Component Repairs
| Repair Type | Cost Range | Notes |
|---|---|---|
| Baffle or tee repair | $150–$500 | Left unaddressed, sends solids to drainfield |
| Pump replacement | Moderate | Common on sloped Georgia lots with pump chambers |
| Tank replacement | Major | Post-2000 replacements must be two-compartment |
| Drainfield replacement | EPA national range: $5,000–$15,000 conventional, more if engineered | Region and soil dependent — see table below |
Why Drainfield Costs Escalate on Piedmont Clay
When a drainfield fails, a repair permit from the county requires a new soil evaluation. That evaluation determines whether a conventional replacement is feasible or whether the property now requires an engineered alternative system. On Piedmont clay, the answer is frequently the latter — the tight soils that contributed to the original field’s failure often don’t support a conventional replacement under current code. That’s where a a conventional repair becomes a materially more expensive engineered system.
The replacement field must go in undisturbed soil — not in the same footprint as the original. Properties without enough undisturbed area for a new field face extremely limited and expensive options.

What Your County Charges — Where Georgia Publishes It
Georgia sets septic fees county by county, under O.C.G.A. 31-3-4. There is no state schedule and no district schedule — District 4 publishes nothing at all across its twelve counties. Of the nineteen counties we cover, five publish a fee schedule we can read. Here they are, with what is wrong with each one.
Every figure here comes from that county’s own published schedule, with the date it carries. Fee authority in Georgia is per-county by statute, so we will never print a neighboring county’s number on your county’s page — it would be wrong. Where a county is not listed, it publishes no schedule we could retrieve, and that is not the same as there being no fee. We hold no sourced figure for what a complete septic installation costs in Georgia and will not print one.
Repair vs. Replacement: How to Tell
A useful rule of thumb: if the problem is inside the tank (baffles, pump, filter, tank walls), it’s usually a component repair at the lower end. If the problem is in the drainfield (surface seepage, saturated soil, failed distribution lines), you’re likely looking at a field replacement at the higher end.
There’s a middle ground — sometimes what appears to be a drainfield problem is actually a tank issue. A failed baffle or clogged effluent filter can send solids to the field, causing temporary saturation that resolves once the tank issue is fixed and the field rests.
Georgia requires a permit for any septic repair. Your county Board of Health environmental health office issues repair permits. Among the Georgia counties that publish a fee, they run $100 to $200 — $100 in Paulding and Fayette, $150 in DeKalb, $170 in Cobb and Douglas, and $200 in Walton. Only DPH-certified installers may perform the work.

Frequently Asked Questions
How much do septic repairs cost in Georgia?
It depends on whether a component failed or the drainfield failed, and those are very different jobs. The EPA puts repair or replacement of a conventional system at $5,000 to $15,000 nationally, and says alternative systems cost more. No Georgia agency publishes a repair cost figure.
Do I need a permit for septic repairs?
Yes. County Board of Health issues repair permits. Only DPH-certified installers may do the work.
Repair or full replacement – how do I tell?
Tank-side problems are usually component repairs. Drainfield problems typically mean field replacement.
Why do repairs cost more on Piedmont clay?
Soil evaluation during repair permitting often shows conventional design is no longer code-compliant.
