After the historic Bay Meadows racetrack closed down, a large residential development began that required this large wastewater lift station. A triplex configuration of 30 hp Flygt pumps handles the high flow rates of this system. A blower system was provided as part of the lift station odor control specified by the City. The lift station electrical controls comprised a PLC, float control level-sensors, and a backup generator. The panel includes an Arc Armor® enclosure that provides safe access to low-voltage controls and separate access for high-voltage circuits.

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.

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.
