Excavating questions, answered by experts

The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.

The easier way to find buried sprinkler lines is to use the plan from the professionals who installed the system. If you don’t have professional plans, listen for running water on your lawn when you turn on the system. You may also spot wet areas, giving you an idea of where the heads are. Once you find the sprinkler heads, you’ll likely be able to connect the dots between them, revealing the system below.

There are several different factors that influence how long it takes to excavate. For a foundation, it could take anywhere from three days to three weeks. It can take even longer if you face weather-related delays or an inaccessible site that’s riddled with boulders and rough terrain. It may also take longer if you have clay soil, which is more difficult to dig.

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.

Water lines are buried at various depths, depending on the type of line. For example, most sprinkler lines are buried between four and 12 inches underground. On the other hand, water mains usually sit between one and 3 feet below ground. However, they can go even deeper in cold climates to prevent freezing.
