Pike County Septic Permits: Requirements, Lot Sizes, and Contacts

Sourced from the Pike County zoning ordinance (Article 19, Groundwater Recharge Area Protection), the Pike County Water & Sewerage Authority, District 4 Public Health, Ga. Comp. R. & Regs. 511-3-1, and the 2020 Census — last checked August 2026.

In Pike County, Septic Isn’t a Choice

Most county septic guides open by telling you to check whether sewer is available first. In Pike County there is nothing to check. The Pike County Water & Sewerage Authority — the body with “sewerage” in its own name — states that “we don’t actually provide the sewerage services ourselves at this time.” The 2020 Census classified the county as 99.7 percent rural.

That has one practical consequence worth understanding before you buy land here: the soil is the permit. In a sewered county a marginal lot can still be built on. In Pike County, if the soil will not take an onsite system at the size the ordinance requires, the lot is not buildable at all. Everything else on this page follows from that.

Who Issues the Permit

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

Pike County Environmental Health: 541 Griffin Street, Zebulon, GA 30295 — (770) 567-8972
Environmental Health hours: Monday to Friday, 8:00 a.m. to 4:30 p.m.
District 4 headquarters: 301 Main Street, LaGrange, GA 30240 — 706-845-4035

One small thing that catches people: Environmental Health closes at 4:30, half an hour before the clinic side of the same building. If you are dropping off a site plan at the end of the day, that half hour matters.

Why We Can’t List Pike’s Fees

District 4 publishes no septic fee schedule — not for Pike, and not for any of its twelve counties. Its application forms simply instruct you to pay “the associated fee,” with the amount determined 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. There are twelve separate fee schedules inside District 4, which means a figure published by Fayette or charged in Henry tells you nothing reliable about Pike. We would rather publish no number than the wrong one. Call (770) 567-8972 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.

The Lot Size Math Nobody Explains

This is where Pike County genuinely differs from its neighbors, and it is the section worth reading twice.

Start with zoning. In the A-R (Agricultural-Residential) district the minimum lot is 5 acres. For new major subdivisions the minimum is 10 acres per lot.

Then apply the overlay. Article 19 of the zoning ordinance establishes a Groundwater Recharge Area Protection district. Under standard S-3, a lot served by an onsite system must exceed the base minimum, scaled to how vulnerable the recharge area beneath it is:

• High pollution susceptibility — 150% of the subdivision minimum lot size
• Medium — 125%
• Low — 110%

Run that against a 5-acre base in a high-susceptibility area and the minimum becomes 7.5 acres. On a 10-acre major-subdivision lot in the same area, 15.

The susceptibility mapping comes from Georgia DNR’s Hydrologic Atlas 18 (1989) and the DRASTIC mapping in Atlas 20. These are state maps the county adopted by reference — not something a seller, a listing agent, or a plat is likely to have checked. Before you make an offer on land in Pike County, ask Environmental Health which susceptibility category the parcel falls in. It is the difference between a buildable 5 acres and an unbuildable 5 acres.

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.

If your system is failing, you cannot simply put back what was there. 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 drain field installed in 1980 to 1980 standards gets re-sized to current standards. In practice that means one of three outcomes: a larger field than you had, relocation to a different part of the lot, or an alternative engineered system if conventional design will not fit.

In Pike County — no sewer to fall back on, and lot area already committed by the recharge overlay — relocation is the option to check earliest. Find out where your replacement area is before you need it — and see what the work typically runs in our Georgia septic repair cost breakdown. If cost is the obstacle, check the Georgia septic financial assistance options first.

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 Pike 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 to hold on to. 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 there 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 do is a system they will not sign off.

Statewide Rules That Apply in Pike

Nothing below is a Pike County invention — it comes from DPH Chapter 511-3-1, covered in full on our Georgia septic regulations page. It is repeated here because these are the provisions Pike applicants actually run into.

• A permit is required before you “begin the physical development of a lot or structure” — not before you finish it.
• 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.
• Sewer connection is mandated where public or community sewer is available within 200 feet of the property line — a rule with essentially nothing to bite on in Pike County today.
• Georgia requires no point-of-sale septic inspection anywhere in the state. If you are buying here, nobody will make you look at the system. Look anyway.

Where Pike Sits

Pike County lies entirely within the Upper Flint sub-basin, and it absorbs growth pushing south out of Fayette and Coweta. What makes it unusual is that it has kept the lot sizes that force large-lot septic rather than relaxing them to take that growth. For a homeowner that cuts both ways: your neighbors will not be close, and there is no sewer line coming to rescue a marginal lot.

For how Pike compares with the metro counties to its north — four separate health authorities, four fee schedules, four sets of local practice — see our Atlanta metro septic guide.
