A publicly funded greenway project required two package lift stations that were configured to meet the low flow, high head requirements for this park. Grinder pumps in duplex configurations will alternate between starts to reduce wear on the pumps and make time of operation equal.
The Groton Generating Station needed this package lift station to pump clean water as a part of its power generating processes from natural gas. The submersible centrifugal pumps in a duplex configuration meet the pumping requirements for this facility and discharge the water to parallel force mains.
This package lift station was designed to meet municipal standards for medium sewage flows at this new commercial complex. The duplex pump configuration and solids-handling pumps provide suitable preventative measures for a reliable and long-term wastewater lift station. The below-grade valve assembly included swing check valves, a pigging port, and flow meters. An on-site permanent generator and sheltered outdoor PLC control panel provide robust and programmable lift station controls. An ultrasonic transducer and a two float backup comprise the liquid level sensing controls.
This package lift station in Fort Lewis was configured to meet the medium flow requirements for a federal industrial process system with stormwater to treatment. Submersible centrifugal pumps are protected from turbulence by a drop bowl. A below-grade concrete electrical vault holds the disconnect panel and electrical connections. A drain-pipe allows this vault to double as a stormwater drain for the area around the lift station. An outdoor UL listed control panel includes a basic alarm, floats for liquid level-sensing, and a NEMA rated enclosure.
This package pump station was designed to meet a low flow of industrial process water with added low flows of industrial stormwater. The dual purposes of this pump station required shaft-driven centrifugal pumps with the motors located above-grade.
