When do I have to connect to sewer in Walnut Grove, GA?
Walnut Grove's code requires owners to connect when a city sewer is within 300 feet of the property line, a wider reach than Georgia's 200-foot rule. Once sewer is available, the connection is due in 60 days and the septic tank must be abandoned. The owner pays for the line, including any road bore.↗↗

Permits · City of Walnut Grove (sewer superintendent)
What Chapter 42 asks of a new connection
- 01
Apply for a building sewer permit on the city's form. There are three classes: residential, commercial and industrial, each with a permit and inspection fee paid at filing.↗
- 02
Plan for the owner to carry every cost, including boring under the entire road and restoring open cuts across city streets, county roads and state highways.↗
- 03
Reusing an old building sewer? It has to pass the superintendent's testing first, which can include pressure tests, a mandrel, video inspection or smart pigging at the applicant's expense.↗
- 04
Notify the superintendent when the line is ready. The connection is made under city supervision, and the excavation stays open until the inspection is documented.↗
- 05
Within 60 days of sewer becoming available, abandon the septic tank: cleaned of sludge and filled with clean gravel, dirt or other suitable material.↗
Sewer or septic?
A sewer town with a lot of tanks
The city treats its wastewater at a small plant on Forrester Cemetery Road that land-applies up to 0.05 million gallons a day under state permit GAJ040019. That limit is why sewer hasn't simply spread across town.↗
Growth is pushing on it. GEFA lent the city $2.44 million in late 2024 for a 0.10 MGD plant and a bigger application field, and the comprehensive plan sketches a Phase 3 that would add 1,000,000 gallons a day through land application and direct discharge.↗↗
How to tell which one you have
- Ask the city whether a main or planned main runs within 300 feet
- Look for a sewer charge on your city bill
- Find the tank lid; if there's one, you're not connected

The Walnut Grove story
Grade, gravity and the grinder option
The code prefers a building sewer that arrives below the basement floor so gravity does the work. On the rolling lots around the SR-81 and SR-138 crossroads that isn't always possible. Where the house sits below the main, Walnut Grove allows an ejector station: a tank near the foundation with a submersible grinder pump pushing wastewater into the city's gravity line, sized to health department rules.↗
We shoot elevations at the house and at the main before quoting, so you know on day one whether you're buying a gravity line or a pump.

More about Walnut Grove
Shops and new subdivisions
Commercial and industrial connections get their own permit classes, and any industry producing process waste must meet EPA and EPD rules before it connects. Capacity is the bigger constraint: the current expansion covers roughly 24,000 gallons a day of business use, so ask the city about availability before signing a lease that assumes sewer.↗↗
When we abandon a tank as part of a conversion, the pumping is done by us: we're on Georgia DPH's approved pumper list for Walton County.↗

Can I keep using my old sewer pipe for a new house?

Can I build a new septic system instead?
Inside the city, not on a lot under one acre, and not once sewer is available within the connection distance.

Is there room at the plant for my connection?
That's the city's call. The permitted plant is small, and the current expansion covers about 155 more homes, so confirm availability early.
