"Here", those of us still on private wells use 1 1/4" galv pipe, basically you start off with a augered or post hole digger hole to start the point and pipe, the pipe is joined with drive couplings, if doing by hand, a fence post pounder can work, you drive the pipe down till you need to add pipe, put another drive coupler and screw on your pipe and continue pounding, repeat as necessary. A more elegant solution for the driver is an A frame with a pully on top, the pounder is attached to rope and run through the pully and now you pull and release the rope for the up and down pounder. a pounder with a 1" pipe extension UNDER the pounder lets you pound deeper before you add pipe plus the extension rides inside the well pipe to keep everything straight and together. while pounding you generally "tighten" the pipe into the coupler with a pipe wrench to keep the pipe from loosening in the coupler, everything needs to stay tight, no air leaks allowed.

Once you get to depth, hook up your hand pump to clear the well pipe of sand and dirt., plumb the well to the pump,(shallow well jet pump) don't forget the check valve, and plumb to your pressure tank if using one and plumb to your supply lines..

We have mostly sand and gravel below the top soil and loam , so the well drives pretty easy...most of the time.

If you have water already, you can jet the pipe down , just like jetting a piling for a dock.
