Urine diversion toilet components – A Technology Review

This was first noted/posted  by SuSanA( EN FR ES ) and worthy of    “post duplicating”

GTZ Has published a set of technology reviews the last Quarter of 2009 dealing with “some
technologies commonly used as toilets or as treatment systems in ecosan systems.”

GTZ (Deutsche Gesellschaft für Technische Zusammenarbeit translated- German Agency for Technical Cooperation) is federally owned and “…supports the German Government in achieving its development-policy objectives.” according to its about us web page Thier focus is sustainable development.  Their is site is available in English and Deutsche de

The following comes  from  http://www.gtz.de/en/themen/umwelt-infrastruktur/wasser/9397.htm and the actual documents.

NOTES:

They, GTZ,  suggests the site  http://www.susana.org/lang-en/working-groups for in depth information.  SuSanA (Sustainable Sanitation Alliance) has formed working groups for a range topics centered on sanitation. Their admirable and hopefully achievable goal is to “…provide deliverables  that underline the problems and opportunities …” for these topics.  The working groups break  out as follows:

• • Working group 1 – capacity development
  • Working group 2 – costs and economics
  • Working group 3 – renewable energies, climate change and groundwater protection
  • Working group 4 – sanitation systems, technology options, hygiene and health
  • Working group 5 – food security and productive sanitation systems
  • Working group 6 – sustainable sanitation for cities and planning
  • Working group 7 – community, rural and school sanitation
  • Working group 8 – sustainable sanitation in emergency and reconstruction situations
  • Working group 9 – sanitation as a business
  • Working group 10 – public awareness and sanitation marketing
  • Working group 11 – operation and maintenance of sustainable sanitation
  • Working group 12 – gender aspects of sustainable sanitation
