For some instructive videos on hand drilling techniques go to www.vimeo.com and search for EMAS and water They show use of temporary casing and hand auger or sand bailer to advance the casing. There are several hours of video on various hand drilling and sell supply hand pump techniques using very limited resources. Even sessions on solar water heaters, ferrocement tanks and constructing ram pumps. https://vimeo.com/8356556, https://vimeo.com/8357733
