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.
And when or if you put in a new septic system, most of the time, they will abandon the old leach bed and put in a new one. Also, and it may depend on location, but our type of system now requires that you have a perimeter tile and also a bypass valve so you can change from one set of tiles to another.ot sure if this applies to your situation or not. But I had to plan an alternative site for a new drain field if I ever need one. So basically I have my drain field and then another site that I can not build on. Not a huge issue for me.
