Experience of water-supply pipeline design

Combined with actual example the problems accounting in the design of city water supply pipeline are analyzed. The performances of several common tubes and their operation situation are introduced. The different methods in foundation treatment for different geological conditions are discussed. And some concrete specification are given such as valves, expansion loop, air outlet valve, wash out valve, the type selection of abutments and so on. At last author point out that several aspects' factors should be considered and the comparison in technology and economy should be processed in pipe position's determination.
