Water and Sanitation

World Water Week (23-28 August 2015) brings to centre stage global issues related to water. 

Access to clean water is crucial for improving the quality of life for the world’s poorest people. Seven-fifty million people, many living in Sub-Saharan Africa, still do not have access to safe drinking water. For those who do have access, water supply is often unreliable. The inability to provide basic sanitation services has meant that one billion people still defecate in the open.

High quality evidence on water, sanitation and hygiene (WASH) programmes can provide crucial answers to what works, why and at what cost. All through World Water Week, 3ie will be highlighting the most recent evidence on WASH programmes. Watch this space.
