After the historic Bay Meadows racetrack closed down, a large residential development began that required this large wastewater lift station. A triplex configuration of 30 hp Flygt pumps handles the high flow rates of this system. A blower system was provided as part of the lift station odor control specified by the City. The lift station electrical controls comprised a PLC, float control level-sensors, and a backup generator. The panel includes an Arc Armor® enclosure that provides safe access to low-voltage controls and separate access for high-voltage circuits.

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.
