Resilience construction is an important aspect of enhancing urban disaster prevention and reduction capabilities.With the intensification of climate extremes and uncertainties,it is in-creasingly urgent to enhance the resilience of urban pipeline network systems in mega cities.This article focuses on original water channels,water supply networks,and drainage main lines,and in-troduces the main practices in resilience construction in Shanghai,including the improvement of the redundancy of raw water channels,the renovation of old water supply pipelines,the construction of situation awareness platform of water supply networks,the renovation of old drainage main lines,and the connectivity construction in the sewage area.Based on above,a general technical route for the resilience construction has been proposed,including disaster prevention,disaster response,re-silience assessment,and resilience enhancement.Finally,the prospects for future development trends are presented from three aspects,including the digital empowerment,the combination of pipeline resilience and management resilience,and the balance between resilience and efficiency.
