The Implementation Strategy for Urban Healthy Water Cycle

The purpose of this study is to provide the systematic approaches for establishing a healthy water cycle (HWC). Based on the analysis of the interaction between social water cycle and natural water cycle, the connotation and functions of HWC are briefly presented. Furthermore, a set of synthetic strategies are introduced to implement the HWC, among which the reclaimed water supply system is considered as the key element to achieve sustainable water utilization and water environment recovery. The approaches feature general, systematic and feasible. The applicability of these strategies is demonstrated by implementing the HWC program in Dalian and Shenzhen.
