Excavating questions, answered by experts

It is a common belief that excavation is easier or less costly when done in the summer or when the ground is not frozen. Seasons have little effect on when excavation can occur; however, inclement weather can prolong the duration of the job and potentially increase costs. For this reason, those in rainy climates may opt for seasons with milder weather.

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

Excavations take a few days or up to a few weeks. The time it takes to excavate an area depends on the size of the area, the type of soil, the type of excavator, and even the time of year, since winter can make digging up the ground more difficult.

Tree experts don’t advise against digging through tree roots, but instead encourage caution and consultation with a local arborist to make sure you don’t damage the tree’s structure or interrupt its water or nutrient intake. An arborist can recommend specific practices when digging and help prune the roots or dig a trench for utilities with a tool that can remove soil without touching the tree’s roots.

Trenching is a specific kind of digging. Trenching means digging a depression in the earth that’s deeper than it is wide, often with heavy machinery. Digging refers to any kind of removal of earth in order to create a human-made depression, hole, or cut in the earth’s surface. You can dig with big tools or even with just a hand shovel.
