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.

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.

San Andreas Sanitary District California

San Andreas Sanitary District | San Andreas, CA | 75 GPM - 28' TDH

jweddell50gpm - 100gpm, Pacific, Schools, Wastewater

A new school needed this package lift station to pump stored wastewater every 24 hours. The sump was oversized by design to hold in excess of 5,000 gallons of sewage that would be pumped out at specified medium pumping rate to a low-level shutoff float control. The submersible solids handling pumps in a duplex configuration are accessible by a crane installed on the top slab. An outdoor UL listed control panel is tied-in to an onsite generator for backup power and utilizes an autodialer for communications.
