Solution for Reducing the Water and Waste Footprints of Megacities

The Challenge

The United Nations estimates that the number of megacities with a population of more than 10 million will triple from 20 in 2003 to 61 in 2015. It is estimated that more than nine tenths of urban grow ...

The United Nations estimates that the number of megacities with a population of more than 10 million will triple from 20 in 2003 to 61 in 2015. It is estimated that more than nine tenths of urban growth will occur in developing nations, with four fifths of urban growth occurring in Asia and Africa.

Policy-makers need to implement water markets and existing economic and technological solutions for water and waste problems.

Approaches for economic solutions such as lifeline pricing systems, which differentiate between low- and high-income consumers, are available in theory and also in model regions. Solutions are also available for the technical provision of water services and reuse and treatment of waste so as to reduce water and waste footprints. To capitalize on these existing solutions, policy-makers need to act and implement appropriate policies.

    Water should be charged at its actual cost, reflecting both its nature as a scarce resource and the cost for infrastructure. Avoid subsidies, which encourage overuse.
