I installed a shallow well last week. Bought all the pipe parts for the well head from home depot. You pound 5’ lengths of 1 ½” schedule 40 galvanized pipe coupled together by special fittings that can can stand the stress. You put an end cap on top so as not to destroy the threads. The bottom is a 2’ section called a sand point ( it has a point on the end, holes on the side, and is shielded by screen to prevent debris from coming in) The pipe is driven in sections. Attached is a picture of Bob and his friend Sokon driving it down with a 27 lb specialty hammer called the wam bam (also from Home Depot, special order). It really helps to have a couple of beefy friends to drive the point. You test for water by dropping a string tied to a nut down the pipe. Not exactly high tech, but it doesn’t need to be. We found water 9’ below grade and drove the point down to 15’ We attached the well head to a Harbor freight 1 HP 896 Gal per minute shallow well pump ( I know , junk, but it was just suiting around the shed, and so far it works) . It’s a simple pleasure, but it was fun to see the water coming up out of the ground (the final connection was clear plastic pipe) .
