Touchdown! Greaser!
That's what I was guessing, hence my suggestion of "going natural". I think west Texas and eastern Colorado have something in common, like not that much water.
We are in a 'water island' in west Texas, Mari. Yes most of it is semi-arid and wells to 1500' deep but we are a stone's throw from a well which, when drilled to 100', geysered!
Our water started at 40' when we drilled. There are actually hand dug wells at 12ft deep in the area although they are starting to dry up with all the fracking in our aquifer to the north.
Last year I was digging a post hole next to the rocks and at 16 inches down it started to fill with water. I thought I hit a pipe but no it was just subsurface water!
