The expansion of the Exelon Medway Generating Station required four unique pump stations to support future operations.
Lakehurst Naval Air Station|Trenton, NJ|250 GPM - 24.77' TDH
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.
Valley Fine Food Processing|Benicia, CA|45 GPM - 35' TDH
This food processing plant in Benicia, California needed a wastewater lift station to handle combined sewage and process water from the production of pasta. The lift station design included Tsurumi grinder pumps in a duplex configuration. These submersible grinder pumps were included to handle pasta and cheese that occasionally get into the process water. The system electrical controls comprise a standard UL listed panel with float controls for liquid level sensing. The lift station pumps into an existing sewer main and on to treatment.
Santa Barbara Cottage Hospital|Santa Barbara, CA|1,095 - 21.5' TDH
This simple package lift station was designed to handle the medium flows of stormwater at this hospital facility. Submersible centrifugal pumps in a duplex configuration alternate pump starts or can both operate in high stormwater events. The pumps are protected from inflows by an HDPE deflector panel. There is a below-grade electrical junction box in a concrete vault. System controls were designed with a UL listed control panel, float controls for liquid level-sensing, a basic alarm, and an autodialer for telecommunications.
Chino Men's Prison|Chino, CA|135 GPM - 30' TDH
This package lift station was designed to meet the medium wastewater flows of this California prison. Solids-handling pumps in a duplex configuration are protected from cascading influent by a drop bowl. The liquid level-sensing is controlled by a pressure transducer and a float in used for emergency backup. A below-grade valve assembly holds the system’s valves, flow meters, and pressure gauges. An outdoor PLC panel with a basic alarm and an added input for a radio modem comprise the systems controls.
