What does sewer line repair involve in Kennesaw, GA?
Kennesaw homes connect to the Cobb County Water System, and the county code makes the owner responsible for the service line from the house to the county lateral. A repair means a camera run to locate the defect, then fixing or replacing that private section while the county handles its own pipe.↗

The Kennesaw story
Where Kennesaw's sewage goes
Kennesaw sits at the head of the county's northern sewer network. Cobb's Noonday Water Reclamation Facility, treating wastewater here since 1971, handles about 20 million gallons a day, and the county's Northwest plant, also in Kennesaw, adds 12 million.↗
The trunk line feeding Noonday follows its namesake creek. Noonday Creek rises near Kennesaw Mountain and runs north to Lake Allatoona, and a large sewer is buried along most of it upstream of the plant, marked by a cleared floodplain and concrete manholes.↗
None of that is your pipe. The county maintains its lateral, mains and plants. The part that backs up into your house is almost always the private service line between the foundation and the county connection.↗

Soil & terrain
Digging in Kennesaw clay
The USDA maps the middle of Kennesaw as Pacolet sandy clay loam on 6 to 10 percent slopes, severely eroded. Severely eroded means much of the original topsoil is gone, so a trench goes straight into dense red clay subsoil.↗
Clay that tight holds its shape for a clean trench but punishes poor backfill. Lines laid across a slope and backfilled in one pass can settle into bellies that hold water and solids, a pattern we look for on the camera in homes from the 1990s and 2000s.

Well drained; rated somewhat limited for septic fields because water moves slowly through it.

More about Kennesaw
How a Kennesaw repair runs
We open the cleanout, clear enough of the line to get a camera through, and record the whole run to the county connection. The locator marks each defect on the lawn with its depth, so the dig is sized to the problem rather than the whole yard.
A sag or a single cracked joint is cut out and replaced with new pipe bedded on compacted stone so it can't settle again. If the line has bellied along much of its length, we price a full replacement next to the spot repair and let you compare. Either way, a second camera pass proves the flow before we backfill.

Straight answers, with the rule or record behind them. Still unsure? Call and ask the crew that digs.
(678) 863-5620Will Cobb County repair my sewer line in Kennesaw?
Not the private part. The county code puts the service line from the house to the county lateral on the owner; the county maintains its lateral and mains.

Where does Kennesaw's wastewater get treated?
Mostly at Cobb's Noonday plant in Kennesaw, in service since 1971 at about 20 million gallons a day, with the Northwest plant also in town.

My house is only 25 years old. Why is the sewer failing?
Age isn't the only factor. On severely eroded clay slopes, poorly compacted trenches can settle into low spots that hold waste, and roots find any loose joint.

Do I have a grinder pump, and who fixes it?
If your house pumps sewage uphill to the county line, the pump is yours. Cobb's code says it won't repair or maintain those devices.

Sewage is coming out of a manhole. Is that my problem?
No, that's the county system. Call Cobb County Water System's emergency line at 770-419-6201.
Can a repair wait until I sell the house?
A known backup rarely improves, and buyers' inspectors often run a camera. Filming now tells you whether it's a spot fix or a longer replacement.
What does sewer repair cost in Kennesaw?
Published ranges run $150 to $3,800 for repairs by method and $125 to $500 for a camera inspection. A driveway poured over the line is one of the biggest local cost drivers.
