Ensure availability and sustainable management of water and sanitation for all, addressing water scarcity, pollution, and inadequate sanitation facilities. Access to safe water, sanitation and hygiene is the most basic human need for health and well-being. Billions of people will lack access to these basic services in 2030 unless progress quadruples. Demand for water is rising owing to rapid population growth, urbanization and increasing water needs from agriculture, industry, and energy sectors.
