The Water Reclamation Division of the Water Management Department includes Wastewater Collection and Wastewater Treatment (Water Reclamation Facility) . This division takes a proactive approach to operations through ongoing inspections and replacement of aging infrastructure to ensure adequate conveyance and treatment of wastewater.
Water Reclamation Facility: an activated-sludge treatment facility with nutrient removal, tertiary filtration, and ultraviolet light disinfection. The City currently has a National Pollutant Discharge Elimination System (NPDES) Permit for discharge of sixteen (16) million gallons per day (MGD). Effluent limits on constituents were established by the Tennessee Department of Environment and Conversation (TDEC) through extensive studies performed by the Environmental Protection Agency (EPA) on the Harpeth River. The City was the first in the state to operate a reclaimed water network, that uses effluent for irrigation purposes within the City.
The City consistently outperforms the permit requirements and is among the top performers of wastewater treatment in the state.
Wastewater Collection: includes gravity sewer lines, forcemains, and pump stations located throughout the service area. These mains that run under the ground convey wastewater to the WRF. Under the Wastewater Collection Division, staff is responsible for the maintenance, replacement, and extension of the wastewater collection system through the use of capital improvement projects, new development, and replacement of aging infrastructure.
