Septic service in Forsyth County, Georgia
Forsyth County, anchored by Cumming, reached almost 282,000 residents in the year ending April 2025, adding 6,700 people at 2.4 percent, tied with Cherokee for the fastest growth in the Atlanta region (ARC estimates). It is also the easiest county in this corridor to plan a septic project in, for one unglamorous reason: it publishes its numbers. We connect Forsyth County homeowners with independent licensed septic contractors who work here weekly.
The county that publishes its fees
Two numbers organize most Forsyth septic paperwork, both on the environmental health fee schedule: $170 for a wastewater construction or repair permit, and $100 for a performance evaluation. The first covers building, replacing, or fixing a system. The second is Forsyth's quiet standout, the county-run health check most often used in home sales, covered in detail on the real estate septic inspection page and in the buying with septic guide. Neither Cherokee nor Hall publishes an equivalent schedule, which makes Forsyth the corridor's baseline for what county paperwork actually costs.
The county even encourages maintenance: the water and sewer department's septic tank pump-out rebate may be offered on qualifying pump-outs, by application after the service. What it pays and who qualifies change over time, so read the county page for the current terms. A county paying residents to pump on schedule says two things at once: a large share of its homes run on septic, and it would rather fund maintenance than clean up failures.
The office itself sits at 2435 Freedom Parkway, Suite 2400, in Cumming, phone 770-781-6909, with applications and requirements on its Land Use pages. Check the address before you drive: environmental health moved to Freedom Parkway, and the older 514 West Maple Street listing that still circulates in search results is closed.
Growth beyond the sewer lines
Sewer in Forsyth follows specific corridors rather than the county line, and even the City of Cumming's utility says plainly that sewer is available to a limited number of customers within its service area, gravity in some spots and grinder pumps in others. Everything outside those corridors treats wastewater on site, in the same slow-percolating Piedmont clay as the rest of the North Atlanta exurbs. For the county's construction pace, that means a steady stream of new septic installations, each starting with the site and soil evaluation through the environmental health office in Cumming under District 2 Public Health, with the septic permit ahead of the building permit per DPH Rules Chapter 511-3-1.
Forsyth also publishes what that evaluation paperwork must look like, on the same Land Use pages: the site plan shows the primary system and a secondary replacement area, tank included, with the reserve sized at the full 100 linear feet of line per bedroom, 300 feet for a three-bedroom home. And it sets the schedule expectation plainly: an application or review may take 20 business days or more, so file early rather than the week the builder needs the answer.
The office-by-office sequence, and how Forsyth's paperwork differs from its neighbors, is walked in the North Georgia septic permits guide, with city detail on the Cumming page. East of Lake Lanier, Hall County runs the same rules under the same health district with its own office quirks, worth knowing for property on that side of the water.
Verify your septic contractor in North Georgia
Georgia certifies septic installers and pumpers at the state level. Under DPH Rules Chapter 511-3-1, certification runs through the Department of Public Health: a certification exam scored out of 100 with 70 required to pass, company certification fees of $400 for installing and $400 for pumping, and continuing education each cycle (eight units for installers, six for pumpers). Every certification expires on February 28 of even-numbered years, so a current card is a recent card. The county environmental health office handles the other half: it evaluates your site and soil and issues the permit before any work starts. Ask for your contractor's DPH certification; a certified contractor expects the question.
Three questions to ask before you hire
- May I see your current DPH certification?
- Which of us files for the permit at the county environmental health office?
- Will the county inspect this work before it is covered up?

Frequently Asked Questions
What are the septic permit fees in Forsyth County?
Forsyth is the one county in this corridor that publishes its schedule: $170 for a wastewater construction or repair permit and $100 for a performance evaluation, through the environmental health office in Cumming under District 2 Public Health. Those two numbers cover most homeowner situations: fixing or building a system, and proving one works.
What is the $100 performance evaluation for?
It is the county-run check of a working system, most often ordered during a home sale when a lender asks for evidence the septic system functions. Because it comes from the same office that holds the system permit record, it is the cleanest answer to a lender request in Forsyth County.
Does Forsyth County help with the cost of pumping?
Forsyth County Water and Sewer runs a septic tank pump-out rebate program, and you may qualify by applying after the service. Amounts and eligibility change, so the county water and sewer page is the current word on what is offered and who is eligible. Check its terms before you book, then treat any rebate as a bonus on maintenance you should be doing anyway.
Is new construction in Forsyth County on sewer or septic?
Both, and the line runs lot by lot. Sewer follows specific corridors, and the City of Cumming itself notes sewer is available only to a limited number of customers in its service area. A meaningful share of the county that added 6,700 residents in the year ending April 2025 builds beyond the lines, where the septic permit comes before the building permit.
What it costs, and what happens after you send it
- What does septic work cost in Forsyth County?
- Published figures put it in five figures for the big jobs: a conventional drainfield replacement runs $3,000 to $15,000 (HomeGuide, 2026), a tank and drainfield replaced together run $5,000 to $12,000 (Angi, 2026), and a new conventional system installed runs $3,500 to $8,500 (HomeGuide, 2026). Those are national cost guides rather than a Georgia dataset, and North Georgia clay is the local factor they cannot see: tight soils are what push a system toward an alternative design and the upper end of any range. County permit fees are separate from what a contractor charges. Forsyth County publishes $170 for a wastewater construction or repair permit, and Cherokee and Hall publish their own. The Georgia cost guide prints the full table with every source.
