The EMAS concept that he has developed consists of a complete set of low-cost water and sanitation technologies, such as manual well drilling, water pumps, windmills, irrigation, solar water heating, latrines, and ferrocement tanks. Movies describing all the technologies are available in this [http://vimeo.com/channels/emas EMAS Vimeo channel].
====The EMAS method====
In the course of 25 years, Wolfgang has perfected a manual drilling method which can be adapted to a range of conditions, and has trained some 400 local people in the art of well drilling. To get an impression of the drilling technique have a [http://vimeo.com/8356556 look at the movie]. The EMAS method is mainly used in Bolivia, Panama, Ecuador, Paraguay, Brazil, Peru, Honduras, Nicaragua, El Salvador, Guatemala, Eritrea and Sri Lanka.
A complete drilling rig, suitable for boreholes up to 40 metres deep, can be built in Bolivia for about $800. This includes the tower, mud pump and all essential tools to operate and maintain it. The low price means that it is very cheap for someone to start up his or her own small drilling enterprise, and this is exactly what has happened on a large scale in Bolivia, where borehole drilling services are now widely available from the local private sector.
