jweddell50gpm - 100gpm, Mountain, Municipal Collection, Sewer System Expansion, Wastewater

An expanding sewer system for annexed land required this packaged wastewater lift station. Duplex submersible solids handling pumps are designed to meet the medium flow requirements and pass solids up to a 2” diameter. To save space, the system valves are integrated into the discharge piping in the sump. An outdoor control panel utilizes floats for liquid level-sensing and an intrinsically safe barrier for in-well electrical components. The electrical controls are wall mounted.

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.

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.

A large residential development required this package lift station to meet the high sewage flows for over 330 residential lots. Two inlet lines are fitted with deflector panels to reduce the in-well turbidity and protect the duplex submersible solids handling pumps from cascading influent. A below-grade valve vault contains the system valves, access ports, and pressure gauges. A sheltered, outdoor control panel utilizes a pressure transducer and backup conductive probe for liquid level-sensing and is connected to an emergency backup generator.

Four identical lift stations were supplied to address sewage and cooling process wastewater from this commercial facility. This was the final of four lift stations supplied to Microsoft’s 70-acre data center. Aircraft rated hatches are included for each lift station to handle heavy forklift traffic. Ebara submersible sewer pumps handle the medium flow and average head condition of the system. An outdoor UL listed control panel utilizes an intrinsically safe barrier for in-well electrical controls and utilizes float controls for liquid level-sensing.
