This municipal water district replaced an existing lift station with this packaged lift station designed for the high sewage flow requirements. 15 hp submersible sewage pumps discharges to a below grade valve assembly, which includes valves, actuators, indicators, and access ports. The outdoor control panel utilizes a pressure transducer for primary liquid level sensing and float controls for backup. The panel also includes soft starters to reduce the inrush current, which can sap the onsite generator during pump starts.

After the historic Bay Meadows racetrack closed down, a large residential development began that required this large wastewater lift station. A triplex configuration of 30 hp Flygt pumps handles the high flow rates of this system. A blower system was provided as part of the lift station odor control specified by the City. The lift station electrical controls comprised a PLC, float control level-sensors, and a backup generator. The panel includes an Arc Armor® enclosure that provides safe access to low-voltage controls and separate access for high-voltage circuits.

This was a true lift station replacement by installing a new package lift station “in the hole” of the removed wet well. Submersible pumps in a duplex configuration were included to meet the low sewage flows from the federal training facility. The system valves were installed in the discharge piping inside the wet well to reduce cost and simplify the system. An outdoor alternator panel handles the controls for this package lift station. It was designed with floats for liquid level sensing and a basic alarm.

jweddell300gpm - 500gpm, Mixed Use Development, Municipal Collection, Pacific, Sewer System Expansion, Wastewater

A new development for a commercial park needed this wastewater lift station to connect the development to the municipal sewer system. Submersible centrifugal pumps in a duplex configuration were engineered to meet the medium flow high head conditions of the force main. This system needs to pump at a predefined flow rate in order to achieve the minimum force to reach the existing municipal sewer lines. The lift station control panel is a UL listed panel with redundant float controls wired for intrinsically safe use.

The Bear River Band of Rohnerville Rancheria, a federally recognized tribe of the Mattole and Wiyot peoples, purchased this package wastewater lift station for a tribal community development. The submersible pumps are located in the bottom of a 14’ prefabricated fiberglass sump, and the below grade valve assembly is located in a 5’ deep round prefabricated fiberglass valve vault. An outdoor UL listed control panel includes floats for primary and backup level controls and an autodialer for system communications.
