Septic Installation services in Georgia

New septic system installation in Georgia requires a permit from the county board of health, issued under DNR EPD's On-Site Sewage Management regulations (Chapter 290-5-26). The permitting process includes a site evaluation with soil analysis, percolation testing, and a determination of the seasonal high water table. Georgia requires a minimum lot size for septic systems — typically 0.75 to 1 acre — though some counties have adopted stricter standards.

Conventional gravity system installation in Georgia costs $3,000–$10,000, with most installations falling in the $4,000–$7,000 range. Engineered systems — including low-pressure dosing, aerobic treatment units, and drip dispersal — can run higher, particularly in north Georgia's mountain counties where rocky terrain and steep slopes limit conventional options. The Coastal Plain's sandy soils generally support conventional systems well, keeping costs lower in that region.

The Piedmont's red clay presents the most common installation challenge in Georgia. Slow percolation rates in clay soil mean larger drain fields and, in some cases, modified systems with imported fill material. Contractors in the Atlanta metro area report that challenging Piedmont sites can push total costs to $8,000–$10,000 even for conventional designs. County permit fees range from $200–$500, and soil evaluation fees add another $300–$600. Georgia requires both a rough-in inspection and a final inspection before the system is approved for use, and all work must be performed by a licensed installer.

Why choose a licensed provider?

Georgia requires licensing for septic system contractors and well drillers to protect public health and the environment. A listing does not establish that a business meets those requirements. Confirm current licensing, insurance, and scope of work with the business and issuing authority before hiring.
