How do you get a septic permit in Georgia?
In Georgia you get a septic permit from the county Environmental Health office before any work starts. The office reviews the site and soil, then must approve or deny a complete application within 20 days. The permit lasts up to 12 months, and the system cannot be covered or used until the county's final inspection.

Plain definitions
Permit vocabulary
- Septic letter
- In Greene County, the septic letter is Environmental Health's written approval of a lot for septic, which the county building office requires with any building permit that will use a septic system.↗
- Level 4 soil investigation
- A Level 4 soil investigation is the most detailed soil study in Georgia's manual, and every drip dispersal permit requires one.↗
- Soil classifier
- A soil classifier is a DPH-certified professional who evaluates soils for septic suitability; Georgia requires those doing soil evaluations to carry at least $1 million in liability insurance.↗
- Final inspection
- The final inspection is the county's look at the finished, still-uncovered system, and written approval must follow before the trenches are backfilled or the house uses it.↗
How the job runs
The permit sequence, step by step
- 1
Rule out sewer
If a public or community sewer is available within 200 feet of the property line, Georgia requires connection instead of septic. Around the lakes, ask Piedmont Water about Reynolds, Great Waters and Cuscowilla lots, and the city or county utility near Eatonton, Madison, Milledgeville and Sparta.

- 2
Line up the well first if you need one
North Central Health District counties want the private well permit applied for first, and its fee includes a site evaluation to place the well. The well location then sets the 100-foot circle the drain field must stay out of.
North Central Health District: Putnam County Environmental Health Department
- 3
Site and soil evaluation
The county, sometimes with a certified soil classifier's report, judges soil depth, slope and seasonal water. Do not grade first: Georgia requires soil and percolation work to be redone if cuts or fill change the field depth.
GA DPH Manual for On-Site Sewage Management Systems (March 2026), Section B: General Site Provisions
- 4
Application and design
Apply with the bedroom count and a site plan showing the tank, field and repair area. Tanks start at 1,000 gallons for up to four bedrooms. The county decides within 20 days of a complete application.
511-3-1-.03; .05Ga. Comp. R. & Regs. r. 511-3-1-.05, Septic Tanks (LII)
- 5
Installation inside the permit window
Georgia requires septic tank contractors to be certified by DPH, renewed every two years. Ask any installer for their current certification before work starts, and build what the permit shows within its 12-month life.
- 6
Inspection, then backfill
Leave everything open for the county inspector. After written approval, protect the field: later grading or filling that may affect the system voids that approval.

How it varies by county
Call the Environmental Health Manager at 706-453-4471 for a septic letter or perc test; specialists are at 1031 Apalachee Avenue, Greensboro, 8:30 to 10 a.m. weekdays. Lots need 0.75 acre on public water or 1.5 acres on a well, not counting land within 75 feet of Lake Oconee's high-water line.↗
Morgan County Environmental Health, 2005 South Main Street, Suite 200, Madison, 706-752-1266 option 3, keeps short morning in-office hours. Its 2024 schedule adds a $50 location plan review, a $75 site plan review and a $75 expedited service option.↗
117 Putnam Drive, Suite C, Eatonton; (706) 485-8591; weekdays 8 a.m. to 4:30 p.m. DPH's statewide phone list gives (706) 484-2914, so try both if one does not answer.↗
100 Ireland Drive, Milledgeville; (478) 445-1591; weekdays 8 a.m. to 4:30 p.m. Covers Lake Sinclair's south shore around Milledgeville.↗
516 Boland Street, Sparta; (706) 444-6616. The specialist is in the county only on Tuesdays and Thursdays, so a missed call can cost most of a week.↗
825 Eatonton Street, Monticello; (706) 468-6850; weekdays 8 a.m. to 4:30 p.m.↗
114 Forest Street, Gray; (478) 986-3164; weekdays 8 a.m. to 4:30 p.m.↗
The whole story
What lake lots add to the paperwork
On a Lake Sinclair lease lot, the septic permit is one of several documents Georgia Power asks for before it reviews a new house: the county-approved site plan showing tank, drain lines and well, the septic permit, the building permit, a land disturbing permit if more than an acre is disturbed, and any county buffer variance. Get the county septic approval first, because Georgia Power's review starts from it.
Erosion permits matter on the water too. Greene County requires an erosion plan, a land disturbance permit and an EPD Notice of Intent for work within 200 feet of state waters or in a post-2000 common development, and it notes a state-mandated 14-day wait after the NOI is filed before permits issue. Build that two weeks into the schedule.
Lot size can end the conversation early. Greene's 75-foot exclusion along Lake Oconee and Morgan's planning figure of 0.6 acre for septic, or 1.2 acres with a well and septic on the same lot, both bite hardest on small, older lake lots.
FAQ
Septic permit questions
Straight answers, with the rule or record behind them. Still unsure? Call and ask the crew that digs.
(678) 863-5620How long does it take to get a septic permit in Georgia?
The County Board of Health must approve or disapprove a complete application within 20 days of receiving it. Real timelines run longer when soil work, a well permit or Georgia Power review is needed first. In Hancock County, the specialist's Tuesday and Thursday schedule also stretches things.
Where do I apply for a septic permit in Putnam County?
Putnam County Environmental Health, part of the North Central Health District, at the health department, 117 Putnam Drive, Suite C, Eatonton. The office lists (706) 485-8591 and is open 8 a.m. to 4:30 p.m. weekdays, closed state holidays. The district does not post a septic fee schedule.

What is a septic letter in Greene County?
It is the Environmental Health approval the Greene County building office needs with any building permit that will use septic. Call the Environmental Health Manager at 706-453-4471 to request the septic letter or a perc test before you apply to build.
Do I need a permit to repair my septic system?
Yes. Georgia's rule says repairs, replacements and additions to existing systems must be permitted and inspected. Greene and Morgan both list a $200 residential repair permit and $300 for commercial under their August 2024 fee schedules.
Source: Morgan County EH fees, effective August 1, 2024 (Northeast Health District)
Can I start clearing my lake lot before the septic permit?
Be careful. Grading or cuts that change the depth of a proposed absorption field mean the soil evaluation and percolation tests must be redone, and heavy equipment can compact the best soil on the lot. Mark the field area and keep machines off it until the county has reviewed it.

What happens if my septic permit expires?
Georgia construction permits are valid for no more than 12 months from issue. If the system is not installed and inspected by then, contact the county office about reapplying before any work continues.
Can I landscape over my new septic system?
Light landscaping, yes; regrading, no. Georgia's rule says grading, filling, digging or construction after approval that may adversely affect the system voids the county's approval. Keep patios, drives and fill off the field and the reserved repair area.
Does a drip or aerobic system need a different permit?
The permit is the same type, but the paperwork is heavier. Drip permits require a Level 4 soil investigation and a design from a DPH-approved manufacturer or a Georgia registered engineer, and an engineer is required above 2,000 gallons per day.
