Septic repair on the Georgia side of the line

Fort Oglethorpe, Ringgold, Rossville, Chickamauga, Flintstone, LaFayette: tens of thousands of households a few minutes from Chattanooga, under a completely different septic regime. Calls from the Georgia side are routed to companies that work these counties; the paperwork is what changes at the border.

Georgia runs septic through the county, not the state

In Tennessee, a state agency (TDEC) permits septic work. In Georgia, the authority is your county health department under the state public health rules (chapter 511-3-1). The rule is blunt: no lot development, no installation, and no component work without a construction permit from the county health department first. Repairs, replacements, and additions "must be permitted and inspected" too.

Who to call for permits, by county
CountyOfficeWherePhone
Catoosa Catoosa County Environmental Health (NW Georgia Health District) 182 Tiger Trail, Ringgold, GA 30736 (706) 406-2030
Walker Walker County Environmental Health 101 Napier Street, Suite B, LaFayette, GA 30728 (706) 639-2574

The fees on the posted schedules

Per the county fee schedules the health district currently posts: in Catoosa County, a new-system application with site visit runs $275, a repair permit $100, and an existing system evaluation $125. In Walker County: $175 for the application and site visit, $75 for an existing system evaluation, and $100 for a lot evaluation when you're buying land. Both counties charge a stiff "delayed permit" penalty ($500 Catoosa / $350 Walker) for work started before permitting, which is a good reason not to let anyone talk you into digging first. The posted schedules carry older effective dates, so confirm amounts when you call.

Georgia's certification rules are their own

Georgia requires state certification for septic tank contractors, pumpers, soil classifiers, and inspectors. Work must be done by a certified person or under their on-site supervision. New-system applications in this district also need a soil report from a Level III soil classifier. A Tennessee installer permit doesn't transfer, so whichever company takes your call, ask for its Georgia DPH certification before work starts; if a contractor working in Ringgold can't show Georgia credentials, that's a stop sign.

Where public sewer stops out here

Catoosa County's own economic development authority describes public sewer as a two-city affair (Ringgold and Fort Oglethorpe), with Ringgold's capacity capped at 4 million gallons a day by its arrangement with Chattanooga. Outside those city systems, unincorporated Catoosa runs on septic. In Walker County, the environmental health office in LaFayette handles septic inspection and permitting countywide. And the sewer that does exist is aging: county commissioners approved nearly $4 million in 2025 just to repair the system serving one 240-home Ringgold subdivision. Between them the two counties hold roughly 138,000 people and 59,000 housing units.

What's the same on both sides

Geology and weather don't check IDs at the state line: the same Ridge and Valley limestone, clay soils, and wet winters that stress Hamilton County systems stress these too. The field line page explains the mechanics. Costs track the same national ranges in the cost guide, and the buying-a-house advice on the inspection page applies doubly here, since Georgia requires an evaluation at loan closings.
