When a public high school decommissioned an existing septic system, a replacement package lift station was needed to handle the sewage from the campus. Tsurumi submersible cutter pumps were used to pass most solids and cut larger solids into passable sizes (about 1¼” diameter). The pumps also meet the low flow low head requirements for the new 3” PVC force main. The manhole and below grade valve vault are traffic rated. The outdoor control panel was mounted on the existing support structure for the decommissioned septic.

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.

This package pump station was designed to meet low flows of stormwater expected after the expansion of this university building. The duplex pump configuration with submersible centrifugal pumps provides reliable and lasting pumping capabilities. A simple UL listed control panel with an intrinsically safe (IS) barrier and basic alarm was designed and supplied as a part of the electrical layout for this package pump station. This system was designed with four floats for liquid level-sensing and automatic starting and stopping of pumps on level
