Cobb County Water System provides sewer service in Kennesaw, and the private pipe from your house to the county system is what a plumber repairs when it cracks, sags or fills with roots. Most homes here date from the 1990s and 2000s, so laterals are generally plastic but no longer new. Call the number on this page to be connected with a local plumber in Kennesaw.
Kennesaw in brief
Kennesaw doesn't run its own water or sewer; Cobb County Water System serves the city. Housing is mostly from the 1990s and 2000s, with a median build year around 1998 and only about 11% from before 1980. PVC laterals of that age rarely corrode, but they settle, crack under driveways and lose their seal at joints, and roots from now-mature trees find those gaps. On sloped lots, gradual soil movement can also pull joints apart over time.
What to do now
- Stop using water so the backup doesn't spread.
- Keep children and pets away from any sewage and get some air moving.
- Ask nearby neighbors if they're affected. A street-wide backup belongs to Cobb County Water System's emergency line, 770-419-6201.
- If the problem is only in your home, look for the cleanout near the foundation.
- Call for a plumber and note which drain overflowed first and when.
Symptoms and what they usually mean
| What you see | Likely cause |
|---|---|
| Lowest drain backs up when other fixtures run | Blockage in the building sewer |
| Toilet bubbles while the washer drains | Partial obstruction downstream |
| Clog comes back within weeks | Roots or a low spot collecting debris |
| Damp, sunken strip in the yard | Cracked pipe or separated joint |
| Problem started after yard work | Pipe damaged by digging |
Cost factors
- Depth and length of the damaged section
- Surfaces over the pipe: lawn, a driveway, landscaping or trees
- Spot repair, lining or replacement
- Cleanout access
- Kennesaw Building Services permits, applied for online through the city's iWorQ portal; the city enforces the 2024 International Plumbing Code with Georgia amendments
Clearing the line and running a camera is the step that turns these factors into a firm quote. The footage shows where the defect is, how deep it lies and whether lining is possible, which avoids digging up more yard than necessary. Ask for a copy of the video; it's handy if the problem comes back or when you sell the house. Owners in older pockets near the historic downtown, where some homes predate 1980, should expect the camera to check for cast iron or clay as well.
