Brookhaven doesn't run a sewer system; DeKalb County's Department of Watershed Management owns the mains and service laterals, and homeowners are responsible for the plumbing on their own property. A plumber repairs the private drain piping, while problems in DeKalb's part go to the county. Call the number on this page to be connected with a local plumber in Brookhaven.
Who fixes what in Brookhaven?
The City of Brookhaven is unusually direct about this. Its public works page says DeKalb County Watershed Management owns and operates the sanitary sewer system in the city, including manholes, pipes and service laterals, and that the city itself cannot maintain, repair or replace those assets. Only DeKalb or its contractors may work on them. The same page reminds homeowners that the systems on their own property are theirs. In practice, that means the drain piping on your lot is a job for a private plumber, and anything on DeKalb's side is a call to the county at 770.270.6243, the number Brookhaven lists for sewer spills.
The exact handoff point isn't spelled out on the city page, so if a repair looks like it will reach toward the street, have the plumber confirm with DeKalb before digging.
Are older Brookhaven homes more likely to have sewer problems?
Generally, yes. The citywide median home dates to about 1994, but roughly 30% were built before 1980, including close to 9% from the 1950s. Neighborhoods like Historic Brookhaven and Lynwood Park have many of those older houses, where building drains may be cast iron or clay. Cast iron corrodes and scales from the inside; clay joints loosen and let roots in. Newer infill and townhomes mostly use PVC, which fails in different ways, such as sags or joints disturbed by nearby construction.
What does a repair visit look like?
A plumber usually clears the blockage from a cleanout, then runs a camera to see the pipe material, the defect and how far from the house it sits. That footage also answers the ownership question, since it shows whether the trouble is on your lot or beyond it. Brookhaven's permit FAQ notes that changes to plumbing lines require a permit, and permits and inspections are handled through the city's online portal.
One local note
Because DeKalb owns so much of the system here, a backup affecting several houses on the same street is worth reporting to the county first. When only your home is affected, start with a plumber and a camera.
