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.

A liquid hydrogen plant required this large 20’ deep lift station to handle super-high flows of industrial wastewater. In order to provide redundancy and expanded pumping capabilities, triplex submersible centrifugal pumps were specified in the 8’ diameter sump. A large custom valve vault holds the complete 8” valve configurations with triplex discharge piping and force main headers. Two below grade junction boxes hold electrical disconnects to comply with the classified space. An outdoor UL listed control panel uses float controls for primary and backup liquid level-sensing.

This replacement wastewater lift station was designed to meet the medium sewage flow requirements of this federal training facility. Submersible solids-handling pumps in a duplex configuration pumps the effluent through in-well valves and out a three-inch force main. An outdoor alternator panel handles the controls for this package lift station. It was designed with floats for liquid level sensing and a basic alarm. The wet well is accessible with a traffic-rated hatch.

This package wastewater lift station handles sewage flows from this large residential development neighborhood. Duplex submersible solids handling pumps pump a high flow rate from this 30’ deep wet well. The wet well includes an interior fiberglass lining and exterior coating. A below grade valve vault provides easy access to the valves, ports, and gauges. For level controls, the outdoor control panel includes a pressure transducer and floats for backup. An autodialer and backup generator are also included in the panel design and supply.

To extend the sewer system for Crescent City in Del Norte County, this sewage lift station was added to a new gravity line and force main. Duplex submersible chopper pumps pump the sewage to an existing gravity line and on to treatment. An easy-to-access below grade valve assembly contains the check and plug valves. An outdoor PLC panel is connected to a customer-supplied generator and is also protected by a customer-supplied shelter. Primary liquid level sensing is by a pressure transducer with floats as a backup.
