About the WWTA

The Hamilton County Water & Wastewater Treatment Authority (WWTA) is responsible for the public sewer system throughout the unincorporated areas of Hamilton County, Tennessee and the surrounding municipalities of East Ridge, Lakesite, Lookout Mountain, Red Bank, Ridgeside, Signal Mountain, and Soddy Daisy. The WWTA is not responsible for sewers in the City of Collegedale, the Town of Walden or the City of Chattanooga.
The purpose of the WWTA is to protect the environment and the public by regulating the quality of water discharged into the wastewater collection system and treatment works, regulating the quality of construction of extensions to the sewer, and encouraging the expansion of sewers of the wastewater collection system. The WWTA has established regulations to ensure its compliancy with the provisions of the Clean Water Act and other applicable federal, state and local laws, regulations ordinances and with any other requirements of orders, consent decrees, and/or mandates established by the Environmental Protection Agency (EPA) or the Tennessee Department of Environment and Conservation (TDEC), including permits for authorization to discharge under the National Pollutant Discharge Elimination System (NPDES) and State Operating Permit (SOP); and its customers’ compliance with these rules and regulations, rate schedules for wastewater service adopted by the WWTA Board and any rules of procedure established by the WWTA Board to implement these rules and regulations.

The WWTA was created in 1993 by the Hamilton County Commission in accordance to the Water and Wastewater Treatment Authority Act, T.C.A. 68-221-601. The WWTA collection system is composed of over 500 miles of collection lines, 60 pump stations, 900 grinder pumps, 2 wastewater treatment facilities, and services over 30,000 sewer customers. In December of 2012, the WWTA began sewer billing for customers who receive water services from Tennessee American Water (TAW).

The WWTA operations are entirely supported by revenues generated through construction projects, permits, inspection fees and sewer usage fees. No tax dollars are provided for the operation of the WWTA’s wastewater collection systems and treatment works. It is the WWTA Board’s judiciary responsibility to provide reliable and courteous sewer service within its service area in order to promote economic development, eliminate health problems, and to protect the environment.
