The Marke Luxury Apartments|Santa Ana, CA|3,591 GPM - 24.8' TDH

jweddell1,000gpm - 5,000gpm, 100-Year Storm, Mixed Use, Pacific, Stormwater, Stormwater Featured, Stormwater Runoff

This stormwater pump station was designed to handle variable flows of stormwater runoff. The typical stormwater expectations called for low flow pumping, but this pump station needed to handle high flows as well. Two different sizes of submersible centrifugal pumps were used; a 7.5 hp pump and a 25 hp pump. The pumps required differently sized discharge piping and valves for each pump. A PLC control panel handles all lift station functions including starting and stopping on level, SCADA options, an autodialer for communications, and a soft starter for the large pump.

Gas Refinery Process Water

Exxon Mobil|Chalmette, LA|30,000 GPM - Various TDH

jweddell10,000gpm +, Central, Stormwater, Stormwater Runoff

To address the industrial stormwater concerns of coastal Louisiana, this large, precast concrete pump station was designed to meet super-high flows of runoff at this Exxon refinery. Five vertical turbine pumps and three submersible pumps, capable of pumping 60,000 GPM, are spread across three large interconnected rectangular wet wells. This approach was much more affordable than a single poured in place sump, and the connection tubes make the functionality near identical. A robust steel baffle slows incoming stormwater at the inlet line to reduce turbulence and wear on the sump components.

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.

University of Oregon|Eugene, OR|350 GPM - 25' TDH

jweddell300gpm - 500gpm, Flood Control, Pacific, Parking Lot Drainage, Schools, Stormwater, Stormwater Runoff

This package pump station was designed to meet low flows of stormwater expected after the expansion of this university building. The duplex pump configuration with submersible centrifugal pumps provides reliable and lasting pumping capabilities. A simple UL listed control panel with an intrinsically safe (IS) barrier and basic alarm was designed and supplied as a part of the electrical layout for this package pump station. This system was designed with four floats for liquid level-sensing and automatic starting and stopping of pumps on level
