There is no standard depth, but typically, septic tanks are buried between 4 inches and 4 feet underneath the earth’s surface. There are a few factors that will determine your tank’s depth, including the height of your bedrock, the distance between your home and the tank, and the depth of your main sewer line.

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.

If you’re planning to dig on your property, you’ll need to check for underground utility lines. Call the national call-before-you-dig 811 number. Once connected to an operator, you can schedule a site visit to mark underground lines. This way, you won’t accidentally dig into pipes and can cause major (read: costly) issues.

It all depends on the scope of the project. A trencher can certainly save time and energy, but you might not need to dig that deep in the first place. Aside from the depth of the trench, the quality of the soil matters. If it’s light, soft soil, you might try a shovel first. However, if the soil is rocky and hard or there are obstructions in it, like tree roots, a machine trencher might be the better option.
