Wayne County awarded a significant contract for SCADA, Disinfection & Meter Improvements for the Rouge Valley Sewer District & CSO to J. F. Cavanaugh. In turn, Cavanaugh selected Rotor Electric of Michigan, LLC to provide the necessary $2.6 million of electrical and electronic equipment and installation to complete the upgrades and improvements successfully. Construction teams completed the work over 17 months.

The North Huron Valley-Rouge Valley (NHV-RV) Sewer District serves most of Wayne County and a small portion of Oakland County. The district also currently accepts wastewater from the Western Townships Utility Authority (WTUA). The district covers 274 square miles, an estimated 55% of which is sewered.

The Lower Rouge subdistrict is served by an interceptor system that parallels the lower branches of the Rouge River. The Middle Rouge subdistrict is served by the Upper Rouge and Middle Rouge interceptors, which combine with Detroit’s Evergreen Sewer at Ford Road. There are several CSO and wet weather flow basins in the district and 48 regulators.

The SCADA, Disinfection & Meter Improvements for Rouge Valley & CSO project replaced outdated control system software and instrumentation at Lift Station 1A, the Livonia (Inkster Arm) Sanitary Equalization Basin, and at collection system remote facilities (including replacement of Doppler flow meters).
