EMAS manual well drilling is a method for drilling small-diameter tube wells by hand. This movie shows the materials needed for the EMAS technique. The main movie showing the process is available . 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 (eg ancient river beds underground). The usual diameter of the tube well is 37 mm. Movie made by Wolfgang Buchner, EMAS.

An innovative low-cost windmill for water pumping used in Nicaragua for small-scale irrigation, cattle watering and domestic use. The design is based on a Dutch model developed by CWD consultancy wind energy developing countries. The windmill drives a rope pump, similar to the hand rope pump of which 70.000 are installed in Nicaragua. Of the wind rope pump, up to now, 400 have been installed, produced by the enterprise AMEC in Managua. The technology was transferred from the Netherlands to Nicaragua through Dutch development aid, funded by the development agencies SNV and ICCO. More information: www.ropepumps.org and www.arakis.nl.
