jweddell1,000gpm - 5,000gpm, Municipal Collection, Pacific, Sewer System Expansion, Wastewater

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.

Holt Homes | Camas, WA | 415 GPM - 117' TDH

jweddell300gpm - 500gpm, Municipal Collection, Pacific, Residential Development, Sewer System Expansion, Urban Growth, Wastewater

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.

This large commercial facility needed identical lift stations to manage wastewater in the form of sanitary sewer and discharge water from the cooling processes. This was the second of four Romtec Utilities lift stations supplied to Microsoft’s 70-acre data center. Aircraft rated hatches are included for each lift station to handle heavy forklift traffic. Outside the sump, two valve cans provide access to the below-grade check valves. An outdoor UL listed control panel utilizes an intrinsically safe barrier for in-well electrical controls and utilizes float controls for liquid level-sensing.

This package lift station was configured to meet the medium sewage flow requirements of a commercial wastewater system. This was the first 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. Outside the sump, two valve cans provide access to the below-grade check valves.
