Research project on safe wastewater reuse for urban poor concludes

The WHO/IDRC/FAO research project on non-treatment options for safe wastewater use in poor urban communities was concluded on 30 April 2010. The report of the final workshop in Amman, Jordan (7-10 March 2010) has now been published.

The objective of the project was to test the applicability of the third edition of the WHO Guidelines for the Safe Use of Wastewater, Excreta and Greywater in Agriculture and Aquaculture (WHO, 2006). For this purpose the following four field studies were conducted:

  • Ghana Kumasi: Evaluation of non-treatment options for maximizing public health benefits of WHO guidelines governing the use of wastewater in urban vegetable production in Ghana.
  • Ghana/Tamale: Minimizing health risks from using excreta and grey water by poor urban and peri-urban farmers in the Tamale municipality, Ghana.
  • Jordan: Safe use of greywater for agriculture in Jerash Refugee Camp: focus on technical, institutional and managerial aspects of non-treatment options.
  • Senegal: Proposition d’étude en vue de l’intégration et de l’application des normes de la réutilization des eaux usées et excréta dans l’agriculture.

The research team is now working on the final product, a Guidance Document/Manual for Sanitation Safety Plans to assist national and municipal authorities and other users of the WHO guidelines in their application.

During the 2010 Stockholm Water Week, WHO will launch the second edition of the information kit for the WHO safe use of wastewater guidelines (Sunday 5 September 17:45-18:45).

Project documents and the 2006 WHO guidelines are available on the WHO web page on Safe use of wastewater, excreta and greywater.
