City Avoids Full Shutdown Of Wastewater Facility For Repairs With Valve Insertion

The Problem

The City of Tuscaloosa’s Infrastructure and Public Services department owns, operates, and maintains the Hilliard N. Fletcher Water Resource Recovery Facility, a conventional activated sludge facility with a permitted treatment capacity of 24 million gallons per day.

Isolation valves installed on the discharge segments of each pump had reached the end of their useful life and, due to the necessary continuous operation of the pump station, shutdowns and bypass pumping was not a realistic nor costeffective solution.
