Kennesaw's sewer is provided by Cobb County Water System, but the drains and building sewer serving each home are private, and that's where nearly all household clogs happen. A plumber can tell a fixture clog from a main line backup. Call the number on this page to be connected with a local plumber in Kennesaw.

Kennesaw sits beside Kennesaw Mountain along I-75 and Cobb Parkway, and its neighborhoods are mostly the planned subdivisions that filled in after 1990. The city doesn't run its own water or sewer; Cobb County Water System serves the city, and the pipes from your fixtures out to Cobb's line are yours. Housing here is mostly from the 1990s and 2000s (median year built 1998 in census survey data, with about 11% before 1980), so plastic drain pipe is the norm. Rentals and shared houses near Kennesaw State University can be hard on drains, with more grease, more wipes and more hair going down them than a single family produces.
First steps during a backup
- Stop adding water. Ask everyone to hold off on flushing, showering and laundry.
- Figure out the scope. If only one fixture is affected, the clog is local. Several at once means the main.
- Check outside. Sewage from a manhole or in the street goes to Cobb County Water System's emergency line, 770-419-6201.
- Locate the cleanout. On most Kennesaw homes it's outside near the foundation. Leave it closed if water is pushing up.
- Limit the damage. Move rugs and belongings away from low drains.
Symptoms and their usual causes
| What you notice | Usual cause |
|---|---|
| Kitchen sink backs up into the other basin | Grease and food in the kitchen drain |
| Shower drains in slow circles | Hair and soap buildup |
| Toilet backs up with normal use | Wipes, paper or an object in the toilet drain |
| Lowest fixture overflows when others run | Main line blockage |
| Recurring clog in the same spot | Roots, a sag or a buildup layer the cable left behind |
Cost factors
- How far the clog is from the access point
- Whether the cleanout is easy to reach
- Equipment used, including cable, jetter or camera
- Repair needs if the pipe is damaged
- After-hours or weekend timing
If a section of drain needs replacing, Kennesaw Building Services handles permits online and enforces the 2024 International Plumbing Code with Georgia amendments. A plain clearing doesn't involve the city at all, and most visits end once the line runs freely and the plumber has shown you what came out of it.
