Just thought I'd pass along some info for drilling your own water well. Self-help Wells is the best book I've seen for the home well driller. The book in an updated format can be seen at http://www.fao.org/docrep/X5567E/x5567e00.HTM. It can be downloaded in PDF at http://www.watersanitationhygiene.o...ATER/Hand Dug Wells/Self Help Wells (FAO).pdf. It's good information!
