A remote Tesoro Corporation industrial site needed this stormwater pump station to handle water discharged from an oil/water separator which processes on-site runoff. Submersible centrifugal pumps were used in a duplex configuration in this shallow wet well. The 7.5 hp Ebara explosion-proof pumps were sized to meet low flow, medium head conditions for stormwater. Check valves and plug valves were integrated into the discharge piping in the well for a simple and cost-effective design. The precast concrete wet well and the access hatch are both pedestrian rated.

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 City of Santa Barbara needed this packaged pump station to manage low stormwater flows from events that occur during the dry season. Duplex submersible pumps capable of passing a 3-inch solid pump the water into an existing sanitary sewer pressure main and on to treatment. This pump station includes an in-ground valve vault with plug and check valves and stainless steel discharge piping to handle oily or contaminated water conditions. Romtec Utilities supplied the complete electrical controls with liquid level sensing, alarm notifications, pump start and stop cycles, above-grade disconnect stand, and intrinsically safe circuits.

An IMTT industrial storage facility needed this stormwater pump station to collect runoff and pump it to treatment onsite. The duplex submersible pumps were engineered to handle the expected medium flows of stormwater. The pumps also needed to handle water that could potentially carry oil or other industrial chemicals stored on the site. An above-grade valve assembly used ball valves and check valves that were vertically integrated for easy access. The pump station electrical controls were located on an existing wall in the water treatment area.

Solyndra Commercial Complex

This new commercial complex required two new stormwater pump stations designed to meet low flows of runoff. The manholes and hatches were designed at grade to integrate seamlessly with the brick patio and walkway. Submersible centrifugal pumps in a duplex configuration discharge to below grade valve assemblies accessible by valves cans. The UL listed control panels are contained by stainless steel NEMA enclosures and include intrinsically safe barriers. Both lift stations were designed with the same primary components for site standardization.
