Water supply for detached garage

[structures282]

My house has a 20 X 20 detached garage. Although there is no utilities to the garage. I'm confident I can get the electrical run without problems. Additionally though I would like to go a step further and run a water line in the same trench as the electrical line. See attached pic I would like to take something like a 24" masonry bit and drill at an angle through the slab in the wall where the kitchen sink supply lines run. I'd like to get some advice from you guys on what approach you would take? I'm in Oklahoma on a slab foundation with like an 18" frost line.

I would recommend checking with your local zoning office. you can ask a few general questions and find out what is legal. I think it might be a little iffy to run the electrical and water in the same trench. remember how well electricity and water mix together. If they do allow it, I can guarantee that there is some minimum of separation--probably vertically and horizontally.

I believe you will need two trenches a foot or more apart. I had to put in three trenches, one for water one for electric and one for gas. The water and electric made some sense to me, but what are the chances of gas and water contaminating each other?

A future digger could cut a water line and electric cable, electrically charge the ground water and anyone in the resulting mud hole could "get it", assuming the breakers were faulty up the line. Not likely, but could happen. Gas and electic, same example could cause a gas fueled fire, but water and gas????
