WWTA In Your Community

The Hamilton County Water & Wastewater Treatment Authority (known as the WWTA) was created in May 1993 by the Hamilton County Commission according to the Water and Wastewater Treatment Authority Act, T.C.A. 68-221-601. The purpose of the WWTA is to set uniform requirements for users of the wastewater collection system to enable the WWTA to comply with the provisions of the Clean Water Act and other applicable federal, state and local laws and regulations, and to provide for the public health and welfare by regulating the quality of wastewater discharged into the wastewater collection system and treatment works by regulating the quality of construction of extensions to the system.

The 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 governed by a Board of Commissioners composed of five members appointed by the county Mayor according to the Act and a representative from each municipality that has joined the WWTA. The governing board holds a public meeting the third Wednesday of each month at 3:30 pm in the Development Resource Center, 1250 Market Street, Chattanooga, Tennessee.
