Coweta County Septic Permits: The 100-Foot Sewer Rule and Contacts

Sourced from the Coweta County Sewer Use Ordinance (rev. December 18, 2019), Coweta County Environmental Health, District 4 Public Health, and Ga. Comp. R. & Regs. 511-3-1 — last checked August 2026.

Who Issues Coweta County Septic Permits

Coweta is one of twelve counties in District 4 Public Health: Butts, Carroll, Coweta, Fayette, Heard, Henry, Lamar, Meriwether, Pike, Spalding, Troup and Upson.

Coweta County Environmental Health: 22 East Broad Street, Newnan, GA 30263 — (770) 683-7345
Hours: Monday to Friday, 8:00 a.m. to 5:00 p.m., closed 12:00 to 1:00
District 4 headquarters: 301 Main Street, LaGrange, GA 30240 — 706-845-4035

Why We Can’t List Coweta’s Fees

District 4 publishes no septic fee schedule — not for Coweta, and not for any of its twelve counties. Its application forms tell you to pay “the associated fee,” with the amount set at the county office.

Fee-setting authority in Georgia sits with each county board of health under O.C.G.A. § 31-3-4, not with the health district. That means twelve separate fee schedules inside District 4, and a figure from a neighboring county tells you nothing reliable about Coweta. We would rather publish no number than the wrong one. Call (770) 683-7345 and ask.

Have ready when you call: your parcel or tax ID, whether the property is on a private well or public water, and whether you need new construction, a repair, or a modification — each carries a different fee and different soil requirements.

Coweta’s Sewer Rule Is Stricter Than the State’s — and It Can Remove Your Choice

This is the most consequential thing to know about septic in Coweta County, and it is genuinely local. Most Georgia counties simply inherit the state floor. Coweta wrote its own, and it is tighter in three separate ways.

From the Coweta County Sewer Use Ordinance, revised December 18, 2019:

• §3.4 — mandatory connection where public sewer is within 100 feet of the property line. The state floor in 511-3-1 is 200 feet. Coweta halves it.
• §4.5 — no septic system is permitted “where a public sewer is accessible.” Note the word: accessible, not “within a set distance.” That is broader language than a pure measurement test.
• §4.6 — connection within 30 days of notice. Once the county notifies you, the clock is short.

What this means practically: in Coweta, whether you may install a septic system at all is a question to settle before you buy, design or budget anything. A parcel that would be straightforwardly septic-eligible one county over may not be eligible here. Ask Environmental Health, and ask the water and sewerage authority, and get the answer about your specific address rather than your general area.

Sewer Is Actively Expanding, Which Makes the Rule a Moving Target

The 100-foot test is not static, because the sewer network is growing. The Coweta County Water and Sewerage Authority has been expanding the Shenandoah water reclamation facility from 2 to 6 MGD, a roughly $60 million project targeted for completion in October 2026, alongside a comparable investment in a Chattahoochee intake upgrade. County population was 152,882 at the last count.

Put the ordinance and the expansion together and you get the actual Coweta question: a system you may legally install today could sit inside the 100-foot mandatory-connection radius in a few years. If you are weighing an engineered system against waiting for sewer, ask the authority directly whether a line is planned near your address within three to five years. That answer changes the math more than any fee figure would.

Replacing an Old Drain Field: There Is No Grandfather Clause

This is the fact that costs Georgia homeowners the most money, and almost nobody hears it up front.

Under Ga. Comp. R. & Regs. 511-3-1-.03(2)(c), repairs, replacements and additions to existing systems must be permitted and inspected. And 511-3-1-.03(1)(b) lets a failing residential system under 2,000 gallons per day avoid forced sewer connection only “if the repair or replacement of the system will meet the criteria set forth in the Manual” — today’s Manual, not the one in force when the system went in.

There is no reduced-criteria table for repairs. A field installed decades ago to the standards of its day gets re-sized to current standards. In practice that means a larger field, relocation to another part of the lot, or an alternative engineered system where conventional design will not fit.

In Coweta the grandfather question runs into the sewer question. If sewer has become available within 100 feet of your property line while your system aged, a failing system may not be repairable as of right — the ordinance points you at connection instead. Establish which situation you are in before you commission any work. See our Georgia septic repair cost breakdown, and the financial assistance routes that exist in Georgia.

Soil Reports, Not Perc Tests

Georgia does not use percolation tests. Permits are decided on a Level 3 soil classification report prepared by a Georgia DPH-certified soil classifier, who must carry $1,000,000 in liability insurance. If a contractor offers to run a perc test on your Coweta County lot, they are describing a procedure the state does not accept.

What a New Residential Application Requires

District 4’s forms are district-wide — one version naming all twelve counties. The New Residential and Residential Repair forms were last revised August 12, 2024; the commercial forms September 6, 2024.

A new residential application needs a lot sketch showing dimensions, the building footprint with setbacks, the road name, well locations on your property and on adjacent properties, driveway and paved surfaces, underground utilities, the plumbing stub-out, the proposed drain field location, easements, floodplain, and any detached structures.

Two clocks. The county board of health “shall approve or disapprove such application within twenty days after the receipt of a completed application” (511-3-1-.03) — and the words that matter are completed application. An issued permit expires 12 months from issue. Notify Environmental Health before final cover; an inspection they were not given the chance to make is a system they will not sign off.

Statewide Rules That Apply in Coweta

None of this is local to Coweta — it comes from DPH Chapter 511-3-1, covered in full on our Georgia septic regulations page. These are simply the provisions Coweta applicants hit most often.

• A permit is required before you “begin the physical development of a lot or structure.”
• Only DPH-certified contractors may perform the work.
• Minimum tank size 1,000 gallons; two-compartment with an effluent filter for anything installed after February 20, 2000.
• Setbacks: 50 feet tank to well, 100 feet absorption field to well, and not less than 50 feet from the normal water level of any impoundment, stream or ponded wetland.
• The state mandates sewer connection where public or community sewer is available within 200 feet of the property line. Coweta’s own ordinance is stricter at 100 feet, and the stricter local rule is the one that governs.
• Georgia requires no point-of-sale septic inspection anywhere in the state. Nobody will make you look at the system on a Coweta County house you are buying. Look anyway.

What We Could Not Confirm

Where Coweta Sits

Newnan anchors a county sitting directly on the I-85 corridor between Atlanta and the Alabama line, and it is taking growth from both directions. That growth is why the sewer network is expanding and why the 100-foot rule keeps catching up with properties that were rural a decade ago. For how Coweta compares with the five separate health authorities operating across metro Atlanta, see our Atlanta metro septic guide. Its District 4 neighbors Fayette and Pike take a very different approach, with no county sewer utility at all in Pike’s case.
