Forsyth County seat
Septic service in Cumming, Georgia
Cumming is a small city carrying a big county's paperwork: 7,318 residents at the 2020 census, seat of a Forsyth County that grew to almost 282,000 by April 2025, and home to the environmental health office that permits every septic system in the county. We connect homeowners in and around Cumming with independent licensed septic contractors who work this county weekly.
The city says it itself: sewer is limited
Cumming Utilities publishes its water and sewer service area and states that sewer is available to a limited number of customers, by gravity in some locations and grinder pump in others. That candor is useful: around the city, along the Highway 9, Highway 20, and Buford Dam Road corridors and out toward the Lake Lanier shoreline, the default is on-site treatment in slow-percolating Piedmont clay. Forsyth even nudges those homeowners to maintain their systems, with a $100 county pump-out rebate on qualifying pump-outs.
The work follows the county's two speeds. New subdivisions and custom builds beyond the sewer corridors start at new septic installation, evaluation first. Systems from Forsyth's earlier growth waves reach the drainfield replacement conversation, where the sourced ranges in the Georgia drainfield cost guide keep the quotes honest.
The corridor's only published fee schedule
Septic paperwork for Cumming addresses runs through the Forsyth County environmental health office in town, under District 2 Public Health, and the fee schedule is public: $170 for a wastewater construction or repair permit, $100 for a performance evaluation. Neither Cherokee nor Hall publishes an equivalent. The evaluation is Cumming's home-sale workhorse, covered on the real estate septic inspection page; the permit sequence itself is walked in the North Georgia septic permits guide, with the countywide picture on the Forsyth County page.
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
Is Cumming on city sewer?
Some of it. Cumming Utilities publishes a water and sewer service area map and says plainly that sewer is available to a limited number of customers, gravity in some locations and grinder pumps in others. The 7,318-person city at the 2020 census sits inside a county of nearly 282,000, and most of the Cumming-addressed area around the city treats wastewater on site.
What are the septic fees for a Cumming property?
Forsyth County publishes them, the only county in this corridor that does: $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.
What is the $100 performance evaluation used for in Cumming?
Mostly home sales. When a lender asks for evidence a septic system works, the county-run performance evaluation is the cleanest answer in Forsyth, because it comes from the office that holds the system permit record. Sellers can order it before listing and take the septic question off the table early.
I am building on acreage outside Cumming. What comes first?
The septic permit, before the building permit. The county environmental health office evaluates the site and soil, and that evaluation decides where the house, well, and field can sit on the lot. Booking it early is the cheapest schedule insurance a Forsyth build can buy.
