Research Center Of Ganzhou City Safe Water Supply Program

In recent years there are lots of supply accident of water because of the pollution of water . It not only brings enormous economic losses and fear, but also influences the people's life security even more. So it is the inevitable requirement for realizing sustainable and stable development of the city to settle the safe problem of the urban water supply.Recently the urban water supply in Ganzhou was threatened many times because of the water contamination accident, especially the urban water supply of the centre of the city.Based on the analysis of the present situation of the water supply system of the city centre,this text appraised the water quality and the water volume of water source Zhang Jiang and established the mathematical model of the pipe network system of the centre of the city during the accident and Obtain the safe water supply plan: In order to avoid awaits construction the chapter ofZhangjiang bridge and the pollution belt,the first water workes replace; the second water works take the water forehead to extend to the spare water source and makes groin downstream the intake of the third water workes in order to solve the water supply the problem of water volume limit. In order to reduce the energy losing along the way during the accident to insure the user's water volume and the hydraulic pressure, adding a DN800 tube from the third water works to first, adding another tube under the gold bridge, and carring on the corresponding adjustment according to the water system in the future.
