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.

The Union Pacific Depot in Cheyenne, Wyoming needed two new stormwater pump stations to replace existing systems. The first station used Ebara 25 hp submersible pumps in a triplex configuration to handle stormwater runoff from a parking lot and additional drains. The second station used Ebara 7.5 hp submersible pumps in a duplex configuration to pump stormwater that drains from the pit of a railway turntable. Both systems include precast concrete valve vaults. Each vault was preassembled with Val-Matic Cam-Centric® plug valves, Val-Matic Swing-Flex® check valves, and Ashcroft pressure gauges. Both stormwater systems discharge into an evaporation pond that was installed as a part of this larger water collection replacement, which also included three additional Romtec Utilities wastewater lift stations.

The US Army Corps of Engineers worked with Romtec Utilities to design this lift station to replace an existing septic system. The resulting package wastewater lift station met the high sewage flows of this publicly owned industrial complex. The submersible sewage pumps in a duplex configuration are explosion proof to meet the wet well space classification. An outdoor UL listed panel utilizes floats and a pressure transducer for intrinsically safe level controls. It also includes an autodialer for communications and a blower for odor control.

An expanding sewer system for annexed land required this packaged wastewater lift station. Duplex submersible solids handling pumps are designed to meet the medium flow requirements and pass solids up to a 2” diameter. To save space, the system valves are integrated into the discharge piping in the sump. An outdoor control panel utilizes floats for liquid level-sensing and an intrinsically safe barrier for in-well electrical components. The electrical controls are wall mounted.
