jweddell1,000gpm - 5,000gpm, 100-Year Storm, First Flush, Mixed Use Development, Pacific, Stormwater, Stormwater Collection, Stormwater Runoff

A new 144,000 square feet, two building industrial center needed a large stormwater pump station to handle the runoff from the site. This triplex system includes a fourth, “jockey” pump to handle low flow dry-season runoff. The three large pumps are 20 hp Ebara submersible pumps designed for redundant pumping during high flow events. A pressure transducer serves as the primary level-sensing device and operates inside of a perforated stilling well designed to prevent solids from interfering with the sensor. The electrical controls are configured with a logic relay, intrinsically safe circuits, and communications.

Plantation Pipe Line Received a Stormwater Pump Station

Plantation Pipe Line|Polk County, GA|175 GPM - 90' TDH

jweddell100gpm - 300gpm, Eastern, Oil & Gas, Stormwater, Stormwater Runoff

This package stormwater lift station was configured to meet the medium runoff flow of this industrial property. One submersible centrifugal pump makes this a simplex station with an in-well check valve. The single pump handles high head conditions caused by 9,000 feet of 4” force main. Additional system valves are located in a below grade valve vault. An outdoor control panel includes floats for liquid level-sensing and a basic alarm for communication. A Thern crane was included with this station to raise and lower the pump.

Home Depot|Perris, CA|900 GPM - 16' TDH

jweddell500gpm - 1,000gpm, Detention Pond Pumping, Detention Ponds, Pacific, Parking Lot Drainage, Stormwater, Stormwater Runoff, Warehouse/Fulfillment Centers

The construction of a new Home Depot required a large detention pond and a new pump station to handle stormwater from the commercial development. This economical pump station uses 7.5hp Ebara pumps in a duplex configuration to meet the required flow rates to empty the detention pond. Parallel force mains were included with valve cans to provide simple and inexpensive piping and control valves. This submersible system uses cost-effective precast concrete barrels and a monolithic base to construct strong and reliable sump.

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.

Pacific Gas and Electric Company

PG&E Power Plant|Colusa, CA|300 GPM - 23' TDH

jweddell300gpm - 500gpm, Equipment Washdown, Industrial, Industrial Water, Pacific, Power Generation, Stormwater, Stormwater Runoff, 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.
