Customers say: Quick response

"I wish these young men were my sons. I am proud to have had the opportunity to hire them for a somewhat complex job concerning 43 tons of soil being delivered and then correctly molded and shaped into the site that was best for my lawn. If you want to receive assurance that honesty and great American values are not dead,yet hire this company! Their price was very reasonable without the quality of their work being cheap!"

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

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.
