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. Official steps are on the SC DES residential septic page: https://des.sc.gov/permits-regulations/septic-tanks/permits-licenses/septic-tanks-residential-single-home-builder
How long does a septic tank replacement take?
A straightforward septic tank replacement is often one to two days on site after the permit is in hand and the old tank has been pumped. Access, weather, and what the SC DES permit requires can change that. Your written quote names the expected days for your property.
