How do you get a septic system repaired in Suwanee, GA?
Suwanee has no septic office of its own. Repairs to the tanks the city says still serve many historic-area homes are permitted by GNR Public Health's Gwinnett Environmental Health office in Lawrenceville, which requires a Level 3 soil report first and aims to review within ten working days. We handle that paperwork and the repair.↗↗↗

The Suwanee story
Tanks in the oldest part of a new-looking city
Drive through Suwanee's subdivisions and it's easy to assume every house is on sewer. The city's public works pages say otherwise: many homes in the historic area still have septic systems, on the streets that were here long before the subdivisions.↗
Those systems are older than the rules that now govern repairs. A failure today means a soil classifier's report, a permit from the county health office, and sometimes an engineered plan before anyone digs.↗↗
On the record
- The City of Suwanee states that many homes in its historic area have septic systems.↗
Sewer or septic?
Is your Suwanee house on a tank?
The city's own test is the Gwinnett water bill. A zero in the sewer amount line usually means a tank. Gwinnett adds that its GIS Data Browser can show a septic sketch and past repair permits where they exist.↗↗
How to tell which one you have
- Look for a buried lid or riser in the yard.
- Call Gwinnett Environmental Health for the permit sketch on file.

More about Suwanee
Additions and remodels on a Suwanee septic lot
Suwanee's building code ties the city's permit to the county's approval. Plans for sewage disposal must clear the county board of health before the city issues a building permit, and the finished system must pass before occupancy.↗
In practice that means a bedroom addition or a new pool on a tank lot starts with a septic review, not with the framing crew. If the old field sits where the addition goes, the repair and the remodel get designed together.↗

Do I need a soil report to fix my Suwanee septic?
Yes. Since February 7, 2022, GNR has required a Level 3 soil report for every septic permit, repairs included. An approved report already on file for your lot can be reused.
How long does a GNR septic repair permit take?
GNR asks for about ten working days to review the application and visit the site. Missing items or a required engineered plan can stretch that.

Can I add on to a Suwanee house that's on septic?
Only after the county health office approves the sewage disposal plan. Suwanee's code holds building permits until that approval and withholds the certificate of occupancy until the system passes.

How much does the Gwinnett septic permit cost?
GNR's 2026 schedule lists $275 for a residential site evaluation, permit and first inspection, or $400 when the permit follows a complaint. Soil classifier fees are separate.

Will I be forced onto sewer instead of repairing?
Only if public sewer is available. Georgia's rule sends a failed system to sewer immediately when a line is within 200 feet of the property line or in the abutting right-of-way; otherwise a permitted repair keeps the tank in service.

Where exactly is my septic tank?
Gwinnett Environmental Health has records for systems installed since 1959 and can send a sketch of the approximate location. Call 770-963-5132 with your address.
