Household water treatment and safe storage (HWTS) is a proven intervention to improve drinking-water quality and reduce diarrhoeal disease. Achieving meaningful health gains from HWTS requires scaling-up of the intervention to those populations most at risk. Such scaling-up depends, in large part, on national enabling environments and policies. To assess the status of national HWTS policies and regulations and progress towards the global policy targets, WHO conducted a brief survey. This report details the responses from this survey and categorizes countries into three tiers of readiness to scale-up HWTS. Based on identified challenges, greater support is needed to develop and implement national HWTS policies, encourage integration with other health interventions and diarrhoeal disease prevention efforts, and strengthen monitoring, evaluation and regulation.
