Louisville, KY

  • 138,000
  • 1.2



Built in 1957, the Louisville Metropolitan Sewer District’s Western Flood Pump Station is one of the largest in the city. The station safeguards 138,000 west Louisville residences from flooding, in this combined sewer overflow (CSO) service area. This project was art of the scope for upgrading and refurbishing the plant.

Intellimodus, formerly ControlTouch Systems, partnered with the TEM Group to provide the control system design, instrumentation, and HMI system for the refurbished pumping station. The new control system communicates with the Motor Control Centers (MCCs) over the Modbus for control and monitoring of the high voltage equipment. TEM provided the field wiring and electrical installation for the project.

  • Accomplished while the station remained in service
  • Collaborative project with TEM Group and GRW


GRW was the lead design firm for the design-build of the 1.2 billion gallon per day (BGD) Western Flood Pumping Station renovation project which involved replacement of seven vertical pumps, seven motors, pump lubrication systems, bar screens and trash removal system, three 48-inch gate valves and flap gates, four 72-inch multi-shutter gates, a 30-ton bridge crane, and structural improvements to accommodate the pumps and motors. All of this work occurred while the pump station remained in service with no more than one pump out of service at a time.
