Alpharetta doesn't provide sewer; Fulton County Public Works does, and the county makes the owner responsible for the sewer lateral from the home to the property line, even when a blockage sits in the public right-of-way. Sewer line replacement in Alpharetta is new pipe for that private lateral, and with most homes built from 1980 to 1999, many of those lines are now 25 to 45 years old.

Alpharetta in brief
Alpharetta is an established north Fulton suburb and business hub, with Avalon, a revitalized downtown and mostly 1980s-2000s subdivisions. The median home was built in 1996 and only about 7.8% predate 1980, according to ACS 2019-2023 estimates; roughly 57% went up between 1980 and 1999. Laterals from those decades are mostly plastic, and they tend to fail from settled backfill, joints that shifted during construction, or later digging for pools, fences and irrigation rather than from age.
Fulton County's rule is worth knowing before anyone digs: the owner is responsible for the lateral from the home to the property line, even if a blockage is in the public right-of-way. For sewer trouble in the street, Fulton's North Fulton sewer customer service and after-hours line is 404-612-3061.
What to do now
- Stop using water so the line isn't pushed further.
- Ask whether neighbors are backing up. If they are, call Fulton County's North Fulton sewer line.
- Check the outdoor cleanout for standing water.
- Have a plumber clear the line and run a camera to the property line.
- Choose repair or replacement based on what the footage shows.
- Confirm the permit. Trade permits are applied for through Alpharetta's online Building/Trade/Tree portal, and inspections are requested through the city's Inspections Division at 678-297-6080.
What you see and what it usually means
| What you see | Usual cause |
|---|---|
| Backup returns after clearing | Belly, offset joint or crack |
| Standing water on camera in one stretch | Sag from settled backfill |
| Basement drain fills first | Restriction in the main lateral |
| Trouble began after yard work | Pipe damaged by digging |
Cost factors
- Distance from the house to the property line and depth of the pipe
- Trenchless where the slope holds, a trench where it has sagged
- Pools, patios, irrigation and landscaping over the route
- Any interior drain pipe replaced at the same time
- Permit and inspection through the City of Alpharetta
Because Fulton County's rule puts the whole run to the property line on you, ask the plumber to note on the camera footage where that line falls. Damage just past it may be the county's to fix.
