The Water Point Data Exchange (WPDx) unlocks the potential of water point data to improve decision-making and increase rural water access. By establishing a platform for sharing water point data throughout the global water sector, WPDx adds value to the data already being collected. By bringing together diverse data sets, the water sector can establish an unprecedented understanding of water services. Sharing this data has the potential to improve water access for millions of people as a result of better information available to governments, service providers, researchers, NGOs, and others.
