Kennesaw doesn't run its own water or sewer; Cobb County Water System serves the city, so sewer line replacement in Kennesaw means new pipe for the private lateral between your house and Cobb's sewer. Most Kennesaw homes were built in the 1990s and 2000s, so the trigger is often a sagged or damaged pipe rather than one worn out by age.

Kennesaw basics
Kennesaw is a Cobb County city with Civil War and railroad history, home to Kennesaw State University and next to Kennesaw Mountain. Its housing is relatively young: the median home dates to 1998, and about 11% predate 1980, according to ACS 2019-2023 estimates. Plastic laterals from those years don't corrode, but settled backfill can leave a belly that collects waste, and digging for fences, decks or irrigation can crack a line. Cobb County Water System handles the public sewer, with an emergency line of 770-419-6201 for sewer backups.
What to do now
- Cut water use to a minimum.
- Ask nearby neighbors whether they have trouble. Shared backups go to Cobb County Water System.
- Check the cleanout for standing water.
- Have a plumber clear the line and send a camera through it.
- If the damage is near the street, ask Cobb where its responsibility ends; its published rule covers the water line only.
- Plan for a city permit. Kennesaw Building Services takes all permit applications online through iWorQ.
Signs and what they usually mean
| Sign | Probable cause |
|---|---|
| Backup returns after clearing | Belly, offset joint or broken section |
| Water stands in one spot on camera | Sag from settled soil |
| Basement drain fills first | Restriction in the main lateral |
| New wet spot after yard work | Pipe cracked by digging |
Cost factors
- Distance and depth to Cobb's sewer
- Whether the pipe can be lined or burst instead of trenched
- Paving, decks or landscaping over the route
- Interior drain pipe replaced at the same time
- Permit and inspection through Kennesaw Building Services, which enforces the 2024 International Plumbing Code with Georgia Amendments
A sag is the one problem trenchless methods can't fix, because the new pipe follows the old path. If the camera shows standing water along a stretch, expect that section to be dug and re-laid at a proper slope. The rest of the run may still be a candidate for lining or bursting, so a combined approach is sometimes the most economical. Ask the plumber to mark on a sketch which parts will be dug and which won't, so you can plan around the yard work.
