According to the Report, people in many parts of the world enjoy improved access to safe drinking water –86 per cent of the population in developing regions will have it by 2015. But there are still nearly one billion people without such access, and in cities the numbers are growing. Sanitation infrastructure is not keeping pace with the world’s urban population, which will almost double by 2050 to 6.3 billion people. Today, more than 80 per cent of the world’s waste water is neither collected nor treated.
