This wastewater lift station was designed to meet the standards of the Lakehurst Naval Air Station while remaining cost effective. A duplex pump configuration utilized submersible 7.5 HP Weil Slicer Pumps to handle suspended solids in the sewage. A UL listed control panel was designed and manufactured in a NEMA 4 enclosure for outdoor operation. Nolta floats were used for the in-well liquid level sensing. The below-grade structural components were designed and supplied precast concrete vaults painted with a marine epoxy exterior coating to prevent moisture incursion.

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.

The McCormick Woods northern development purchased this lift station configured to meet the medium flow requirements for municipal sewage. This package lift station was needed because of the uneven terrain surrounding the development. Two submersible solids handling pumps pump to a below-grade valve assembly containing the lift station valves and access ports. A sheltered PLC control panel utilizes a pressure transducer for primary liquid level-sensing with backup float controls. The panel is tied to an onsite generator for emergency backup power.

The construction of a new gas station and convenience store required this low flow sewage lift station. Goulds submersible grinder pumps in a duplex configuration are designed to macerate and pump wastewater that contains solids or fabric materials without becoming clogged. The complete valve assembly is vertically oriented and contained within the wet well discharge piping. An outdoor UL listed control panel contains an intrinsically safe barrier for in-well electrical, floats for level-sensing controls, and a NEMA 4X stainless steel enclosure.
