A draft of a 2007 combined World Bank and SEPA report stated that up to 760,000 people died prematurely each year in China because of air and water pollution. High levels of air pollution in China's cities caused to 350,000-400,000 premature deaths. Another 300,000 died because of indoor air of poor quality. There were 60,000 premature deaths each year because of water of poor quality.
In urban areas, water is tapped for domestic and industrial use from rivers, streams, lakes, ponds, wells, etc. Nearly 80% of the water supplied for domestic use passes out as wastewater. In most cases, this wastewater is let out untreated and causes large scale pollution of the surface water. A part of it percolates into the ground and contaminates the ground water. Class I cities (cities with population above one lakh) generate as much as 16,662 Mid (Million litres per day) of wastewater.
