This municipal lift station in the Napa Valley was designed to handle medium sewage flows and medium head conditions. Flygt sewer pumps were supplied in a duplex configuration to integrate with the Tops Basin and discharge elbows. The complete structural components of this lift station were designed to finish two feet above-grade to be above the flood plain for the area. A proprietary control device and pressure transducer provide the system electrical controls.
This package lift station was designed to meet the medium wastewater flows of this California prison. Solids-handling pumps in a duplex configuration are protected from cascading influent by a drop bowl. The liquid level-sensing is controlled by a pressure transducer and a float in used for emergency backup. A below-grade valve assembly holds the system’s valves, flow meters, and pressure gauges. An outdoor PLC panel with a basic alarm and an added input for a radio modem comprise the systems controls.
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.
In order to expand the municipal sewer system, this lift station was configured to pump to an existing gravity line flowing to treatment. A 24-foot-deep by 10-foot-diameter wet well collects the sewage flows. The wastewater is pumped at 120 gpm 10,000 lineal feet of 10” force main against 206’ TDH with 23 hp high head submersible solids handling pumps. A sheltered control panel utilizes an intrinsically safe barrier for in-well electrical, such as the pressure transducer and conductive probe for primary and backup level controls.
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.
