Industrial Stormwater Pump Station

British Petroleum Refinery|Bellevue, WA|350 GPM - 30' TDH

jweddell300gpm - 500gpm, Industrial, Industrial Process Water featured, Oil & Gas, Oil/Water Separators, Pacific, Stormwater, Stormwater Runoff

This package lift station handles the medium flows of stormwater and process water drainage at this oil refinery. A stormwater plan is required at most industrial facilities and BP proactively chose a reliable lift station to manage its environmental footprint. Duplex submersible centrifugal pumps and a below grade valve assembly comprise the major underground components of this system. An outdoor control panel utilizes float controls and an ultrasonic transducer for primary and backup liquid level-sensing.

Utica East Ohio Midstream needed two new pump stations to handle low flows of stormwater runoff at its new Kensington Plant in Ohio. To responsibly contain potentially hazardous stormwater from the topsoil, these pump stations were designed with double-wall fiberglass wet wells with interstitial leak detection. Both pumping systems included corrosion resistant components and sensors due to the potential presences of LNGs in the stormwater runoff. Pumps were engineered with 7.5 hp Ebara pumps in a duplex configuration, and different impellers were specified for each of the two pump stations meet slightly differing head requirements.

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.

An IMTT industrial storage facility needed this stormwater pump station to collect runoff and pump it to treatment onsite. The duplex submersible pumps were engineered to handle the expected medium flows of stormwater. The pumps also needed to handle water that could potentially carry oil or other industrial chemicals stored on the site. An above-grade valve assembly used ball valves and check valves that were vertically integrated for easy access. The pump station electrical controls were located on an existing wall in the water treatment area.
