This industrial power plant needed a package lift station to meet the requirements for municipal wastewater. The 23-foot-deep sump holds duplex Goulds submersible sewage pumps specified to meet the 50 gpm maximum flow requirements. A precast concrete valve vault contains the system valves and a force main junction. Both the below-grade wet well and valve vault are pedestrian rated. Liquid level-sensing controls are a pressure transducer and floats for backup. The outdoor control panel includes a receptacle for an owner supplied onsite generator.

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.
