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 package lift station was configured to handle low flows of industrial process water used for nuclear power generation. This lift station was one of the earliest systems to be installed during the construction of two new reactors at the plant. Submersible grinder pumps in a duplex configuration and a below grade valve assembly comprise the principal mechanical operations of the station. An outdoor control panel utilizes floats for primary liquid level-sensing, and an autodialer for communications and alarm notification.
Duke Energy replaced the Dan River Steam Station with a new gas fired power plant and needed a new pump station to handle medium flows of blow down water from the heat recovery steam generator.
