The short answer

Who handles sewer, water and septic in Cumming, GA?

The City of Cumming itself. Cumming Utilities runs the water and sewer inside a service area no other provider may serve, with a Lake Lanier water plant and a reclamation plant on Bethelview Road. Older homes can stay on septic, which Forsyth County Environmental Health permits. We repair the owner's side of all of it.

The Cumming story

The county seat that kept its own utility

Cumming started small. The town was laid out in 1833 on two 40-acre lots from the state land lottery, and its utility department was created along with the city by the General Assembly two years later.

It never handed the job off. Forsyth County built its own water and sewer department, yet the city still draws from Lake Lanier, pumps treated water through its own mains, and even sells raw water to the county.

The name on the mailbox can mislead you, though. Only about 8,500 people live inside the city, while the Cumming mailing area around it holds roughly 100,000 more. So the first question on any job out here is which utility actually sends the bill.

On the record

  • Cumming Utilities dates to 1835, when the General Assembly created it along with the City of Cumming.
  • Unincorporated areas with a Cumming mailing address hold about 100,000 people, and the Cumming census county division counted 118,538 in 2020.

Who owns what

Where the city's pipe ends and yours begins

Cumming's code draws the lines itself, so there is no county policy to look up.

Sewer or septic?

A sewered city that still has tanks

The city's rule for new building is simple: if sewer is available, connect, and no new tank. Homes that already had septic when the ordinance passed may keep it until the city or the county health department finds a health problem.

Cumming's hookup distance is tighter than the state's. Once the city sends official notice, an owner has 30 days to connect if a city sewer runs within 100 feet of the property line.

How to tell which one you have

  • A Cumming Utilities bill with sewer usage means the house is on city sewer.
  • A buried lid or riser in the yard, and no sewer line on the bill, points to a tank.
  • Forsyth County Environmental Health keeps the septic permit file for the address.

FAQ

Cumming sewer and septic questions

Straight answers, with the rule or record behind them. Still unsure? Call and ask the crew that digs.

(678) 863-5620

Is Cumming sewer run by the city or by Forsyth County?

By the city. Cumming Utilities serves the city's water and sewer service area, and city code says no other government or private utility may serve property inside it. A Cumming mailing address alone doesn't place a home inside that area.

Source: City of Cumming Code § 111-55 — Water and sewer service area

Do I have to connect to Cumming sewer if a line reaches my street?

If the city sends official notice and a public sewer sits within 100 feet of your property line, you have 30 days to connect at your own expense. That is half the distance the state rule uses.

Source: City of Cumming Code § 111-131 — Use of public sewers required

Can I keep my septic tank in Cumming?

Yes, if it was there before the ordinance and keeps working. The city allows existing septic until the city or Forsyth County's health department finds a public health problem. New construction must use sewer where it's available.

Source: City of Cumming Code § 111-132 — Private wastewater disposal

Who fixes a leak between the meter and my Cumming house?

You do. The city runs the service line to the property line and sets the meter there or within three feet of it; city code makes every leak on the customer's side of the meter the customer's responsibility. That line is one we repair.

Source: City of Cumming Code § 111-63 — Customer's responsibility and liability

Who owns a grinder pump in Cumming?

The homeowner. On the city's low pressure sewer streets, Cumming owns the shared force main in the right-of-way, while the owner buys, installs and maintains the pump and the line to it.

Source: Cumming Utilities — Grinder Pumps (Low Pressure Sewer)

Where do I get a septic permit in Cumming?

Forsyth County Environmental Health issues every septic permit in the county, city included. The office is at 2435 Freedom Parkway, Suite 2400 (770-781-6909). Cumming Utilities' own septic page points there too.

Source: Cumming Utilities — Septic

Why is my Cumming address on county water instead of city water?

Because the address and the city limits differ. Cumming city has about 8,500 residents, but the surrounding mailing area holds around 100,000 people. The service area is drawn by the mayor and council, not by ZIP code, so your bill is the reliable guide.
