Excavating questions, answered by experts

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

Drilled wells have a pipe sticking up that’s covered in a plastic or metal casing. On the other hand, a dug well will look like a big hole in the ground and is more similar to what you’d see in a fantasy or Western movie. If you want to be sure, contact the city for documentation on your property’s construction and excavation history. 

Yes, you can excavate in the winter, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.

Yes, chipmunk holes may have two or more entrances. Chipmunks can create an entire network of burrows. Having multiple entrances makes it easier for them when trying to escape from a predator, such as a snake, or if an entrance collapses due to flooding. Each entrance leads to the nesting chamber underground, which is where the chipmunk spends the majority of its time sleeping.
