Construction Technology How-to video’s for Watsan Devices Published on YouTube

Tue, 05Jan2010

An organization out of Germany called EMS has produced and posted on YouTube  a great set of educational videos surrounding the building of  of storage tanks, pumps, solar heater, wells, latrines and many other relate watsan devises.  It is apparent that it comes from their first hand experience:  “More than 10,000 wells have been drilled in South America since introduction of the EMAS concept “assistance to self-help”. EMAS stands for “Escuela Movil Aguas Y Saneamiento Basico” (Mobile school for drinkable water and sanitation) Their home site site is also in Spanish and German

The videos are designed to be understood by watching without use of audio commentary. There are bylines in Spanish and English to introduce a topic and  to indicate time lapsed but that is it.  Music is overlayed with the sounds of sawing  troweling and pumping. They are filmed  in a great style such that one quickly catches on to  concepts.  Obviously, don’t expect to master the skills presented just by watching. There is bound to be some trial and error. The following  list of videos  as of Jan 4 2009. IT looks like it will grow. The videos titled General – introducing the EMAS technologies – part 1 (view below) & part 2 is a great place to start, to see a sampling of what it is all about.

    I found your site while researching information about water wells for a friend. The videos and technology is Great! More people would benefit from these videos if they only were aware of their existance! Thank You for the work and help that you provide people that need good drinking water.
