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 Shafter|Shafter, CA|400 GPM - 28.5' TDH
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.
West Mesa Industrial Park|Las Cruses, NM|733 GPM - 44' TDH
The US Army Corps of Engineers worked with Romtec Utilities to design this lift station to replace an existing septic system. The resulting package wastewater lift station met the high sewage flows of this publicly owned industrial complex. The submersible sewage pumps in a duplex configuration are explosion proof to meet the wet well space classification. An outdoor UL listed panel utilizes floats and a pressure transducer for intrinsically safe level controls. It also includes an autodialer for communications and a blower for odor control.
Santa Barbara County|Goleta, CA|50 GPM - 28' TDH
Santa Barbara County needed this package lift station to replace an existing system serving a residential area next to Goleta Beach. Ebara submersible sewage pumps were engineered in a duplex configuration to alternate starts and create redundancy in the system. Liquid level-sensing also includes redundancy by using Dwyer floats as the primary control device and a Multitrode probe for high-level backup. A UL listed control panel uses a NEMA 4X stainless steel enclosure to be safely located outside of the existing control building.
The City of the Dalles | The Dalles, OR | 38 GPM - 28.2' TDH
The City of the Dalles required this replacement package lift station to meet medium flows of municipal wastewater. This lift station included submersible centrifugal pumps in a duplex configuration with the ability to handle some suspended solids. The control panel for this lift station includes SCADA software to interact with a remote telemetry unit (RTU). These two systems provide communications from the pressure transducer and conductive probe level sensing devices. They also communicate calculated flow rates and any voltage variances in from the power supply.
