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.
