What does septic installation require in Dacula, GA?
A new Dacula system needs a Level 3 soil report, a GNR Gwinnett application with lot sketch and floor plans, a 12-month construction permit and an inspection before cover. Much of Dacula lies in a groundwater recharge area, so placing the tank and field on suitable soil matters more than usual. We design, permit and install.↗↗

The Dacula story
Why Dacula's soil is also its water supply
Dacula's 2050 plan notes that a substantial portion of the city lies within a groundwater recharge area. In Georgia's Piedmont, the plan explains, most groundwater is stored in the soils above the rock, especially where those soils are thick. That is exactly the layer a drain field depends on.↗
Because of that, the state's recharge-area rules list septic tanks and drain fields alongside landfills and chemical storage as land uses to regulate, and the city's work program calls for enforcing septic tank ordinances in recharge areas. A good install here is one that treats effluent in the soil before it ever reaches the aquifer.↗
Dacula also falls inside the large water-supply watersheds of the Alcovy and Apalachee rivers. The plan says their intakes sit more than seven miles downstream, so no extra stream buffers apply under the state's Part 5 criteria, but the setbacks in Georgia's septic rules still do.↗
On the record
- A substantial portion of Dacula lies in a groundwater recharge area, where Georgia DNR rules regulate septic tanks and drain fields among other land uses.↗
- Dacula lies in the large water-supply watersheds of the Alcovy and Apalachee rivers; with intakes more than 7 miles downstream, no Part 5 buffers apply.↗
- Dacula's plan notes that in the Georgia Piedmont most groundwater is stored in overlying soils, particularly thicker soils.↗

More about Dacula
New builds and replacements in a young town
More than a third of Dacula's homes were built in 2010 or later, and building continues around Harbins Road and the Rowen district. New construction on lots without sewer starts with GNR before the lot is even created, since the county's environmental health involvement begins at the platting stage.↗↗
Replacement installs are the other half of the work: an older system in the Dacula East or South Alcovy areas that can no longer be repaired. There we plan around the existing house, drive and outbuildings, keep the old field's footprint in mind, and confirm no county sewer lies within 200 feet before committing to a new field.↗↗

FAQ
Dacula septic installation questions
Straight answers, with the rule or record behind them. Still unsure? Call and ask the crew that digs.
(678) 863-5620Is Dacula in a groundwater recharge area?
A substantial portion of it is, according to the city's 2050 plan. State rules for those areas regulate septic tanks and drain fields, and the city aims to enforce its septic ordinances there.
Who approves a new septic system in Dacula?
GNR Public Health's Gwinnett Environmental Health office. It needs a Level 3 soil report, a lot sketch and floor plans before issuing a construction permit.

Do I need a soil report for a brand-new system?
Yes. GNR has required a Level 3 soil report for all Gwinnett septic permits since February 7, 2022.
What does a new septic system cost in Georgia?

Do Dacula's river watersheds add setbacks?
The city's plan says the Alcovy and Apalachee intakes are over seven miles downstream, so no Part 5 buffers apply. Georgia's septic setbacks from wells and water still do.
I'm splitting land in Dacula. When does GNR get involved?
Before the lot exists. GNR's environmental health role begins when a lot is created, and its 2026 Gwinnett schedule charges $145 per lot to review a subdivision, exemption plat or individual lot for septic suitability.
