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 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.

These three package lift stations were designed to meet medium flows of industrial process water with added low flows of industrial stormwater and wastewater. Submersible centrifugal pumps in a duplex configuration were specified to meet the peak flows and water chemistry identified for each pump station. UL listed control panels with floats for liquid level-sensing and basic alarms comprise the system controls for the lift stations. These packaged lift stations were integrated into stormwater, processing, and wastewater plans for the new construction of the Colusa Generating Station.

A remote Tesoro Corporation industrial site needed this stormwater pump station to handle water discharged from an oil/water separator which processes on-site runoff. Submersible centrifugal pumps were used in a duplex configuration in this shallow wet well. The 7.5 hp Ebara explosion-proof pumps were sized to meet low flow, medium head conditions for stormwater. Check valves and plug valves were integrated into the discharge piping in the well for a simple and cost-effective design. The precast concrete wet well and the access hatch are both pedestrian rated.

The US Army Corps of Engineers worked with Romtec Utilities to design this lift station to replace an existing septic system. The resulting package wastewater lift station met the high sewage flows of this publicly owned industrial complex. The submersible sewage pumps in a duplex configuration are explosion proof to meet the wet well space classification. An outdoor UL listed panel utilizes floats and a pressure transducer for intrinsically safe level controls. It also includes an autodialer for communications and a blower for odor control.
