Cumming Utilities, the city's own water and sewer utility, pumps Lake Lanier water to its treatment plant on Dahlonega Highway, so homes on its system have no pump of their own, and we found no count of private wells. Some addresses near Cumming may be on Forsyth County water instead. A plumber can test a well if you have one, or find the cause of weak water on public supply. Call the number on this page to be connected with a local plumber in Cumming.

Who supplies water in and around Cumming?
Inside the city, Cumming Utilities does. It pumps raw water from Lake Lanier to its Potable Water Production Facility at 935 Dahlonega Highway, and bills at City Hall. Its service area map is published only as a PDF, so our fact sheet doesn't say which nearby addresses fall to Cumming and which to Forsyth County. Your bill settles it. Either way, a public water customer has no pump; a capped casing and a pressure tank would mean a private well.
Why would my water pressure drop?
Cumming grew from a small rural town into a fast-growing GA-400 suburb near Lake Lanier, and the median home dates to 1998. Regulators from that era are often near the end of their life, and a failing one is the most common reason an entire house loses pressure. Leaks on the line from the meter, valves left partly closed and debris in fixtures after main work are next on the list.
If only one fixture is weak, the cause is local: a clogged aerator, a worn cartridge or a stop valve under the sink. If every fixture is weak, look to the regulator or the service line. If neighbors have the same drop, call the utility first. Hot water only? That points to the water heater, which is a different repair entirely. Sorting this out first makes the plumber's visit faster.
What should I do if I think there's a leak?
Close every fixture and watch the meter for a few minutes. If it moves, water is escaping past the meter. Cumming Utilities takes reports of water leaks and sewer spills at (770) 781-2035, and its main office, including after hours, is (770) 781-2020. If the leak is on your property, a plumber finds and fixes it.
