Shanghai Improves Water Quality Monitoring

Shanghai has upgraded its equipment to monitor water quality in Taihu lake, the metropolis' main tap water supply.
       
That's according to the Shanghai Daily. 
        
Last week's drinking-water crisis in Wuxi, again showed the pollution of the lake. 
       
Taihu lake sits in the heart of the Yangtze delta region and provides 70 percent of Shanghai's total tap-water supply. The remainder comes from the Yangtze River.
       
The new facility is completely automated. Whenever signals of a pollution crisis are detected, a flood gate will close the pumping of water from Taihu lake within an hour, and the city will start to shift its major water source to the Yangtze River.
