people in the world don't have access to safe water. This is roughly one in ten of the world's population.

2.5 billion people don't have access to adequate sanitation, one in three of the world's population.

Over 500,000 children die every year from diarrhoea caused by unsafe water and poor sanitation. That's over 1,400 children a day.
