Who Pays for a Clogged Sewer Lateral in Roswell? Fulton County's Rule, Explained
Fulton County's rule puts the sewer lateral on the owner, even under the street. What the County will and will not do, and how to size the repair right.
Short Answer
The Owner Pays, All the Way to the Main
When a sewer backs up into a Roswell house, one of the first questions is whether the city or county will cover it. For the pipe between your house and the public sewer main, the answer is almost always no. Fulton County runs every public sewer main in Roswell. Its service lateral flyer says the owner is responsible if the lateral between the home and the property line clogs, leaks or breaks. That holds even if the blockage is inside a public road right-of-way or a sewer easement.
That surprises a lot of people, because the part under the street feels like public property. The rule is about who the pipe serves. Your lateral carries only your waste, so it is yours to keep working, just as your driveway is yours to repair.
This article covers what the County will and will not do, how costs usually break down, and how to avoid paying for a repair that is actually the County's.
Who Pays
Common Sewer Scenarios and Who Pays
Based on Fulton County's service lateral rules for Roswell and the rest of its sewer area.
| Situation | Who is responsible | Notes |
|---|---|---|
| Roots clog your lateral inside your yard | Owner | Clearing and any repair are private work |
| Your lateral breaks under the street right-of-way | Owner | The County or a County-approved contractor does the work in the right-of-way, at the owner's cost |
| Blockage in the County main | Fulton County | Several neighbors often back up at once |
| Cleanout needed in the right-of-way | Owner | Installed by the County or an approved contractor, fee paid first |
| Lateral outside the right-of-way or easement | Owner | The County will not repair it under any circumstances |
County's Role
What Fulton County Will Actually Do
The County's flyer lays out a narrow exception. Public Works will assist in removing a blockage in the right-of-way or easement only when all three conditions are met. First, there has to be a serious threat to public health if the problem is not resolved urgently. Second, a private plumbing professional hired by the owner has to be on site. Third, the owner has to sign a release holding the County harmless for any damage during that assistance.
For repairs and new cleanouts inside the right-of-way or a County easement, the County or a contractor it approves does the work, and the owner pays a stipulated fee before any work begins. Outside the right-of-way or easement, the County does not repair laterals at all.
If you suspect the main rather than your lateral, the North Fulton sewer after-hours emergency line listed on the County's flyer is 404-612-3061. A good sign that the main is the problem is several houses on the same street backing up at the same time.
What to Do Before You Pay for a Sewer Repair
These steps keep you from paying for the wrong fix, or the County's.
- Ask the neighbors. If several homes are backing up, call Fulton County first.
- Get the line cleared, then filmed. A camera run from your cleanout shows the pipe material, the defect and its distance from the house.
- Ask where the defect is. Inside your yard, under the right-of-way, or in the main. Each has a different path.
- Ask about a liner. Many defects in a round pipe can be lined without digging up the yard or the street.
- Check your policy. Look for a sewer backup endorsement and any service line coverage.
Keep the footage. It is useful for insurance, for a second opinion and for selling the house later.
Keeping the Cost Down
The cheapest sewer repair is the one sized to the actual defect. A root-filled joint five feet from the house is a very different job from a collapsed section under the street, and only a sewer camera inspection tells you which one you have. With the footage in hand, a single bad joint may be a small spot repair or a short point liner, while defects along most of the line point toward full lining or replacement. Our sewer line repair page lays out those options in order from smallest to largest.
The same Fulton County rules apply in Sandy Springs, where water comes from Atlanta but the sewer is Fulton's, so homeowners there face the same lateral responsibility even though their water bill looks different.
One more cost saver: if your house has no outside cleanout, adding one during a repair makes every future clearing faster and cleaner, and it gives the camera a better starting point.
Records
Documenting the Work for the Future
Whatever repair you choose, keep the camera footage, the invoice and a sketch showing where the cleanout and any repaired section sit. Future plumbers, insurers and buyers will all ask about the sewer line eventually, and good records turn a worrying question into a quick answer.
Records
Keep a File on Your Lateral
Because the lateral is yours, its history is worth keeping: dates of backups, invoices, and any camera footage with defect locations marked by distance. That record helps you spot a pattern, supports an insurance claim if a backup damages the house, and answers a buyer's questions when you sell. If the lateral is ever replaced, the new section falls under Georgia's state minimum plumbing code, adapted from the IPC, which sets the minimum slope a building sewer must have. A line that never met that slope is the one most likely to keep clogging.
Questions
Sewer Lateral Questions
Not as a routine service. The County's flyer says Public Works will help remove a blockage in the right-of-way or easement only when there is a serious threat to public health, a private plumber hired by the owner is present, and the owner signs a release. Even then, the lateral remains the owner's responsibility.
Usually not for wear, roots or age. A sewer backup endorsement may cover damage inside the house from a backup, and separate service line coverage may cover the pipe itself. Read your declarations page for both.
Then it is the County's to fix. That is one of the best reasons to camera the line before paying for a big repair. The footage, marked by distance from your cleanout, shows where your lateral ends and the main begins.
