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.
Flushing the septic tank will cause the solids to be forced into the soil absorption system and may cause irreversible damage to the leach field. Flushing water into a clogged leach field will prolong the saturation of the soils and prevent oxidation of organic material in the soil pores. 5.
