We have 5 horizontal loops running through our back yard @ approximately 6ft deep. We have a pole barn in in our back yard that we would like to trench a water line and power to, but in order to get the lines to the barn, we would have to get near the horizontal loops. Recommendation for water lines is 36-40" where we live. Is it possible to do this or can I not even get near the loops? Thanks for any help.
