"Krenar and his crew did a very professional job in adding natural stone veneer to several facets of our recently repainted home; resulting in a much improved appearance. Krenar was polite and also very helpful in making suggestions on how to approach the task. He and his crew are easy to work with and highly efficient in getting the job done. I highly recommend you consider Pro House LLC for your masonry jobs. I anticipate, and look forward to, using them again in the future."

Excavating questions, answered by experts

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.

Some two-in-one tools and machines do both jobs, and those could be the right solution for smaller residential projects. However, the phrase “use the right tool for the job” definitely applies to digging. For the best results, get two separate tools for your trenching and landscape edging projects or call a pro to take care of everything for you.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

A mini excavator can dig between 5 and 11 feet deep, depending on the type and size of the mini excavator. Mini hydraulic excavators are more powerful and can reach deeper into the earth, but electric models have a more limited range. Mini excavators over two tons in size are also more powerful and able to dig as deep as 11 feet.

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.
