Sewer Line Replacement in Marietta, GA

When a sewer line is failing along its length, patching it again and again stops making sense. Here's how a full open-trench replacement works and when it's the right call.

What This Covers

What Sewer Line Replacement Means

Sewer line replacement means installing a new sewer lateral from the house to the point where it connects to the public sewer, rather than fixing one failed spot. In a traditional (open-trench) replacement, the old line's path is excavated, the old pipe is removed, and new pipe is laid in a prepared trench at a continuous downhill slope, then connected at both ends, tested, inspected, and backfilled.

Replacement makes sense when the line has failed in more than one place, when the pipe material or condition is poor throughout, or when it keeps backing up after repairs and cleanings. It also tends to come up when a line has collapsed or when an assessment shows the pipe has sagged or shifted along much of its length.

If only a single spot has failed, a sewer line repair may be enough. If you'd rather avoid a long open trench, ask whether your property is a candidate for trenchless sewer line replacement. Our guide to repair vs. replacement compares the two decisions in detail.

  • Replacement Assessment

    The scope comes from what's found on-site: the line's path, depth, and condition. A camera inspection may be recommended when needed.

  • Open-Trench Installation

    The full path of the old line is excavated so the new pipe can be set on a prepared bed and sloped correctly along its entire length.

  • Correcting Sags & Low Spots

    Because the entire run is open, the installer can see the whole line and set the slope correctly along the full length of the new pipe.

  • Connections & Cleanouts

    The new line is tied in at the house and at the sewer connection. A properly placed cleanout gives future access for inspection and maintenance.

  • Testing, Permit & Inspection

    The work is permitted, and the open trench stays accessible until the required inspection is complete and the pipe has been tested.

  • Backfill & Restoration

    The trench is backfilled in controlled layers and the surface is restored. What restoration includes is agreed up front for the property.

What Affects a Sewer Replacement Project

Replacement cost and timing vary too much from one property to the next to generalize. These are the factors that drive them.

In the Marietta area, red clay, tree roots, and tight spacing between the house, driveway, and neighboring utilities are common site factors. Each is evaluated on the property rather than assumed.

Frequently Asked Questions

Sewer Line Replacement FAQ

Common questions about replacing a sewer line in Marietta.

When should a sewer line be replaced instead of repaired?

Replacement is usually the better choice when the line has failed in multiple places, the pipe is in poor condition along most of its length, a section has collapsed, or backups keep returning after repairs. A single isolated failure on an otherwise sound line is more often a repair candidate.

What does a sewer line replacement include?

Locating utilities, permitting, excavating the line's path, removing the old pipe, installing the new pipe at a continuous slope, connecting it at the house and the sewer, testing, inspection, backfill, and surface restoration. The exact scope for your property is confirmed in an assessment.

Will my yard be dug up?

In an open-trench replacement, yes: the path of the line is excavated. If minimizing disturbance matters, ask whether your property qualifies for trenchless sewer line replacement, which limits digging to access pits.

What will the new sewer pipe be made of?

Modern installations commonly use plastic pipe such as PVC, but the material and specification are confirmed for your job and must meet local plumbing code.

Does replacement need a permit in Marietta?

Yes, for work in the City of Marietta. The City requires a plumbing permit for work on a plumbing system, and the license holder performing the work applies for it. Properties in unincorporated Cobb County follow a separate process, so confirm which applies to your address.

Why not just keep repairing it?

Repeated repairs on a line in poor condition can cost more over time than addressing the line as a whole, and each new break risks a new backup. See repair vs. replacement for how to weigh it.
