City of Battle Ground, Washington - Triplex Lift Station Design Project Assets DRAWINGS SITE-PLANS DESIGN PANEL DESIGN Project Description This stormwater lift station was designed for the City of Battle Ground to support the “now and future” needs of a developing area. This was achieved by designing the system to operate with large submersible pumps in a triplex configuration to meet the expected “future” flow rates. To meet the current flow rates, the City only ...
St. Helena Napa Valley's Main Street

The City of St. Helena|St. Helena, CA|254 GPM - 49.5' TDH

jweddell100gpm - 300gpm, Municipal Collection, Pacific, Sewer System Expansion, Wastewater

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 medium flow sewage lift station was designed for a new development to meet the Sammamish Plateau Water and Sewer District lift station design standards. These standards specify a PLC controller with touchscreen HMI, SCADA options, a precast concrete valve vault, wet well, meter vault, and duplex submersible pumps. In addition to these design standards, this lift station needed to tie-in to an existing force main owned by the District. Romtec Utilities provided the tie-in force main designs and calculations as well as VFDs (variable frequency drives) to match the changing flow and pressure conditions of the existing force main.

The renovation of the University of Washington’s Husky Stadium required a new lift station to handle medium flows of wastewater. Robust, 10hp Vaughan Chopper pumps were used in a duplex configuration to macerate solids and to pump under unpredictable conditions. The lift station, valve vault, and the access hatches were designed as traffic rated to accommodate loading/unloading next to the main grandstand. The UL listed control panel starts, stops, and alternates each pump cycle at levels measured by Noltaniva float sensors.

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.
