Doraville's sewer is DeKalb County's, but the drains and building sewer on each property are the owner's. With about 60% of homes built before 1980, older pipe is often behind repeat clogs. Call the number on this page to be connected with a local plumber in Doraville.

Doraville's housing and sewer
Doraville grew around the former General Motors assembly plant, and much of its housing dates from that era. Census survey data put the median home at 1975, with roughly 60% built before 1980. Ranch houses from the 1950s through the 1970s commonly have cast iron drains that scale and narrow inside, plus clay or cast iron yard lines where roots enter at joints. Newer townhomes near the old plant site have plastic pipe, where grease, wipes and hair are the usual problems.
The city doesn't run a water or sewer department; its utility links send water service to DeKalb County Watershed Management, which runs the county wastewater system. DeKalb's 24-hour emergency repair line, 770-270-6243, is for sewage spilling from manholes or into the street. If the backup is only coming up inside your home, the clog is almost always in your own plumbing.
Comparing your options
| Option | Use it when | Keep in mind |
|---|---|---|
| Cable machine | A sudden main line clog or root intrusion | Roots and grease can rebuild |
| Hydro jetting | Grease and scale coat the pipe | Inspect very old pipe first |
| Camera inspection | Clogs keep returning | Shows the cause, doesn't clear it |
In a house this age, a camera look after clearing is often worth the extra step. It shows whether the cast iron or clay still has years left or is cracking and offsetting at the joints, which tells you whether to budget for maintenance or a repair.
Signs to act on
- Toilets that drain slowly or gurgle when the tub empties
- A sink that fills with gray water from the next basin
- Rust flakes after a drain clears
- A sewer smell in the crawl space
- Drains that slow every summer
Timing notes
Roots grow most in warm weather, and older lines under mature trees often act up from late spring through summer. A slow drain can wait for a weekday visit; sewage in the house can't. If pipe has to be replaced, Doraville handles plumbing through its Trade Permit Application on the Cloudpermit portal, and every permit needs a notarized property-owner affidavit. When you call, you'll be connected with an independent plumber who works in Doraville.
