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.

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.

A growing resort community with golf courses needed this Romtec Utilities package lift station to meet super high sewage flows with high head conditions. The resort has ample property for expansion and needed a wastewater lift station that would also expand. Two submersible solids handling pumps were included in the original supply, but the mounting hardware for a third pump in a triplex configuration was included to allow easy expansion as more condos are constructed. An outdoor control panel is protected by a shelter and utilizes a pressure transducer and backup floats for liquid level-sensing.
