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.

The newly constructed headquarters for the Sacramento Municipal Utility District purchased this package lift station to meet its medium sewage flow requirements. Submersible solids-handling pumps in a duplex configuration were specified in a deep well because this facility represents one of the ten largest public utilities in the country.

To create new potable water, this lift station pumps clean stormwater from a collection/storage basin to a treatment facility. Duplex vertical turbine pumps move high flows of water very efficiently and use soft starters to reduce torque on the vertical shaft and provide additional pump diagnostics. Also included is an above-grade valve assembly on the top slab. The control panel utilizes an ultrasonic transducer for primary level controls and a pressure transducer for backup. The entire package lift station is located inside an owner-supplied control building.
