"Tried two other local landscape companies and was not pleased with the quality of their work. Southampton Estate Care is a local business that has been in business for over 35 years. Ken and his team were professioal, friendly, knowledgable and VERY reliable. Will be using them from now on."

Excavating FAQs, answered by experts

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.

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.

Generally, a trenchless sewer line is worth the cost. If your old system needs replacement, trenchless sewer repair or replacement can save you thousands on excavation costs. Every homeowner’s situation is different, but this method is definitely worth it in a lot of cases.

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.

Depth is not a qualifying component of evacuation. Any human-made cut, cavity, or depression in the earth’s surface is considered excavation. The hole from excavation can be any size, shape, or depth. Excavation is used to create foundations, reservoirs, drainage ditches, and roads. Long, narrow excavations are called trenches and are often used for underground utilities.
