Not sure where to post this...irrigation seemed like it's somewhat close so I hope some of you can help me.
Years ago (10 - 15 yrs) I saw quite a few ads in magazines like Mother Earth News showing a water drilling device that seemed very simple...it used water to bore a well. If I remember right the ads indicated you could drill hundreds of feet deep until you found water. The device did not use a drill bit...simply hydraulic pressure/flow to create the well hole.
Does this ring a bell with anyone? I suspect it turned out to be bogus because I don't see those ads anymore...but if it's valid I'd like to investigate it more.
Any help? thank you!
