These three package lift stations were designed to meet medium flows of industrial process water with added low flows of industrial stormwater and wastewater. Submersible centrifugal pumps in a duplex configuration were specified to meet the peak flows and water chemistry identified for each pump station. UL listed control panels with floats for liquid level-sensing and basic alarms comprise the system controls for the lift stations. These packaged lift stations were integrated into stormwater, processing, and wastewater plans for the new construction of the Colusa Generating Station.

The City of Santa Barbara needed this packaged pump station to manage low stormwater flows from events that occur during the dry season. Duplex submersible pumps capable of passing a 3-inch solid pump the water into an existing sanitary sewer pressure main and on to treatment. This pump station includes an in-ground valve vault with plug and check valves and stainless steel discharge piping to handle oily or contaminated water conditions. Romtec Utilities supplied the complete electrical controls with liquid level sensing, alarm notifications, pump start and stop cycles, above-grade disconnect stand, and intrinsically safe circuits.

Fresh & Easy Distribution Center

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.

The newly constructed headquarters for the Sacramento Municipal Utility District purchased this package lift station to meet its medium sewage flow requirements. Submersible solids-handling pumps in a duplex configuration were specified in a deep well because this facility represents one of the ten largest public utilities in the country.
