Sewer Excavation in Kennesaw, GA

Sewer excavation is usually discussed in terms of digging, but the decisions that matter for the decades ahead are about what goes back into the ground. When a building sewer in Kennesaw is exposed and the failed section comes out, there is a short window to choose well before everything is buried again. Sometimes the old pipe can be lined instead of replaced, which avoids most of the digging.

Choosing the pipe

Most residential sewer replacements today use plastic pipe. PVC is common, in wall thicknesses suited to buried service, and ABS turns up in some systems. Plastic is light, comes in long lengths with far fewer joints than old clay, and does not corrode the way cast iron does. Cast iron still has uses where extra strength or quiet drainage matters, though those are more often inside a building. The estimate should name the specific pipe and its wall rating rather than just saying the line will be replaced, and the pipe should be one the applicable code allows for a building sewer.

Fittings, cleanouts and the connection points

Changes in direction should use long-radius fittings that let waste and cleaning tools pass without snagging; a sharp bend buried in the yard becomes the spot where every future clog starts. A cleanout near the house, and at long runs or major turns, gives a plumber access without pulling a toilet or digging again. Where new pipe meets old pipe that is staying, a shielded coupling sized for both materials keeps the joint aligned. At the house end, the tie-in to the existing drain deserves a close look as well, since a failure there is easy to miss.

Slope belongs in the same conversation. The code sets a minimum fall that depends on pipe size, and the crew should check it with a level or laser along the whole exposed run before anything is covered, because a section laid too flat collects solids however good the pipe is.

The code behind the work in Kennesaw

Kennesaw's Building Services page lists the 2024 International Plumbing Code with Georgia amendments among the mandatory codes it shows as effective January 1, 2026. For sewer work, that is the edition that governs pipe materials, slope, fittings, cleanouts and testing. Permits for addresses inside Kennesaw come from the city's Building Services Department rather than from Cobb County, and owners who pull their own can use the department's homeowner affidavit.

What to look for before backfill

• New pipe resting on even bedding, with no rocks or gaps under it.
• A steady fall along the whole run, with no visible dips.
• Fully seated joints, and couplings with their bands tightened.
• A cleanout where you were told there would be one.
• A completed leak test and any inspection approval.

Pipe and fitting questions for Kennesaw homeowners

Is PVC strong enough under a driveway?

Properly bedded and backfilled PVC of a suitable wall thickness is widely used under driveways. Its strength in the ground comes largely from the support around it, so bedding and compaction matter as much as the pipe itself. Depth plays a part too, since shallow pipe under heavy traffic carries more load. Ask what pipe rating and bedding are planned for any section under pavement.

Why add a cleanout during a sewer replacement?

Because the next blockage, whenever it comes, is far easier to clear through a cleanout than by pulling a toilet or working down from a roof vent. A cleanout also gives a sewer camera inspection a clean entry point. With the trench already open, adding one is a small step compared with digging later just to install it.

Should the camera be run again after the repair?

It is a good idea. A short camera pass through the finished line confirms the new section sits in line with the old pipe, the couplings are smooth inside and nothing was left behind in the pipe during the work. The footage also serves as a baseline for your Kennesaw home: if a problem shows up years later, it can be compared with how the line looked when it was new.
