A driven well is the common water supply in the Wabash River bottoms where there is gravel underneath. Drive a point 25 ft in the ground and you can't pump it dry! Here is a UMN Extension bulletin on doing it. See: http://www.extension.umn.edu/distribution/naturalresources/DD0951.h...

I found another article by the same author on a Northern Illinois University page that give some more information See http://www.engl.niu.edu/wac/wellpoin.html

I also found this article in  google search: http://www.fdungan.com/well.htm

Just remember, it's even less fun than driving steel fence posts.

Brady Products has an interesting method of installing a point by using water instead of the old fashioned driving method. Download a pdf file at http://bradyproducts.com/documents/wellinstallation.pdf Quoting it:

1 ¼” WELL POINT
INSTALLATION INSTRUCTIONS
This brochure is designed to provide step-by-step instructional assistance to the individual who wishes to install a shallow water well system for residential sprinkler or irrigation. The procedure explained herein consist primarily of “washing” a smooth PVC casing into the water bearing sand layer, facilitating the insertion of a well point, through which water can be drawn from this layer. This procedure eliminates the need for professional well drilling equipment.
Note: This installation is for shallow water only and not recommended for systems intended for human consumption.

It is a fascinating concept for anyone who has ever used a pipe driver. Plus it uses PVC instead of steel, so it won't rust.
