BEIJING, March 26 (Xinhua) -- Beijing will clean all polluted rivers and ponds by the end of this year.
According to the Beijing Water Authority, there were previously about 140 polluted rivers in the city, 57 of which have been cleaned already. The rest will be cleaned by this year end.

The diversion route begins at the Danjiangkou Reservoir in central China's Hubei Province and runs across Henan and Hebei provinces before reaching Beijing and Tianjin.
Beijing has appointed more than 5,900 river chiefs, to oversee water conservation at different administrative levels.
