Cumming Utilities runs the city's sewer, but nearby addresses may be on Forsyth County instead, and the drains and building sewer on your property are yours either way. A plumber can tell a fixture clog from a main line backup. Call the number on this page to be connected with a local plumber in Cumming.

Who handles sewer in Cumming?
Cumming, the Forsyth County seat and the county's only incorporated city, runs its own water and sewer utility, Cumming Utilities. Wastewater is treated at the Bethelview Road Advanced Water Reclamation Facility. To report a sewer spill, call the Distribution and Collection Division at (770) 781-2035; the main office line, (770) 781-2020, also works after hours. Not every address near Cumming is on the city system, though. Cumming Utilities publishes its service area only as a map, so homes outside city limits may be on Forsyth County Water & Sewer. Check your bill before calling about a street-side problem.
What causes clogs in Cumming homes?
Cumming grew from a small rural town into a fast-growing GA-400 commuter suburb near Lake Lanier. Census survey data put the median home at 1998, with about 17% built before 1980. Most drains are plastic, so clogs come from grease and food in kitchen lines, hair and soap in bath drains, and wipes in toilets. Wooded lots toward the lake and Sawnee Mountain add roots, which find joints in the building sewer as trees mature.
What can I try first?
- Plunge a single toilet or sink with the right plunger
- Clean out a tub stopper or bathroom pop-up
- Clear the disposal and flush it with cold water
Stop if more than one fixture is affected, water rises at another drain, a toilet gurgles when the washer drains, or the clog returns quickly. Those point to the main line. Skip chemical openers; they rarely clear a full blockage and leave a hazard in the trap. A rented drum machine can kink in the pipe if it's the wrong size, which can turn a cleaning into a repair.
Local note
Inside city limits, the City of Cumming's Planning & Zoning office issues plumbing permits, using a downloadable application, with inspections requested by phone. A routine clearing needs no permit. When you call, you'll be connected with an independent plumber who works in Cumming; tell them whether you're on city or county sewer, which fixture backed up first and whether the line has a history of clogs.
