Millennium Development Goals Reduce by half the proportion of people without sustainable access to safe drinking water But… sobering demographics 880 million additional global population by 2015, virtually all in developing countries After 2015, all worldwide growth in population will take place in developing country cities Inadequate resources (financial or water)
The Costs of WW Treatment 73% of urban wastewater in India is untreated, requiring Rs. 2,92,500 crore (US$ 65 billion) or ten times greater than what the government proposes to invest (Infrastructure Development Finance Corp., 2003). Technology only part of the cost; land may prove to be the ultimate sticker shock
