How do septic permits work in Greenville County, SC (SC DES)?
In South Carolina, septic systems are permitted by SC DES (the SC Department of Environmental Services, formerly DHEC). For a new system, the property owner applies for an onsite wastewater permit; SC DES evaluates the soil/site and issues a permit that specifies the system type and layout; a licensed installer like RW Grading then installs it to that permit, and SC DES inspects and approves it before it's covered. Repairs and tank replacements may also need a DES permit. RW Grading can help you through the process.
