Valley Fine Foods

Valley Fine Food Processing|Benicia, CA|45 GPM - 35' TDH

jweddell5gpm - 50gpm, Food & Beverage, Pacific, Wastewater

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

jweddell1,000gpm - 5,000gpm, Hospitals, Pacific, Stormwater, Stormwater Runoff

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

jweddell100gpm - 300gpm, Corrosive/ Caustic Pumping, Meter Vaults, Pacific, Prisons/Detention Centers, Valve Vaults, Wastewater

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.

City of Shafter in California

The City of Shafter|Shafter, CA|400 GPM - 28.5' TDH

jweddell300gpm - 500gpm, Pacific, Replacements & Retrofits, Wastewater

A suburb of the City of Shafter required a lift station package to repair and rehabilitate an existing wastewater sump. Duplex submersible centrifugal pumps and discharge pipe mounting brackets were fitted to a concrete slab poured in the bottom of the existing manhole. The Romtec Utilities package included the proper components to operate in this 26-foot-deep sump. An outdoor MultiSmart control panel utilizes conductive probes for primary and backup level controls and an autodialer for communications. This retrofit package saved about 60% the cost of a new lift station.

jweddell100gpm - 300gpm, Equipment Washdown, HRSG Blowdown, HRSG Pumping, Industrial, Industrial Process Water featured, Industrial Water, Pacific, Power Generation, Stormwater, Wastewater

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.
