The latest UN assessment is that 1.1 billion people live without access to clean drinking water and more than twice that number is denied hygienic means of sanitation. The same assessment found that while progress has been achieved in the 1990s in meeting international targets, the increase in the numbers of the absolute poor had all but wiped out the advances.

Earth Report goes to Sao Paolo, Nairobi and Manila to report on cheap community-operated schemes that offer new hope.
