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.

A new commercial development where a Goodwill retail store was being built needed this robust wastewater lift station. The hatch and below-grade structural components of this lift station have an H-20 rating for occasional traffic so that the system could be located in the parking lot of the development. This also included a below-grade, explosion proof electrical junction box. Goulds vortex pumps in a duplex configuration were chosen to handle unknown solids from future tenants of the development. Electrical controls were provided through a standard UL listed panel.

Romtec Utilities designed and supplied this wastewater lift station retrofit to meet the medium sewage flows at the Steven’s Pass Ski Resort. A major part of the retrofit supply package were two Vaughan submersible chopper pumps for wastewater. The electrical controls were the next significant portion of the retrofit. The PLC controller included a touchscreen HMI with autodialer telemetry and SCADA options to communicate with the resort treatment plant. This communication provides advance notification for the treatment plant as the lift station is nearly inaccessible during winter months.

An RV park needed this package lift station to meet the municipal sewage requirements for the residents at the park. Pumping with low flow and low head conditions, the duplex Goulds submersible pumps are sized to efficiently fit the 14’ deep, 4’ diameter wet well. An outdoor UL listed control panel utilizes floats for liquid level-sensing and includes an autodialer for communications and alarm notifications. The complete system was installed at finish grade with traffic rated hatches to provide a low profile for the residential area.

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.
