Gu Yuliang Jin Dihui  
That water supply in Shanghai city wants to reach European standard must be on the premise of good quality and stable raw water. Development and use of great quantities of good quality Changjiang water are the best choice to change unreasonable the structure of water source and unstable water quality. Though the Chenhang Water Source supplies water with Changjiang large aquifer, the reservoir is of smaller capacity. so a series of problems have currently been emerged. Some uncertain reasons such as change of natrue and important retaining and diversion works in Changjiang River basin etc lead to the reduce of Changjiang flow into sea and salt water erosion to water intake so as to cause more unfavorable effect to Chenhang water source.
