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.

This food processing plant in Benicia, California needed a wastewater lift station to handle combined sewage and process water from the production of pasta. The lift station design included Tsurumi grinder pumps in a duplex configuration. These submersible grinder pumps were included to handle pasta and cheese that occasionally get into the process water. The system electrical controls comprise a standard UL listed panel with float controls for liquid level sensing. The lift station pumps into an existing sewer main and on to treatment.

This package lift station was designed to meet the medium wastewater flows of this California prison. Solids-handling pumps in a duplex configuration are protected from cascading influent by a drop bowl. The liquid level-sensing is controlled by a pressure transducer and a float in used for emergency backup. A below-grade valve assembly holds the system’s valves, flow meters, and pressure gauges. An outdoor PLC panel with a basic alarm and an added input for a radio modem comprise the systems controls.
