The short answer

Is Locust Grove on sewer or septic?

Both. Locust Grove runs its own sewer, treated at the city's Indian Creek plant since 2005, and newer subdivisions tie into it. Rural RA-zoned acreage and Luella-area addresses can keep septic tanks permitted through District 4 Public Health. Atlanta Water & Sewage Solutions repairs city laterals, water lines and septic systems here.

Housing era

A town whose median house is barely twenty years old

In 1900 Locust Grove counted 254 residents. The General Assembly had incorporated it in 1893, naming it for a stand of locust trees near the first town site, and a Norfolk Southern line still runs beside Highway 42. Today the town meets I-75 at Exit 212, Tanger Outlet Center has been open since the fall of 1994, and the rooftops keep coming.

The Census numbers show how recent the housing is. Half of the city's 3,651 homes were built in 2005 or later. Another 442 went up in 2020 or after, while only 83 date from before 1940. For underground work that is good news and a warning: most pipe is young PVC, but young pipe laid in fresh fill can settle, and builder-grade connections are only as good as the day they were made.

Sewer or septic?

Sewer inside the grid, tanks on the acreage

Locust Grove's code draws the line by distance and gravity. If a building sits within 250 feet of a public sewer it can drain to without a pump, the city can order a connection, and the owner has 60 days after notice to make it. Where no sewer is available under that test, the building sewer goes to a private system that meets Chapter 13.20.

Zoning keeps room for tanks. The RA residential-agricultural district lists septic as permitted on a 1-acre lot with city water, 1.25 acres with a private well, and 2 acres for a new subdivision. Across the county, HCWA reports that only about 43% of its water customers are also sewer customers, which tells you how common tanks still are just outside town.

How to tell which one you have

  • Your Locust Grove bill shows a sewer charge figured on 100% of your water use
  • A green round lid marked SEWER near the front of the lot is a city-standard cleanout box
  • No sewer line on the bill and a concrete lid in the yard means a tank

The Locust Grove story

Two kinds of service call in one ZIP code

On a subdivision street off Bill Gardner Parkway, the typical call is a backup or a wet spot between the house and the curb. The city built its Indian Creek plant in 2005 to handle that growth, and every one of those homes drains toward it through a lateral the owner is responsible for up to the property line.

A few miles out, on a farm road with a Locust Grove mailing address, the same symptom usually means a septic tank or drain field. Those systems answer to District 4 Public Health's Henry County office in McDonough, not to City Hall. The first thing we establish on any call here is which of the two you have, because it changes the permit, the fix and who you call about it.

On the record

  • The Georgia General Assembly incorporated Locust Grove in 1893; it is named for a grove of locust trees near the original town site.
  • Locust Grove sits on I-75 at Exit 212, Bill Gardner Parkway, and Tanger Outlet Center opened there in 1994.
  • 442 Locust Grove housing units were built in 2020 or later; 83 date from 1939 or earlier.
  • The median Locust Grove home was built in 2005.

(678) 863-5620

Where does Locust Grove's sewage get treated?

At the city's own Indian Creek Water Pollution Control Plant, which opened on December 1, 2005 and treats 1.5 million gallons a day. It replaced the older plants the city ran before the growth years. Homes on septic, of course, treat their own wastewater on the lot.

Can the city make me hook up to sewer?

Yes, if you are inside the limits and within 250 feet of a public sewer your building can drain to by gravity. The code gives you 60 days after official notice to connect at your own cost. Outside that reach, a private system is allowed under Chapter 13.20.

Source: Locust Grove, GA Code of Ordinances § 13.12.060 (Municode)

Is septic allowed on my Locust Grove lot?

It depends on zoning and size. The RA district permits septic on 1 acre with city water or 1.25 acres with a well, and 2 acres for a new subdivision. Any system also needs District 4 approval, and the city adds its own consent step.

Source: Locust Grove, GA Code of Ordinances § 17.04.047 (Municode)

Who issues septic permits for Locust Grove addresses?

Not the city. Septic paperwork for a Locust Grove address goes up the interstate to McDonough, where District 4 keeps its Henry environmental health staff at 137 Henry Parkway. That office permits, inspects and takes complaints about on-site systems, and it uses separate forms for new residential systems and for repairs.

How is my Locust Grove sewer charge calculated?

The city bills sewer on 100% of the water that runs through your meter, under household rates effective April 2025. That means a leak on your side of the meter raises both the water and the sewer lines of the bill.

Source: City of Locust Grove - City Brochure (April 2025)

Where does Locust Grove get its drinking water?

Mostly from its own sources: a spring on Davis Lake Road, two wells at Warren Holder Park and a well on Strong Rock Parkway. The Henry County Water Authority is connected as a backup.

Source: City of Locust Grove - Public Works

Who do I call about a water main break at night?

The city's after-hours utility emergency line, 770-692-2350, where you leave a message for staff. A leak on your side of the meter is yours to repair, and that is work we do.
