Gasket: Before lid is bolted on by the manufacture/ or vendor, the upper flange is fitted with a self-adhesive EPDM gasket to prevent water and sand intrusion. i. Label: Each tank shall be clearly marked with the manufacture or supplier name and the month and year of the manufacture. V. EFFLUENT PUMP (Exhibit 2) a. Product Specifications: Champion model pump CPWH5-13 Pump is required that all STEP pumps with the system have similar performance curves. The system was designed with the following performance criteria. The supplier shall provide a pump that closely meets the performance specification described below. The utility shall make final determination of product acceptance. All pumps shall be 115v and have 30-foot minimum cord length. Construction Materials Type: Sewage Ejector Submersible Pump with a Vortex Impeller Motor housing: Cast iron Shaft: Stainless Steel Mechanical Seals: Carbon and Ceramic Impeller: Cast Iron, Engineered Thermoplastic or AISI Bottom Plate: Cast Iron Volute: Cast Iron Hardware: AIS 300 Series Stainless Steel Support Legs: Three integral Feet or base Technical Data Flow Range: 70 gpm Temperature Range: 32F - 120F Continuous Solid Size: Up to 3/4 inch Phase-Volt-Cycles: 1-115-60hz Lubrication: Oil Wear Plate: Reversible Power Cord: 30 Minimum HP: 1/2 Pump Discharge: 2-inch Head Shut-off: 35 b. Effluent Sewage Ejector Vortex (SEV) pump motor starters and capacitors shall be in the motor or adjacent housing. Either a control box housing or a junction box is required to connect the pump and level controls to the service user power source. VI. CHECK VALVE a. The check valves shall be swing check with valve bodies constructed of PVC SCH40, heavy-duty 125 psi WOG. VII. HOSE CONNECTION a. A ball valve will be installed to the internal discharge piping with a union valve, a 6 piece of Flex (PVC Sch 40) attached to a TEE on the riser of the pump. The riser is made up of 1.5 Sch 40 PVC with a plastic check valve below the TEE, and a 10 pipe, on the top side of the TEE, to a 90 degree PVC coupling with a check valve. b. Detail LPS-02 shows the construction detail for STEP Basin. VIII. LEVEL CONTROLS SWITCHES (Exhibit 3) a. Float Switch Conery 2900-B1S4-30 Blue floats shall be utilized for level control switches. Float Switch shall be encased within a polyurethane ball. In the simplex system, two separate switched are required with each switch designated to either turn the pump off and on or activate a high-water level alarm. A differential mercury switch may be used which has combined the on and off function within the mercury control. A mechanical secondary switch is still required to activate the high-water alarm. IX.

Wiring to connect the pump to the power source shall be suitable for the direct burial and comply with State and local codes, wiring for the level sensors and control panel must also comply with these requirements. c. A high-water alarm bell/ buzzer and light shall be utilized with Low Pressure Sewer System. The alarm shall be assigned so that the service user can reset the audio alarm after a malfunction, but not disable it for future malfunctions. The alarm system shall be mounted outside the service location. d. All wires shall be neat, color coded, 14GA, TEW, rated for 105. e. An electrical schematic shall be mounted permanently in the control box. f. Detail LPS-07 shows the construction detail for Control Panel. X. SERVICE LINE a. The service line connecting the pump chamber to the main shall be a minimum of 1 1/2 inch diameter. Installation shall generally comply with the specifications governing the installation of mains. b. Internal discharge piping shall be PVC schedule 40. The standard size of the internal piping shall be 1 1/2 -inch diameter and shall include a PVC ball valve inside the pump chamber at top of discharge leg. XI.

Inspections may be made by Utility personnel in manufacturer's or supplier's yard, within the plant, upon delivery and again after installation. The wall thickness shall be at least .025 inches. When less than a minimum 0.25-inch thickness or any delamination is suspected within a portion of the tank, Utility personnel may drill a 1/8-inch diameter hole through the tank wall for inspection purposes. At any time, if the required minimum 0.25-inch thickness id not found, repair (if Feasible) shall be the responsibility of the contractor or supplier. If repair is judged unfeasible, the tank shall be rejected. A percentage of delivered tanks shall be tested at the delivery site by the supplier as directed by the Utility. If 20% or more of the tanks are rejected for any of the reasons (pressure and material), each tank under the contract will become suspected of substandard quality and may be rejected by the Utility. If failures become commonplace, the Utility may, at its discretion cancel the supply contract at any time with written notice and will take effect upon receipt of said notice. XII.
