Excavating questions, answered by experts

No, a ditch isn’t a trench. A ditch is an open, relatively shallow channel that’s carved out of the ground and used for drainage purposes. In contrast, a trench is a deeper excavation that’s entirely underground. Trenches have many uses, including gas lines, sewage systems, and electrical wiring. Unlike trenches, ditches don’t get filled back in with dirt after they’re dug.

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).

Preparation involves site assessment, clearing debris, grading surfaces, and compacting soil to support stable construction.

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.

As a general rule, the protected area should be about 1½ times as wide as the canopy of the tree’s leaves. This digging measurement can vary by tree species and the age of the tree. Of course, that can be a lot of fencing for larger trees, which is why our first step is about making difficult decisions on which trees to save.
