Water, sanitation and hygiene (WASH) are essential for both human survival and sustainable development. How can we ensure that everyone has access to these basic necessities? There are seven billion people in the world today. Despite huge progress in extending access to water and sanitation over the last four decades, 2.4 billion still lack access to decent toilets, and 663 million people rely on unsafe drinking water sources. The international community, in Sustainable Development Goal (SDG) 6, set out a clear ambition to ensure the availability and sustainable management of water and sanitation for everyone by 2030. We know how much it takes to do it: about three times more than current investment. And we also know about the costs of failure.
