The hard facts behind the crisis.
650 million people live without safe water.
2.3 billion people don't have access to adequate sanitation, one in three of the world's population.
Over 315,000 children die every year from diarrhoeal diseases caused by unsafe water and poor sanitation. That's 900 children a day.
To end poverty, we believe everyone, everywhere must have clean water and toilets. Together we can make it happen by 2030.

Across the countries where we work, people have to walk an average of 30 minutes to collect water and return home. In some cases it can be a lot longer.
