WHO established the international scheme to evaluate HWTS. The Scheme aims to consistently and independently evaluate the performance of HWTS against WHO performance recommendations. The report provides the result of these assessments from a range of HWT technologies including solar, chemical, filtration and ultraviolet (UV). It highlights that of the ten HWT products evaluated, eight were found to meet WHO performance recommendations. The report also recommends specific actions at the national level needed to ensure that health gains from HWT are realized, including strengthening regulation and evaluation of HWTS.
