Launch of WHO International Scheme to Evaluate Household Water Treatment Technologies
WHO recently launched the International Scheme to Evaluate Household Water Treatment Technologies (“the Scheme”). The main objectives of the Scheme are to promote and coordinate independent and consistent testing and evaluation of HWT products based on WHO health-based performance criteria and to support governments in related technical capacity building activities.  The call for submissions for the Round I of testing has been issued and products that meet minimum criteria will be send to one of two designated testing laboratories for evaluation. For more information on the Scheme, including testing protocols and a new report on demand for testing, please visit: http://www.who.int/household_water/scheme/en/<http://www.who.int/household_water/scheme/en/
