"Replaced leech field- he did an excellent job removing my old leech field and replacing it with a better system. From the time I entered the job in homeadvisor (approx 8am) I was called back before noon. We scheduled a site review later that day. From the time I selected Roadway, there was constant progress. Even when the permits were in progress, they were in constant contact to let me know what was going on. When the permits were in order, they worked nonstop until the job was done. Their work was excellent, prompt and neat. Highly recommend."

Excavating questions, answered by experts

A trench that is less than 5 feet deep often doesn't require a protective system. Most residential trenches will not go this deep (the typical residential drainage trench is just 18 inches deep). In the event that an excavator needs to dig more than 5 feet beneath the surface, a protective system is required unless the excavation is in entirely stable rock.

There is no standard depth, but typically, septic tanks are buried between 4 inches and 4 feet underneath the earth’s surface. There are a few factors that will determine your tank’s depth, including the height of your bedrock, the distance between your home and the tank, and the depth of your main sewer line.

Trenches are typically 12 inches to 24 inches deep and 8 inches wide. However, your city or county may have specific ordinances that clarify the dimensions needed for the project. For instance, a water pipe may need to be 24 inches deep, but a drainage pipe may need to be 36 inches deep.

To drill a shallow well, you may be able to use a drive well point. This is a tapered point that is driven into the ground. A drill bit at the end of PVC pipe may be another option to consider. A lot of the cost depends on what tools are available near you.

The digging depth will depend on the size of the trencher you use. Even smaller units can dig up to 4 feet deep, which is plenty for a DIY job. However, much larger trenchers can reach a depth of 18 feet and are better used by a team of pro contractors, not a single DIYer. As with all home improvement projects, use the right tool for the job and proceed with caution.
