This City of Guadalupe, California needed a new wastewater lift station to accommodate a residential development for up to 800 homes.
Shea Center | Huntington Beach, CA | 1800 GPM - 28.19' TDH
A new 144,000 square feet, two building industrial center needed a large stormwater pump station to handle the runoff from the site. This triplex system includes a fourth, “jockey” pump to handle low flow dry-season runoff. The three large pumps are 20 hp Ebara submersible pumps designed for redundant pumping during high flow events. A pressure transducer serves as the primary level-sensing device and operates inside of a perforated stilling well designed to prevent solids from interfering with the sensor. The electrical controls are configured with a logic relay, intrinsically safe circuits, and communications.
Bay Meadows | San Mateo, CA | 1218 GPM - 96' TDH
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.
City of Port Orchard|Port Orchard, WA|200 GPM - 64' TDH
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.
Pacific Convenience & Fuels|Shingle Springs, CA|15 GPM - ' TDH
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.
