There is a thread about how far a leach field can be from the septic tank. This question is How close can the leach field be to a building?
I have a gently sloping area with the house at the top, and going downhill there's the wife's shed, my shop (both connected to the septic lines), then the septic tank, then the septic field. So it all works strictly by gravity. I am considering putting in a barn and the best place is just below the septic field. I've read thru the Texas requirements but can not find any mention of how close to a building a leach field can be. The barn will have to be excavated into the hill so the wall will also act as a retaining wall very much like a basement and the barn floor will probably be below the leach field lines (meaning the leach field trench was dug 3' down and the floor of the barn will probably be more like 5' down). Worse case is that I can move the leach field further downhill and have about 200' of pipe from the tank to the distribution box for the field. There are other reasons unrelated to the septic system that would make moving the field advantageous.
