From The Economist:
Wishing well
More people are getting improved access to drinking water

From The Economist online
THE glass is more than half full: according to the World Health Organisation, some 5.9 billion people, or 87% of the world’s population, enjoyed access to drinking water from an “improved” source in 2008. In other words, those people had water piped to a dwelling, or got it from a public tap or a protected well. Back in 1990 only 77% of the world's population enjoyed such a luxury. Yet in some parts of the world, notably in Africa, great improvements in water supply are still needed. Some 884m people are still not using an improved water source, more than a third of them in sub-Saharan Africa. Eastern Asia has seen the greatest recent progress: 89% of the population in that region now have access to an improved water source, up from just 69% in 1990.
