How do septic permits work in Anderson County, SC?
The South Carolina Department of Environmental Services, not Anderson County, permits residential septic systems.
The South Carolina Department of Environmental Services, not Anderson County, permits residential septic systems3. A home or manufactured home without public or community sewer needs SCDES approval and a Permit to Construct before Anderson County can issue the building permit3. The application fee is $150, and the permit is valid for five years unless renewal or modification requires a new application and fee3. For application questions, call SCDES at 1-855-731-250425.
After installation, the installer must contact SCDES before covering the system; SCDES requires a final inspection and issues approval to operate if the system meets state standards; a licensed installer may self-inspect and submit the approved form if the inspector does not arrive within 30 minutes of the scheduled time26. Sites above South Carolina's Fall Line need backhoe pits for the soil evaluation, and the applicant arranges the operator3. About 80.6% of Anderson County's soils are free of severe limits for a conventional drain field27. SCDES cannot issue a septic permit where public sewer is accessible28.
