| The Edgewater Alan R. Thomas Water Treatment Plant, PWS#3640331 is a 5.0 MGD enhanced lime softening water treatment plant. The water treatment plant currently processes approximately 2.0 MGD of potable water. Groundwater is pumped from wells to an aerator, and then flows to reactor basins where the water is softened. Polymer and lime slurry water are added to the reactor basin. Softened water flows from the reactor basins to a recarbonation basin where carbon dioxiode is added to lower the pH. Water flows from the recarbonation basin to a mixed media filter, and then to a clearwell and/or a ground storage tank. Chlorine and ammonia are added prior to the mixed media filter. Treated water is pumped from the clearwell to the distribution system. The project included construction of a 40’ diameter lime sludge thickener, a sludge pump station and truck loading station. Additional improvements include the conversion of the disinfection system from chlorine gas to liquid sodium hypochlorite, including control and monitoring systems. All steel doors were replaced with corrosion resistant F.R.P. doors.
