In Poland it's quite common for people to just hand dig their wells, using concrete rings for the reinforcement of walls. It's legal up to 30 meters depth and up to 5 m^3/day water yield.
Edit: Or maybe I should say "it was" - most new wells are just a vertical steel pipe with a submerged electric pump rather than big concrete rings. These are obviously much more convenient and safer.
