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.
Exxon Mobil|Chalmette, LA|30,000 GPM - Various TDH
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.
British Petroleum Refinery|Bellevue, WA|350 GPM - 30' TDH
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.
Dow Chemical Company|Plaquemine, LA|8,500 GPM - 32' TDH
This package pump station was designed to respect the confidentiality of this industrial facility. The entire system was delivered with much of the hardware preinstalled in the fiberglass wet well to facilitate simple, “drop-in” installation.
Orange County, California|Anaheim, CA|4,500 GPM - 32.5' TDH
To create new potable water, this lift station pumps clean stormwater from a collection/storage basin to a treatment facility. Duplex vertical turbine pumps move high flows of water very efficiently and use soft starters to reduce torque on the vertical shaft and provide additional pump diagnostics. Also included is an above-grade valve assembly on the top slab. The control panel utilizes an ultrasonic transducer for primary level controls and a pressure transducer for backup. The entire package lift station is located inside an owner-supplied control building.
