Who provides sewer and water in Alpharetta, GA, and what do I own?
Fulton County's Department of Public Works supplies Alpharetta's water and sewer and bills both; the city does not. The county's part stops at the water meter and, for sewer, at the property line. The water pipe and sewer lateral on your lot are the owner's, and those are the lines we repair and replace.↗↗

The Alpharetta story
From county seat to suburb
Alpharetta is older than it looks. It was chartered on December 11, 1858, after spending its first months as the town of Milton, and it served as the seat of Milton County until 1931, when Milton merged into Fulton County to avoid bankruptcy during the Depression.↗
The houses, though, are mostly new. The city now counts about 67,000 residents, and its best-known places, Avalon (opened in 2014), North Point Mall and the Windward business area, are all modern. So is most of the plumbing beneath them.↗↗

Median year homes were built
1996
Typical house here is about 30 years old — and so is its original sewer or septic line.

Housing era
One-third of the city, one decade
The American Community Survey counts 9,081 Alpharetta homes built in the 1990s, about 35 percent of the total and far more than any other decade. Most are single-family houses in subdivisions laid out in a few years, with laterals and water service lines installed by the same builders at the same time.↗
Those private lines are now thirty years old. That is young for a sewer, but it is exactly when landscaping trees planted at move-in reach the pipe, when settled backfill leaves bellies that hold water, and when cleanouts buried by later patios become hard to find.
More about Alpharetta
Where Alpharetta's sewage goes
Wastewater from Alpharetta flows to Fulton County's Big Creek Water Reclamation Facility on Marietta Highway in Roswell, which serves about 70 square miles including Roswell, Alpharetta and parts of Johns Creek and Milton. The first plant there, built in 1971, treated 750,000 gallons a day.↗
In 2024 the county finished a $350 million rebuild that raised capacity to 32 million gallons a day and made Big Creek the second-largest flat-membrane plant in the country. That investment ends at the public main. The service line from your house still depends on you.↗

More about Alpharetta
What Fulton charges at the meter
If a remodel or addition needs a bigger water service, the county side has published prices. Fulton's 2026 North Fulton schedule lists a new 3/4-inch meter installation at $4,200, a $1,575 system capacity fee plus $2,625 for the meter, and a road bore for a small meter at $708 across two lanes.↗
Those fees cover only the county's work. The new private line from the meter to the house, and any sewer lateral changes, are separate, and that is the part we scope and build.

Sewer or septic?
Alpharetta is a sewer town
Septic is common a few miles north in Milton, but not here. If you are buying on the Milton line, check the bill: a Fulton sewer charge means the house is connected.↗

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

Is a sewer clog under the sidewalk Fulton County's problem?
Usually not. Fulton's flyer makes the owner responsible for the lateral from the building to the property line even when the blockage is in the right-of-way.

Fulton County's North Fulton water emergency line, 770-640-3040. Sewer concerns go to 404-612-3061 around the clock.
Where does Alpharetta's wastewater get treated?
At Fulton County's Big Creek Water Reclamation Facility in Roswell, rebuilt in 2024 to treat 32 million gallons a day.
How much is a new water meter in Alpharetta?
Fulton's 2026 schedule lists $4,200 for a new 3/4-inch meter installation, including the $1,575 capacity fee; the private line to the house is extra.
My house is from the 1990s. Is the sewer line really old enough to fail?
It can be. About 35 percent of Alpharetta homes date from the 1990s, and thirty-year-old laterals commonly show root entry and settled sections on camera.
