How does the Groundwater Division help keep Knox County healthy?
The mission of the Groundwater Protection Division of the Knox County Health Department is to protect the groundwater supply and environment from pollutants by enforcing the laws governing onsite wastewater systems.
This division regulates the installation of subsurface sewage disposal systems (SSDS). All residential and commercial facilities not connected to public sanitary sewer must have a SSDS to receive and treat all wastewater generated within the facility.
Our environmental specialists assist property owners in evaluating, designing, and inspecting all SSDS installed in Knox County.
Tennessee Department of Environment and Conservation (TDEC) regulations and statutes govern the Knox County Health Department Groundwater Division. SSDS regulations and information can be accessed by clicking here.
