Avondale Estates doesn't own its sewer system; DeKalb County Watershed Management owns and operates the public pipes, so a sewer line replacement here covers the private lateral from your house to DeKalb's sewer. Because much of the city was built in the 1950s or earlier, original laterals that have cracked and filled with roots are a common reason for the job. Call the number on this page to be connected with a local plumber in Avondale Estates.
Avondale Estates: old homes, county sewer
George Francis Willis laid out Avondale Estates as a planned community in 1924, and its housing shows it. The median home dates to 1966, about 54.8% were built before 1980, roughly 25.7% went up in the 1950s and 12.7% in 1939 or earlier, according to ACS 2019-2023 estimates. Laterals from those decades were typically clay or cast iron, and many are still in service.
The public side is not the city's to fix. Avondale Estates says DeKalb County Watershed Management owns and operates the water and sewer infrastructure in town, that the city has no authority to maintain, repair or replace it, and that only DWM or its contractors work on those assets. The pipe running from your foundation toward the street is a different matter: it is private, and replacing it is a job for a plumber. Where exactly DeKalb's portion begins isn't spelled out in what we found, so ask DWM if the damage sits near the street.
| Approach | When it fits | What to weigh |
|---|---|---|
| Point repair | One cracked or root-choked section in otherwise sound pipe | The rest of a 60-year-old line stays in place |
| Cured-in-place lining | Pipe is cracked but round and still sloped | Cannot correct a sag or rebuild a collapse |
| Pipe bursting | Old route is usable and pits can be dug at both ends | Needs working room near the house and the tie-in |
| Full excavation | Bellied, collapsed or rerouted line | Most disturbance to lawn, walks and plantings |
Warning signs
- A main-line clog that comes back within months of clearing
- The basement drain or lowest tub filling when the washer empties
- Sewer odor near the outdoor cleanout
- A strip of lawn that stays soft or extra green over the line
Timing and permits
Plan the permit before the dig. Avondale Estates handles building permits and inspections through Community Core, and the city requires separate trade permits for plumbing regardless of the job's value. Planning and Development is at City Hall, 21 North Avondale Plaza. If you know the line is failing, a scheduled replacement during a dry stretch is easier on a yard than an emergency dig after a backup.
