* EMAS has produced a set of DVDs which cover, among others EMAS drilling and other low cost water supply techniques. [http://emas.blip.tv The movies are available here]. Contact Wolfgang Buchner on [email protected] if you would like to order a copy of the movies on DVD.
EMAS manual well drilling is a method for drilling small-diameter tube wells by hand. The drilling method is a hybrid between washboring, percussion and rotary drilling. It permits to drill through all kinds of loose soils, as well as consolidated materials and light rock. It will not, however, penetrate hard original rock or boulders (e.g. ancient river beds underground). The usual diameter of the tube well is 37 mm. Movies made by Wolfgang Buchner.
