Excavating questions, answered by experts

Trenchers can dig holes as narrow as 4 inches or as wide as 4 feet. Check the specifications of the trencher you rent or buy to determine how wide it will cut into the landscape. Better yet, let the excavation company know how wide you’d like the trench to be, and they can help you choose the right trencher for the job (or do it for you).

Depth is not a qualifying component of evacuation. Any human-made cut, cavity, or depression in the earth’s surface is considered excavation. The hole from excavation can be any size, shape, or depth. Excavation is used to create foundations, reservoirs, drainage ditches, and roads. Long, narrow excavations are called trenches and are often used for underground utilities.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

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.

The cost to drill a well varies, with a national average of around $5,500 for a 150-foot well. However, prices can fluctuate significantly based on several factors, including your location, the required well depth, geological conditions, local regulations, and the specific drilling methods used. For the most accurate cost assessment, it is best to research and get quotes from local well-drilling professionals in your area.
