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.

The Union Pacific Depot in Cheyenne, Wyoming needed two new stormwater pump stations to replace existing systems. The first station used Ebara 25 hp submersible pumps in a triplex configuration to handle stormwater runoff from a parking lot and additional drains. The second station used Ebara 7.5 hp submersible pumps in a duplex configuration to pump stormwater that drains from the pit of a railway turntable. Both systems include precast concrete valve vaults. Each vault was preassembled with Val-Matic Cam-Centric® plug valves, Val-Matic Swing-Flex® check valves, and Ashcroft pressure gauges. Both stormwater systems discharge into an evaporation pond that was installed as a part of this larger water collection replacement, which also included three additional Romtec Utilities wastewater lift stations.

The City of Brawley needed this packaged lift station to handle high flows of wastewater at its municipal treatment plant. 12 HP submersible pumps in a duplex configuration were used to meet the high flow pumping needs and a conductive probe was used for liquid level-sensing. The in-ground valve assembly and meter assembly were each located in separate vault structures for a cost effective design and easy access. An outdoor, UL listed control panel was protected from weather and sunlight by a six-post shelter, which also covers the sump entry hatch and electric disconnect panel.

The Marine Corps Base Camp Pendleton needed this large wet-dry wastewater lift station to replace an existing system to allow the construction of new enlisted quarters. The new lift station included triplex dry-pit pumps to handle super-high flows of sewage from the facilities. An 8’ diameter precast concrete sump collects the sewage. Suction lines connect the sump to a 200-square-foot rectangular dry pit where the pumps, flow meter, and valve assembly are located. This lift station also includes an upstream grinder pit with a Macho Monster sewage grinder to pulverize solids into passable sizes.

This unique package wastewater lift station was designed to meet the high sewage flows of this US Army Corps of Engineers managed reservoir and nearby campgrounds. Vertical chopper pumps were engineered above the sump in a precast concrete structure with the above grade valve assembly. Two inlet lines were engineered with extra piping to direct influent toward the bottom of the sump. The structure also contains the UL listed control panel. Float controls were used for liquid level-sensing, and the control panel included soft starters typical for vertical shaft pumps.
