The expansion of a college campus required this stormwater pump station to handle medium flows of stormwater runoff. To meet the required pumping rate, 7.5 hp Ebara submersible centrifugal pumps were designed in a duplex configuration. This pumping system was designed with dual force mains and check valves integrated in the discharge piping to simplify the engineering for the system. Romtec Utilities provided the complete electrical engineering plans for the UL listed control panel. Floats for primary and backup liquid level-sensing were supplied to give the system added redundancy.

The US Army Corps of Engineers worked with Romtec Utilities to design this lift station to replace an existing septic system. The resulting package wastewater lift station met the high sewage flows of this publicly owned industrial complex. The submersible sewage pumps in a duplex configuration are explosion proof to meet the wet well space classification. An outdoor UL listed panel utilizes floats and a pressure transducer for intrinsically safe level controls. It also includes an autodialer for communications and a blower for odor control.

jweddell50gpm - 100gpm, Mountain, Municipal Collection, Sewer System Expansion, Wastewater

An expanding sewer system for annexed land required this packaged wastewater lift station. Duplex submersible solids handling pumps are designed to meet the medium flow requirements and pass solids up to a 2” diameter. To save space, the system valves are integrated into the discharge piping in the sump. An outdoor control panel utilizes floats for liquid level-sensing and an intrinsically safe barrier for in-well electrical components. The electrical controls are wall mounted.

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.

Fresh & Easy Distribution Center

jweddell100gpm - 300gpm, Food & Beverage, Pacific, Wastewater

The expansion of this distribution center for Fresh and Easy food products required a package lift station designed to meet medium wastewater flow requirements. This lift station for the 88-acre storage and supply facility uses an inlet line drop bowl to protect submersible solids-handling pumps in a duplex configuration from cascading influent and turbidity. A below-grade valve vault holds all the valves assembly for two, parallel force mains. An outdoor UL listed control panel utilizes float controls for liquid level-sensing and includes an autodialer for communications.
