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.
Water safety and quality
Water safety and quality are fundamental to human development and well-being. Providing access to safe water is one of the most effective instruments in promoting health and reducing poverty.
As the international authority on public health and water quality, WHO leads global efforts to prevent transmission of waterborne disease. This is achieved by promoting health-based regulations to governments and working with partners to promote effective risk management practices to water suppliers, communities and households.
