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.

City of Battle Ground, Washington - Triplex Lift Station Design Project Assets DRAWINGS SITE-PLANS DESIGN PANEL DESIGN Project Description This stormwater lift station was designed for the City of Battle Ground to support the “now and future” needs of a developing area. This was achieved by designing the system to operate with large submersible pumps in a triplex configuration to meet the expected “future” flow rates. To meet the current flow rates, the City only ...

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.

Tesoro Oil and Water Separator Pump

A remote Tesoro Corporation industrial site needed this stormwater pump station to handle water discharged from an oil/water separator which processes on-site runoff. Submersible centrifugal pumps were used in a duplex configuration in this shallow wet well. The 7.5 hp Ebara explosion-proof pumps were sized to meet low flow, medium head conditions for stormwater. Check valves and plug valves were integrated into the discharge piping in the well for a simple and cost-effective design. The precast concrete wet well and the access hatch are both pedestrian rated.
