Two skid-mounted lift station systems retrofitted two existing stations for medium sewage flows at this federal correctional facility. Preassembled above-grade skids with Pioneer self-priming pumps in duplex configurations drop suction piping into the existing sumps to pump effluent to the existing force mains.
These package lift stations were designed to meet the high head pumping requirements for this training facility of the US Army Corps of Engineers. For one station with over 7,000 ft. of 8” force main, 35 hp duplex submersible centrifugal pumps were supplied to achieve the 300 gpm flow rate . The second lift station used smaller, 4 hp duplex grinder pumps to meet its pumping requirements. Outdoor UL listed control panels utilize float controls for level-sensing and soft starters to provide advanced pump diagnostics and to reduce inrush currents. Autodialers were specified for communications.
This project was initially recognized as a rehabilitation project but Romtec Utilities and David Evans and Associates, Inc. determined that they needed a replacement lift station to meet their increased stormwater demands.
