A pumping station enclosure building 3.5m by 4.5m located at the site of Well #1 housing treatment and control facilities Piping and appurtenances to connect Well # 2 to the main discharge header. Two sodium hypochlorite feed pumps rated at 0.8 L/hr complete with auto switchover controls, piping, valves, and associated monitoring equipment. One sodium hypochlorite solution tank complete with spill containment. One back flow preventer on the in-plant water supply line, a flow control valve rated at 8.5 L/s on the discharge header, and a screened well vent for Well #1. One water level pressure transducer in Well # 1 and Well #2. 75 mm diameter header piping in the pumphouse. Ten hydropneumatic Pressure Vessels with 450 L usable volume. Three Flow Metering Devices measuring accumulative daily well pump discharge flows, one in each well discharge to measure the raw water flow, and one in the pumphouse discharge to measure the treated flow. Approximately 13 m of 600 mm diameter watermain on the existing site for additional chlorine contact time. A chlorine residual analyzer following the contact main. 150 mm diameter and 120 m long watermain extending between the pumping station enclosure building and the first consumer connection. Two cartridge filter trains, one duty and one standby for the removal of particles 5 micron and larger, rated at 8.5 L/s A turbidimeter for monitoring purposes only. Maximum Water Taking m3/day 2
