Three Gorges Dam
In response to the dam, many sewage pipes that once dumped sewage straight into the Yangtze River now have to be treated. Over 65 percent of this waste water is now treated before flowing into the reservoir. There are now about 50 water treatment facilities in the area. Also, solid waste is now collected in 32 landfills. They can handle 7,664.5 tons of waste every day.
