and any reinforcement necessary are to be completely enclosed with fiberglass lay up. Pump stub outs, electrical, service inlets and discharge lines shall be factory installed per A.S.T.M. D3299. Field inlets shall be installed by approved methods and with materials furnished by Technical Sales Corporation.

Hatch door shall have automatic hold open S/S safety arm and tamper proof S/S hinges. The aluminum top cover shall be through bolted to the top flange to form a robust lid capable of withstanding occasional wheel loads. Wet well tops shall be all aluminum. If a concrete slab-is to be installed, the fiberglass top shall include a neck extension for the aluminum hatch for the full thickness of the slab. The use of a concrete top piece, where concrete is exposed to the sewer gases, is not permitted. A.5 FIELD PENETRATIONS AND INLET HUBS: use only the epoxy kits furnished by TSC Field penetrations for inlet hubs and cutouts can be made with a hole or jigsaw and shall be sealed with waterproof epoxy kits furnished by Technical Sales Corporation. Wet well inlets or"hubs" can be field fabricated with short pieces of PVC pipe, pipe coupling or a bell end of gasket joint PVC pipe. Turn the gasket joint"up stream" to make it a flexible connection. Cut a reasonable round hole, insert pipe into wet well, and "mud and wipe"the joint- both inside & outside with the epoxy that is furnished. Material will set up in 15 minutes and form a watertight seal equal in strength to the wet well and influent pipe. Epoxy kits allow all inlets to be field fabricated and installed for the specific job conditions. F/FS/TSCV/LF/Wetwell 48-60-72 Pg 1 of 2,Rev 2005
