Doraville relies on DeKalb County for water and sewer rather than running its own system, so sewer line replacement in Doraville means new pipe for the private lateral between your house and DeKalb's sewer. With about 60% of the city's homes built before 1980, many of those laterals are original and worn along their full length. Call the number on this page to be connected with a local plumber in Doraville.
Why Doraville laterals wear out
Doraville's housing is among the older stock in north DeKalb. The median home dates to 1975 and roughly 60.6% were built before 1980, according to ACS 2019-2023 estimates. Many of those houses went up as the city grew around the former General Motors assembly plant, and their sewer laterals were usually clay or cast iron. After fifty-plus years, clay joints separate and invite roots, and cast iron rusts until the bottom of the pipe thins or cracks. The result is damage spread along the run rather than one tidy break.
The city's utilities menu sends water service to DeKalb County Watershed Management. Doraville's pages don't name a sewer provider directly, but DeKalb runs the county wastewater system, including the Pole Bridge and Snapfinger plants. Ask DeKalb where its part of the connection ends if the damage looks close to the street.
| Option | Best suited to | Limitation |
|---|---|---|
| Section repair | One failed spot in an otherwise solid line | Leaves old pipe on either side |
| Liner | Cracked but intact pipe with good slope | Won't fix sags or crushed pipe |
| Bursting | Reusing the existing path with new pipe | Needs pits at each end |
| Excavation | Collapsed, bellied or rerouted lines | Most restoration afterward |
Signs to watch for
- Frequent main-line clogs despite careful use
- Several drains slowing down together
- Bubbling in a toilet when the shower runs
- Bits of clay or rust showing up after a cleaning
Any one of these can come from a simple clog. Two or three together, in a house from the 1970s or earlier, usually mean the camera will find more than one failed section.
Permits and timing
Plumbing work goes on Doraville's Trade Permit Application, submitted online through Cloudpermit. Every Doraville permit needs a notarized property-owner affidavit, and payment by phone isn't accepted, so build a few days into the schedule for the paperwork. Planning + Community Development is at 2421 Van Fleet Circle. If the line is still working, line up the permit and the replacement before the next backup forces the issue. Ask the plumber, too, whether a new cleanout will be added near the foundation, since it makes future clearing and camera work far simpler.
