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.

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.

These three package lift stations were designed to meet medium flows of industrial process water with added low flows of industrial stormwater and wastewater. Submersible centrifugal pumps in a duplex configuration were specified to meet the peak flows and water chemistry identified for each pump station. UL listed control panels with floats for liquid level-sensing and basic alarms comprise the system controls for the lift stations. These packaged lift stations were integrated into stormwater, processing, and wastewater plans for the new construction of the Colusa Generating Station.

Seal of the City of Santa Barbara

City of Santa Barbara | Santa Barbara, CA | 275 GPM - 17' TDH

The City of Santa Barbara needed this packaged pump station to manage low stormwater flows from events that occur during the dry season. Duplex submersible pumps capable of passing a 3-inch solid pump the water into an existing sanitary sewer pressure main and on to treatment. This pump station includes an in-ground valve vault with plug and check valves and stainless steel discharge piping to handle oily or contaminated water conditions. Romtec Utilities supplied the complete electrical controls with liquid level sensing, alarm notifications, pump start and stop cycles, above-grade disconnect stand, and intrinsically safe circuits.

Fresh & Easy Distribution Center

Fresh & Easy Distribution Center|Riverside, CA|170 GPM - 60' TDH

jweddell100gpm - 300gpm, Food & Beverage, Pacific, Wastewater

The expansion of this distribution center for Fresh and Easy food products required a package lift station designed to meet medium wastewater flow requirements. This lift station for the 88-acre storage and supply facility uses an inlet line drop bowl to protect submersible solids-handling pumps in a duplex configuration from cascading influent and turbidity. A below-grade valve vault holds all the valves assembly for two, parallel force mains. An outdoor UL listed control panel utilizes float controls for liquid level-sensing and includes an autodialer for communications.
