Cheap clean energy and better membranes would make treated water available almost anywhere, while leak control and reuse cut demand. Groundwater would be monitored and managed so that it stops falling. Universal safe water would reduce water-borne disease and free time now spent fetching water.

What it brings

  • Safe water at home for all
  • Fewer water-borne illnesses
  • Stable irrigation and food supply in dry regions
  • Less pressure on shared rivers and aquifers
