Excavating questions, answered by experts

The depth of a septic tank’s drain lines is between 18 and 36 inches underground. These pipes are filled with perforations and surrounded by sand, gravel, or a combination of both, as both materials help filter wastewater. While some pipes are buried closer to the surface, this can create problems unless the soil is compact and doesn’t shift much. 

In most areas, you will need a permit for excavation work, even if the project only involves grading or yard leveling. Excavation permits help protect the topography in your area and can avoid issues with poor drainage. In most cases, your excavation company will know whether or not permits are required and will even pull them and close them out for you before and after the job. You can also verify whether permits are necessary by calling your local building department and explaining the proposed project.

Preparation involves site assessment, clearing debris, grading surfaces, and compacting soil to support stable construction.

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.

Dumpsters work best on hard, study, and level surfaces made of asphalt, stone, or concrete. If the surface is uneven or too soft, the dumpster could get stuck or tip over when filled. Keep in mind that you must obtain a dumpster permit to keep it on a city street in many areas.
