A new wastewater treatment plant was placed in operation in 2000. The staff at the Murfreesboro Water Resources Recovery Facility (MWRRF) are responsible for ensuring that pollutants and harmful nutrients are removed from the wastewaters of the City’s domestic and industrial customers.
The plant is permitted to treat 16 million gallons per day (MGD).
The MWRRF provides primary treatment of the influent flow using step screening and a vortex grit removal process. Secondary treatment is carefully controlled multi-stage biological process that includes various microorganisms metabolizing nutrients to meet TDEC National Pollutant Discharge Elimination System (NPDES) permit requirements.
The water is then filtered, disinfected by ultraviolet light, and aerated before discharge to the West Fork Stones River. The resulting reclaimed water, on par with the drinking water standards of the 1970’s, ensures that all downstream users and aquatic life are protected from harmful contaminants that could otherwise enter the waterway.
