Based on cascading failure, the model of EPANET is used to analyze the system reliability of water supply network and node impact evaluation and pipeline evaluation. Then three conclusions are obtained by calculation. The first conclusion is the hydraulic reliability of the water supply pipe network is related to the node and the pipe section. And the results of the analysis can correspond to the consequences of pipeline failure which can be used as a basis for evaluating pipeline. The second conclusion is the node can be divided into the failure node and the influence node based on node impact evaluation of the water supply network. And the failure node can be set to monitor the water supply system focus because of the sensitivity of these two types of nodes to cascading failure. The third conclusion is the pipeline evaluation is a comprehensive evaluation of pipeline operation and node influence, and pipeline can be divided into key sections, the main pipe, the general pipe, and the key pipe and the main pipe are the greatest threats to the hydraulic reliability of the water supply pipe network, so they should be considered as the key part of system optimization and system monitoring.
