The Union Pacific Depot in Cheyenne, Wyoming needed two new sewer lift stations to replace its existing sewer collection system. Each lift station included three precast concrete vault structures, a wet well, valve vault, and metering vault. Both systems use 2 hp Ebara Vortex® sewage pumps in duplex configurations that are explosions proof rated for Class I, Division I locations. The valve assemblies comprise Val-Matic Cam-Centric® plug valves and Swing-Flex® check valves with pressure gauges. Endress and Hauser PROline® electromagnetic flow meters measure the sewage flows for both lift stations. These in-ground valve and meter assemblies were fitted with heat tracing to provide reliable frost protection with Raychem and Digitrace components.

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.

City of Shafter in California

A suburb of the City of Shafter required a lift station package to repair and rehabilitate an existing wastewater sump. Duplex submersible centrifugal pumps and discharge pipe mounting brackets were fitted to a concrete slab poured in the bottom of the existing manhole. The Romtec Utilities package included the proper components to operate in this 26-foot-deep sump. An outdoor MultiSmart control panel utilizes conductive probes for primary and backup level controls and an autodialer for communications. This retrofit package saved about 60% the cost of a new lift station.

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.

The City of Brawley needed this packaged lift station to handle high flows of wastewater at its municipal treatment plant. 12 HP submersible pumps in a duplex configuration were used to meet the high flow pumping needs and a conductive probe was used for liquid level-sensing. The in-ground valve assembly and meter assembly were each located in separate vault structures for a cost effective design and easy access. An outdoor, UL listed control panel was protected from weather and sunlight by a six-post shelter, which also covers the sump entry hatch and electric disconnect panel.
