Main Sewer Line Repair and Replacement in Georgia

Main sewer line repair covers the building sewer: the single pipe that carries everything from the drains in your house out to the public sewer or, on some properties, to a septic tank. When it fails, every fixture in the house is affected, which is why sewer trouble tends to show up as several problems at once rather than one slow sink. Most repairs start with a camera and end with one of three answers: clean the line, fix a section, or replace it.

Warning signs worth taking seriously

The clearest sign is a backup in the lowest drain in the house, such as a basement floor drain, a ground-floor shower or a toilet, especially when it happens as the washing machine or a tub empties elsewhere. Gurgling toilets, several drains slowing at the same time, sewage odor outdoors near the cleanout, and a soggy or sunken strip of yard over the line point the same way. A clog that returns a few weeks after being cleared usually means something in the pipe is catching waste.

What usually goes wrong underground

Roots are a frequent cause: they find their way into the joints of older clay pipe and grow into a mat that catches paper and grease. Bellies form where the soil under the pipe settles, leaving a low spot that holds water and solids. Joints separate or shift out of line, cast iron corrodes and scales from the inside, and Orangeburg, a fiber pipe used in some mid-century homes, can deform until it nearly closes. Heavy vehicles and nearby construction can crack a line as well.

Finding the fault and choosing the fix

A sewer camera inspection identifies the kind of problem and where it sits; with a locating transmitter on the camera head, its location and depth can be marked above ground. If the line is sound but coated with grease or invaded by fine roots, cleaning by hydro jetting may be enough. A single cracked or offset joint can often be fixed with a spot repair at that location. A pipe in fair shape overall but with cracks or root entry along its length may suit trenchless lining, where a resin-saturated liner is cured inside the old pipe to form a new one. Lining needs a pipe that still holds its shape, so a collapsed section or a deep belly rules it out. When the line is broken in several places or the material itself is failing, full replacement is usually the lasting fix.

When excavation is the answer

Sewer excavation means digging down to the pipe to repair or replace it. The work begins with locating the sewer and marking other buried utilities. A trench or pit is opened and shored when its depth calls for it, the damaged pipe is cut out, and the new pipe is set on proper bedding at a steady slope toward the public sewer. Building sewer work may need a permit, and some offices inspect the new pipe while the trench is still open; check with the city or county building department before digging starts. After backfill, the yard, walkway or driveway is restored to the level the estimate specifies.

What belongs in a sewer estimate

Ask for a written estimate that names the problem the camera found and its distance from the cleanout, the repair method and why it was chosen over the others, and how much pipe is being replaced and with what. It should say whether a cleanout will be added, who handles the permit if one applies, how long the drains will be out of use, and what restoration is included, from seeding bare soil to patching concrete. If lining is offered, it should state which sections are lined and which are not.

Questions about sewer line repair

Should the whole sewer line be replaced or just the damaged part?

It depends on what the camera shows along the full length. One cracked joint or a short root-damaged section in otherwise sound pipe is a good case for a spot repair. When the footage shows trouble at many joints, a failing material such as Orangeburg, or a long belly, patching one place tends to move the next failure a few feet down the line, and replacing or lining the whole run is usually the better value.

Is trenchless sewer repair always possible?

No. Every trenchless method depends on the condition of the old pipe and on getting access to it. Where the line has caved in, sagged into a deep low spot or shifted badly at a joint, that stretch is usually dug up, even when the rest can be lined. Pipe bursting, another trenchless method, needs a pit at each end and room to pull the new pipe through. A camera inspection tells you which methods fit your line before you compare prices.

Who is responsible for the part of the sewer under the street?

The property owner is usually responsible for the building sewer on the property, and the sewer provider for the public main. The section in between, under a sidewalk or street, is handled differently from one system to the next. If a camera shows the problem near the property line or beyond it, contact the sewer provider and ask where its responsibility begins.

When the drains back up

If sewage is coming up through a drain, stop running water in the house and call Alpha at (404) 409-4448. If the backup has soaked floors or walls, water damage restoration is the next step once the line is flowing again.
