Document Description
Improvements at the Water Treatment Plant (WTP) site include constructing a new ~6,800 square-foot water treatment building, 600,000-gallon potable clearwell tank, 110,000-gallon backwash storage tank, backwash water recycle pump station, leach field and septic tank, and a potassium permanganate dosing station. Aggregate base would be installed throughout the WTP site to provide access to the new and the existing facilities, and a small parking area would be installed adjacent to the new water treatment building. Miscellaneous drainage improvements would be completed throughout the WTP site. Power poles, overhead electrical lines, a ground-mounted transformer, a Supervisory Control and Data Acquisition (SCADA) control system, ~3,415 feet of pipeline, and a new 400 kW emergency back-up generator would be installed at the WTP site, and modifications would be made to the regulation reservoir and existing 500,000-gallon water storage tank. SCADA equipment would be installed at the Ewing Pump Station; improvements would include either constructing a ~30-foot communications tower adjacent to the Pump Station building or mounting a ~30-foot-tall antenna to the building.
