A new development for a commercial park needed this wastewater lift station to connect the development to the municipal sewer system. Submersible centrifugal pumps in a duplex configuration were engineered to meet the medium flow high head conditions of the force main. This system needs to pump at a predefined flow rate in order to achieve the minimum force to reach the existing municipal sewer lines. The lift station control panel is a UL listed panel with redundant float controls wired for intrinsically safe use.

This municipal lift station replacement was configured to handle medium flows of sewage from a large area of Wenatchee, Washington. This deep wet well was constructed from precast concrete and includes Tnemec interior coating. Vaughan Chopper Pumps in a duplex configuration were selected to macerate solids and alternate pumping cycles. A PLC with a touchscreen interface provides an easy and flexible control panel. The primary level-sensing device is a pressure transducer with floats backup level-sensing. This control panel also uses soft starters to reduce current inrush to the 30 hp pumps.
