Who Pays for an Atlanta Sewer Lateral?
Updated 2026-10 · Atlanta, GA
The city’s rule, in its own words
The City of Atlanta’s ATL311 knowledge base defines the sewer service lateral as an extension of the house’s building sewer that connects the structure to the City sewer, and states that the maintenance and repair of the entire sewer service lateral is the property owner’s responsibility. Two words carry the weight: entire, and owner. There is no point at the curb or the property line where the city takes over. If the lateral crosses under the sidewalk and half the street to reach the main, all of that is yours.
What the city does own
The public sewer main, the larger pipe running under the street that all the laterals connect to, belongs to the City’s Department of Watershed Management. A blockage or collapse in the main is the city’s to fix. The practical question during any backup is therefore which side of the connection the problem is on.
How to tell which side it is
- Neighbours on the same main backing up at the same time: probably the main.
- Sewage overflowing from a manhole in the street: the main. Report it to ATL311.
- Backup only during or right after very heavy rain: possibly the main surcharging; see the storms guide.
- Only your house, in dry weather, with a history of slow drains: almost certainly your lateral.
- A camera inspection that reaches the main and finds it clear: your lateral.
When the problem is under the street
A lateral that has failed in the right of way is still the owner’s repair, but it is not an ordinary dig. Work in the public street needs the city involved, and the company doing it has to manage traffic and restore the road and sidewalk to the city’s standard. Expect that section to cost more per foot than the part under your lawn, and expect it to take longer to schedule. Lining from the cleanout can sometimes avoid opening the street at all, which is one of the better arguments for it.
Outside the city limits
Decatur and Brookhaven are on DeKalb County sewer; Brookhaven’s own guidance tells residents that homeowners are responsible for water and sewer pipes within their property. Sandy Springs is on Fulton County sewer, and Fulton County’s published guidance puts the lateral from the house to the property line on the owner even where the problem sits in a right of way or easement. The details differ, so ask the utility that sends your sewer bill.
Insurance
Standard homeowner’s policies commonly exclude wear, tree roots and deterioration of underground pipe, and many cover sewer backup damage inside the house only with an added endorsement. Some insurers and utilities also sell separate service-line cover. Whether any of that is worth it depends on your policy and your lateral, but for an owner of an untouched clay lateral under big oaks it is a reasonable question to ask an agent.

Common questions
The roots came from a city street tree. Does the city pay?
The ATL311 rule makes the lateral the owner’s to maintain and repair, and says nothing about where the roots came from. If you think a public tree caused damage, raise it with the city, but plan on the repair being yours.
Do I need the city’s permission to repair my lateral?
Building sewer work needs a plumbing permit, which the licensed company pulls. Work in the street needs the city involved as well.
