Excavating questions, answered by experts

It takes one hour to dig a 10-foot trench by hand. Use a trenching shovel with a sharp tip and a long head. Plan for more time if your soil is heavy or rocky. Consider renting a trencher if you’re digging a long or deep trench or if you have challenging soil or terrain. 

You should dig 3 to 6 inches deep for plastic edging. Dig as wide as you need to fit your plastic edging into it—2 inches is usually sufficient.

Maintain open communication and address issues as they arise, ensuring contract terms cover potential delays.

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.

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.
