Excavating questions, answered by experts

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.

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.

The answer may vary based on where you live. Residential sewer lines are generally buried 5 feet to 6 feet under the ground. However, it's not uncommon to see pipes buried as deep as 8 feet in colder climates in order to ensure that piping is placed below the freeze line. Digging depth could impact your sewer line replacement cost.

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

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.
