How Sewer Excavation Works
Sewer excavation is a fairly intensive process, involving heavy equipment to dig a trench that allows us to directly access the sewer line or gas line. Sewer excavation is used for sewer installation, sewer replacement, and severe sewer pipe damage that can’t be patched up with sewer relining. During sewer excavation, NJ sewer plumbing contractors will need to remove and temporarily displace relatively large amounts of dirt, sand, and gravel in order to access the part of the sewer line that we need to repair or replace.
The general process is as follows:
- NJ sewer plumbers will first measure the length that the new sewer pipe will need to be. We may be replacing the entire sewer line, or just a section of it. They’ll also take note of the soil quality around the pipe, which will affect the new sewer line installation.
- Plumbers must then perform a special set of simple calculations that help determine the right pitch for the new sewer pipes, which ensures that liquids and solids flow at the same rate. By subtracting the elevation at the start and end points of the sewer pipe, we obtain the drop per foot. To avoid sewer clogs, the ideal drop per foot is 1’4″.
- During the actual sewer excavation, a trench is dug and loose dirt is removed along the bottom if a pipe isn’t already in place. Once the line is accessible, for sewer replacement, we can replace it with all new pipes. On some properties in NJ, contractors may add sand to help prevent the underground pipes from sinking downward in loose soil.
- After new sewer pipes are laid along the bottom of the trench, the top is covered in sand, gravel, and the previously displaced soil. It may take a few months for grass and landscaping to regrow.
Sewer excavation is a slightly intrusive process for NJ homeowners, but once the process is complete, we won’t need to excavate again for years to come. Nowadays, sewer excavation is only used in certain situations, because of the recent advancements in trenchless solutions for sewer repair.
When Will We Need to Excavate?
Both homeowners and NJ sewer plumbers like to avoid sewer excavation whenever possible, in favor of alternative trenchless sewer repair solutions. However, there are still situations when trenchless sewer repair or sewer replacement methods aren’t necessarily the best choice.
We may need to opt for sewer excavation instead of trenchless sewer repairs if:
- Severe tree root infiltration. Relatively minor, nascent infiltration by tree roots can often be fixed with a combination of hydro jetting to remove the roots, and sewer relining to cover holes and cracks. However, once tree roots are in your sewer line, they can grow surprisingly fast. These thick tangles of tree roots can damage the pipe so severely that our equipment isn’t enough, and we have to access the inside of the sewer pipe directly with sewer excavation.
- Collapsed sewer pipes. There’s not much we can do for a collapsed sewer line except replace it.
