Wish I could dig a well but I live on a ridge and unless I hit a fountain of some sort which is very unlikely I would need to bore quite deep. I have a rainwater tank for essential water but that really doesnt last very long.
If you're a DIY type you could drill your own borehole using percussion drilling.
It's a slower process but is cheap and you can even drill through solid rock.
A borehole was hand drilled in China in 1923 to a depth of over 4000 feet (over 1200 meters) using percussion drilling so the method is very capable.
