"In India and China whose urbanisation is occurring on a very large scale, we are seeing the incomes of a large number of consumers hit a "take off" level at which the consumption of many goods and services picks up speed rapidly," the report said.
McKinsey further noted that urban municipal water demand would rise by almost 80 billion cubic meters, equivalent to more than 20 times the water consumption of New York today and 40 per cent above today's urban global level."

By 2025, the annual demand for municipal water in the world's large cities is likely to increase from around 190 billion cubic meters per year today to about 270 billion cubic metres per year.
The report further noted that building or expanding the municipal water supply infrastructure will require cumulative investment of about $480 billion by 2025, including investment to increase supply and to expand the distribution and treatment of wastewater.
East and South Asia will account for more than 50 per cent of this increase in water consumption, it said.
