A leach field is an important part of a septic system. It disperses fluid from the septic system over a large area of soil adjacent to the building it services.he distribution box has another pipe that leads to the leach field. From this pipe, you will dig the trenches. Decide where to dig your trenches. You will need to dig three trenches, each about 12 inches wide and 20 feet long.
What is a Leach Field? Good question and one that is usually only asked if you have a septic problem or are installing a new septic tank system. A leach field, or septic drain field, along with the septic tank and distribution box makes up your entire sewage treatment system. When properly installed and well maintained, your leach field is âout of sight and out of mindâ as it quietly goes about its job.
