I am putting pool in and right next to the pool a pool house, shed. Well in order to put the shed where I want I have cut out a hill and have a retaining wall built. The problem is my septic line to my drain fields passes right thru this area and at the upper part of the hill I will only be leaving about 5 or 6 inches or dirt on top of the pipe. For the most part water is almost always flowing thru this thing but I'm going to try to insulate it as much as possible. Also the shed will be on top of most of it so I'm hoping that provides some insulation as well. I know this is kinda off topic but if anyone has any direction I would appreciate it.
