In these pages the "do it yourself well drilling" technique is referred to as well drilling, but many call this technique "washing" or "jetting" a well. It is very similar to the rotary bit method which most real water well drillers use. Water is pumped down the center of a PVC schedule 40 pipe used as both a drill stem and a drill bit. At the bottom end of the PVC a bit is fashioned by cutting teeth into the end of the PVC. The pipe is rotated back and forth as the PVC pipe is slowly worked into the ground while the cuttings are brought to the surface by the upward flow of water in the space around the pipe. If you want to dig your own well, try this technique. Be sure and check out the section on mud pump drilling. Installing a pump is probably easier than you think. Installing a well and a pump can save a lot of money, especially if you are now paying the local utiilty for irrigation water. It is great for gardeners. Adequate irrigation will obviously increase crop output. I got a little off point, I suppose, with the sections on geothermal heat pumps and my electric bill war but Ihope you will find it interesting. The links below describe the steps in detail.
