Septic installation in Locust Grove, GA
A new septic system in Locust Grove needs a lot big enough for its zoning, the city's written consent inside the limits, and a District 4 new-system permit.

The Locust Grove story
Why Locust Grove adds its own step for new tanks
Septic permits are normally a health department matter. Locust Grove adds a municipal layer. The city code says no one may build a private sewage system without applying to the city, paying an inspection fee and getting written consent from the mayor and council.↗
The consent comes with a promise: you sign an agreement that when city sewer reaches the property, you or whoever owns it next will connect and pay the tap fees. For a house on acreage south of town that day may never come, but the code binds heirs, buyers and successors too, so a purchaser should know about it.↗
Part of the reason is water. The city and HCWA review development in three protected water-supply watersheds here, the Towaliga River, Indian Creek and Tussahaw Creek; a field placed carelessly there affects water other people drink.↗

The order we file things in
- 01
Confirm the zoning and lot size, and whether a city sewer is within reach; if it is, the city will expect a connection instead.↗
- 02
District 4 residential new application: a lot sketch showing dimensions, the house, setbacks, wells on your lot and neighbors', paved areas, buried utilities, the plumbing stub-out, the proposed drain field, easements and flood plain.↗
- 03
The same form asks bedrooms, garbage disposal, water source, foundation type and whether a basement needs a lift pump.↗
- 04
Inside the city, file the private-system application and get written consent; the city's requirements sit on top of the health officer's, not in place of them.↗
- 05
Install, then call both inspectors. District 4 requires a final inspection before final cover, and the city's superintendent inspects within 48 hours of notice, before anything underground is buried.↗
- 06
A District 4 permit expires 12 months after it is issued, so we schedule the install inside that window.↗

Sizing the tank for the house
Georgia's homeowner guide, which District 4 hosts, sets the basics. Tanks installed since February 20, 2000 need two compartments and an effluent filter. A 1,000-gallon tank is the minimum and serves three or four bedrooms, and a garbage disposal adds 50% to the required size.↗
District 4's new-system form lists conventional gravel, chamber and EZ-Flow as its preferred field types. On a lot that slopes toward a creek, the layout may need a pump tank, which under the same guide carries reserve storage and an audible high-water alarm.↗↗

Homes versus commercial buildings
Most new systems here serve one house. District 4 keeps a separate commercial new-system application, and commercial parcels in the city's watershed district need more land on septic than on sewer, so a shop or church outside the sewer area is designed from the lot outward.↗
FAQ
Locust Grove septic installation questions
Straight answers, with the rule or record behind them. Still unsure? Call and ask the crew that digs.
(678) 863-5620How big does my lot need to be for septic in Locust Grove?

Do I need the city's permission, or just the health department's?
Inside the limits you need both. The city requires an application, an inspection fee and written consent from the mayor and council, and District 4 issues the septic permit itself. Outside the limits, District 4 alone.
Source: Locust Grove, GA Code of Ordinances § 13.20.020 (Municode)
What goes on the District 4 site sketch?
Lot dimensions, the house, setbacks and road name, every well including the neighbors', paved areas, buried utilities, the plumbing stub-out, the proposed field, easements, flood plain and any detached buildings. We prepare it from a site visit.

What size tank will my new house need?
The state guide sets 1,000 gallons as the minimum, good for three or four bedrooms, and requires two compartments with an effluent filter. Add a garbage disposal and the tank must be 50% larger.
Source: Georgia DPH - A Homeowner's Guide to On-Site Sewage Management Systems (hosted by District 4)
Will I have to switch to sewer later?
Possibly. The consent agreement commits the owner, and later owners, to connect and pay tap fees if city sewer becomes available, and the tank must then be abandoned and filled.
Source: Locust Grove, GA Code of Ordinances § 13.20.020 (Municode)
How long is a District 4 permit good for?
Twelve months from issue. The system also has to pass a final inspection before final cover, so plan the house schedule around it.

What does a new septic system cost near Locust Grove?
Angi's Atlanta data puts a conventional system at $3,000 to $8,000 and a drain field alone at $5,000 to $12,000. Soil, rock and pump needs move the number. We quote your lot for free after walking it.
