The Marine Corps Base Camp Pendleton needed this large wet-dry wastewater lift station to replace an existing system to allow the construction of new enlisted quarters. The new lift station included triplex dry-pit pumps to handle super-high flows of sewage from the facilities. An 8’ diameter precast concrete sump collects the sewage. Suction lines connect the sump to a 200-square-foot rectangular dry pit where the pumps, flow meter, and valve assembly are located. This lift station also includes an upstream grinder pit with a Macho Monster sewage grinder to pulverize solids into passable sizes.

Solyndra Commercial Complex

This new commercial complex required two new stormwater pump stations designed to meet low flows of runoff. The manholes and hatches were designed at grade to integrate seamlessly with the brick patio and walkway. Submersible centrifugal pumps in a duplex configuration discharge to below grade valve assemblies accessible by valves cans. The UL listed control panels are contained by stainless steel NEMA enclosures and include intrinsically safe barriers. Both lift stations were designed with the same primary components for site standardization.

This “turnkey” replacement lift station was designed, supplied, and installed to meet super-high sewage flow with infiltration and inflow requirements of a municipal wastewater lift station. Submersible solids-handling pumps in a triplex configuration were installed. The below-grade valve assembly includes plug valves, check valves, ball valves, a pumping port, and a pigging port. The UL listed control panel has an ultrasonic transducer for primary liquid level sensing, redundant float controls, and an autodialer alarm. VFDs were also included in the lift station controls.

This unique package wastewater lift station was designed to meet the high sewage flows of this US Army Corps of Engineers managed reservoir and nearby campgrounds. Vertical chopper pumps were engineered above the sump in a precast concrete structure with the above grade valve assembly. Two inlet lines were engineered with extra piping to direct influent toward the bottom of the sump. The structure also contains the UL listed control panel. Float controls were used for liquid level-sensing, and the control panel included soft starters typical for vertical shaft pumps.

Fresh & Easy Distribution Center

jweddell100gpm - 300gpm, Food & Beverage, Pacific, Wastewater

The expansion of this distribution center for Fresh and Easy food products required a package lift station designed to meet medium wastewater flow requirements. This lift station for the 88-acre storage and supply facility uses an inlet line drop bowl to protect submersible solids-handling pumps in a duplex configuration from cascading influent and turbidity. A below-grade valve vault holds all the valves assembly for two, parallel force mains. An outdoor UL listed control panel utilizes float controls for liquid level-sensing and includes an autodialer for communications.
