We were having sewer trouble and he stayed to see that the problem was fixed and we were no longer having problems with the sewer, even though it was after dark before he packed up his tools. We would definitely recommend Cothren Plumbing and Construction for any of your construction or plumbing needs."

Excavating questions, answered by experts

After you successfully remove your boulder, you have a few options for what to do to get rid of it. You can rent a dumpster if your yard has many boulders or if you’re planning a larger project. You can even save the boulder and reuse it elsewhere on your property to save on landscaping costs. A few ideas include using the boulder as a natural, abstract statue, breaking it into smaller pieces to line your garden bed, or offering it to a landscaping company that could reuse it for another project.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

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.

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.

Completion time ranges from days to weeks, contingent on project size, environmental conditions, and regulatory approvals.
