Abstract—This paper figured out an action plan of China national water strategies to resolve the shortage of the available water resources in China in 2025. We divided our strategy mainly into three steps: prediction, solutions and impacts. We use the grey model GM (1, 1) to predict the water condition of China in 2025 at both a national level and a provincial level. Then, we provide two solutions in order to perfect the water condition in different areas separately. (1) Taking time value of capital into consideration, we use Dijkstra algorithm to optimize weighted topological structure of pipeline system. (2) We have established a cost model of desalination plant structure. Finally, we discuss the implications of our strategy from economic and physical aspects.
