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.

A new Walmart Supercenter required this package stormwater pump station to handle runoff from its large impervious parking lot. A good sized detention basin collects the runoff water during a storm event, including from surrounding properties. Ebara submersible pumps then empty the detention pond at a high flow rate through just 45’ of force main into a gravity line that flows to treatment. An outdoor UL listed control panel includes float controls for primary and backup liquid level-sensing and a basic alarm for communications.
