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 City of Clovis | Clovis, NM | 100 GPM - 15.4' TDH

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.

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.

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.

Geothermal Power Facility in Nicaragua

A commercially owned geothermal power facility in Nicaragua purchased this package lift station to meet its medium wastewater flows. Shipping the major components for this system required precise documentation and plans. Duplex submersible chopper pumps, in-well check valves, and plug valves with valve cans are some of the major below grade components of this system. The outdoor UL listed control panel utilizes floats for liquid level-sensing and includes an autodialer for communication. The complete Romtec Utilities package system was owner-installed as part of its phase I development.
