Water Sanitation and Health
Our vision and mission are the attainment by all peoples of the lowest possible burden of water and sanitation-related disease through primary prevention.
Drinking-water quality guidelines
WHO produces international norms on water quality and human health in the form of guidelines that are used as the basis for regulation and standard setting world-wide.
The Guidelines for drinking-water quality (GDWQ) promote the protection of public health by advocating for the development of locally relevant standards and regulations (health based targets), adoption of preventive risk management approaches covering catchment to consumer (Water Safety Plans) and independent surveillance to ensure that Water Safety Plans are being implemented and effective and that national standards are being met.
