Contech Engineered Solutions needed this pump station to pump medium flows of clean water from a Contech filtration system to a nearby treatment pond. This system was designed with 5 hp Ebara pumps in a duplex configuration. A precast concrete wet well includes a pedestrian rated hatch and safety grate for reliable fall protection. Valve “cans” were included in the design and supply of this system for an economical control valve option. The control panel was a UL listed device in an outdoor enclosure, including a pressure transducer control device for redundancy.

A new 144,000 square feet, two building industrial center needed a large stormwater pump station to handle the runoff from the site. This triplex system includes a fourth, “jockey” pump to handle low flow dry-season runoff. The three large pumps are 20 hp Ebara submersible pumps designed for redundant pumping during high flow events. A pressure transducer serves as the primary level-sensing device and operates inside of a perforated stilling well designed to prevent solids from interfering with the sensor. The electrical controls are configured with a logic relay, intrinsically safe circuits, and communications.

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.
