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.

The Union Pacific Depot in Cheyenne, Wyoming needed two new sewer lift stations to replace its existing sewer collection system. Each lift station included three precast concrete vault structures, a wet well, valve vault, and metering vault. Both systems use 2 hp Ebara Vortex® sewage pumps in duplex configurations that are explosions proof rated for Class I, Division I locations. The valve assemblies comprise Val-Matic Cam-Centric® plug valves and Swing-Flex® check valves with pressure gauges. Endress and Hauser PROline® electromagnetic flow meters measure the sewage flows for both lift stations. These in-ground valve and meter assemblies were fitted with heat tracing to provide reliable frost protection with Raychem and Digitrace components.
