A septic permit still comes from the state through SCDES's onsite wastewater program, even though the local contact point is inside the county health department building. Getting a new permit follows this process:
- We submit your address and parcel number to that office.
- A soil classifier checks groundwater depth, drainage, and what the lot can support. This is the state's site evaluation, which carries its own $150 fee.
- SCDES reviews the plan and issues the permit once the design meets requirements.
- Once installation is complete, an inspection confirms everything that's been approved.
As of August 2026, having Rock Solid manage this whole process runs $1,500–2,500 depending on site conditions. About 95% of the installs John sees come with a permit already in hand from the builder or the homeowner. When they don't, we handle the application online. You show where the structure and the septic system will sit, and SCDES contacts you to schedule the field evaluation. Then we come out with an excavator to dig the locations the inspector requests. John's typical turnaround for approval is 1.5 to 3 weeks (as of September 2026, and it varies).
