This is basically an easier way of drilling a deep sandpoint well without killing yourself with a sledgehammer. I will be drilling my own well this summer on my hunting property.
Two questions come to mind, (a) Wonder how many gallons of water is typically used when hydro -drilling? (b) How to accomplish this if one does not already have a pressurized water source on site?
