Sewer Excavation in Dunwoody, GA

Planning a sewer dig in Dunwoody means planning for an open trench: how it is protected each night, what the inspector needs to see and how the yard is put back once the pipe is approved.

One part of sewer excavation surprises homeowners more than any other: the trench often stays open after the new pipe is in. The crew is not dawdling. In Dunwoody, as in many places, buried plumbing has to be inspected in the open trench before it is covered, and that wait shapes how the site is protected and how the days are planned.

Dunwoody's underground inspection

The city code calls for an underground plumbing inspection after the trench is dug and the pipe is laid, before any backfill goes in, and the city's permits and inspections FAQs say photos are not accepted in place of an inspection. The repair itself is covered by a trade component permit, and digging should wait until the city has issued it.

Making an open trench safe at home

An open trench is a hazard for children, pets, visitors and anyone crossing the yard after dark. Ask the crew what protection they leave at the end of each day, whether temporary fencing, plywood or steel covers over the opening, or barricades with warning tape. Keep dogs leashed or indoors, since a dog can jump in and fail to climb out, and walk children around the site so they understand it is off-limits. Point deliveries and guests to a safe path. Deep trenches with soft walls may also need bracing left in place overnight, because a wall that gives way while the site is empty can undermine a nearby walk or patio.

What happens on inspection day

By the time the inspector arrives, the pipe should be exposed along its length, the joints visible, the bedding in place and a leak test set up or completed as required. The inspector looks at the material, the fittings, the slope and the test, and either approves the work or notes corrections. Anything flagged is fixed while the trench is still open and then inspected again. A failed inspection may cost a day; a problem discovered after backfill costs a second dig.

Closing the trench properly

After approval, backfill begins. The first layer around the pipe is placed carefully so the line is not knocked out of alignment, and the rest goes in layers and is compacted as it rises. Topsoil returns on top, and the lawn is seeded or sodded according to the agreement. Plan on watering new seed or sod regularly for the first few weeks and filling any low spots that appear as the trench settles.

Before you sign

  • Ask for the footage that shows why digging is needed; a sewer camera inspection should back up the recommendation.
  • Confirm who applies for the trade component permit and who requests the inspection.
  • Agree on the site protection left in place each night.
  • Get restoration terms in writing, including seed or sod and how irrigation and edging are handled.
  • Ask whether a trenchless repair was considered and why it was ruled out.

Open trench questions in Dunwoody

Why can't the crew send photos to the inspector and fill the trench?

Because the inspector has to see the work in person. A picture can hide a joint that is not fully seated or a flat spot in the slope, and once the trench is filled, correcting either one means digging again. A short wait for the visit costs far less than reopening a finished trench, so the crew times the dig to be ready close to the inspection date.

How long might the trench sit open?

That depends on how soon an inspection can be booked once the work is ready, which varies with the city's schedule. Crews try to time the dig so the pipe is ready shortly before the expected visit, keeping the open-trench period short. Weather can stretch it, since rain delays both the work and the inspection. Ask for a realistic estimate when the job is scheduled.

Is it safe to walk near the trench?

Stay back from the edge. Trench walls, especially in clay that has dried and cracked or soil softened by rain, can break away without warning, and the lip is often weaker than it looks. Use the paths the crew sets out, keep vehicles and loaded wheelbarrows well clear, and never step down into the trench, even to look at the pipe. Ask the crew to show you the work from a safe spot instead.
