You are very resourceful! Congratulations on your new water.
Love that little path that leads to your barn, that looks gorgeous back there. It's looking so cozy and like a delightful little trek to the barn. Bet it's just beautiful in the fall too. Please post pics of your barn when you can, inside and out!
You can run the electric and phone lines in another pipe and bury it the same way. It will not need to go near as deep. Just a thought as in most areas the electic line needs to be run in a pipe anyway.
