County health, not a state portal
Richmond County falls under the East Central Health District, District 6, reachable at (706) 721-5800. There is no state ePermitting system like SCDES on this side. The application goes to the county.
Twelve months, not five years
A Georgia construction permit is valid for twelve months. In South Carolina it is five years. If your build slips, that difference is the thing that bites you.
Inspected before backfill, every time
Georgia requires a County Board of Health inspection before the system is covered. There is no self-inspection option here, unlike South Carolina where a Tier 3 installer may inspect their own work. Schedule accordingly.
Augusta sits on the Fall Line
The Fall Line runs northeast straight through Augusta, which means soil can shift from Piedmont clay to Coastal Plain sand across relatively short distances. Two lots a mile apart can need genuinely different systems.
