Tennessee Septic Regulations

Tennessee septic systems are regulated by the Department of Environment and Conservation (TDEC) through the Division of Water Resources. Permits are required for all new installations and repairs. Time-of-transfer inspections are not mandated statewide but may be required by lenders.

• Septic permits are issued by TDEC's Division of Water Resources through local county health departments.
• A site evaluation including soil analysis is required before permit approval.
• Tennessee's karst geology (limestone bedrock) in areas like Chattanooga and Knoxville requires special consideration for drain field placement.
• Tennessee does not mandate a time-of-transfer septic inspection, but FHA and VA loans typically require one.
• Pumping frequency: typically every 3 to 5 years depending on tank size and household.
• TDEC maintains a database of permitted systems — contact the local environmental field office for records.
