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.

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.

Oak Springs Ranch | Wildomar, CA | 262 GPM - 53.9' TDH

jweddell100gpm - 300gpm, Apartment Complexes, Pacific, Residential Development, Wastewater

This packaged lift station was designed to meet the medium flows of sewage from an upscale apartment development. The concrete wet well was precast with Ameron T-Lock lining to protect the concrete from hydrogen-sulfide off-gassing. Ebara submersible sewage pumps in a duplex configuration provide redundant pumping capabilities suitable for the medium head conditions. This lift station also includes a bioxide odor control system in the design. A UL listed control panel provides the complete electrical controls with an autodialer for communications.
