This paper has collected more than one hundred papers about resilience at home and abroad, summarised and analysed themeaning and evaluation methods of resilience and then summarised the key issues. Through research on these papers, wefound that the current evaluation method for the water supply system seismic resilience is divided into two aspects: on theone hand, it’s based on the seismic performance of water supply system, where the system itself evaluates the resilienceabsorbs the earthquake resistance level. On the other hand, the assessment is based on the post-earthquake recovery abilityof the water supply system, namely the recovery time, recovery degree, recovery path and the resilience level of resourcesinput. Based on past seismic safety of the water supply system and research on post-earthquake recovery ability, themeaning of water supply system in seismic resilience should include two aspects of seismic safety and post-earthquakerecovery ability. From using the seismic safety evaluation method also and post-earthquake recovery ability in two angles,this paper gives a comprehensive multiple evaluation index framework of the evaluation model and points out that watersystem earthquake state resilience evaluative criteria and the requirements of the current seismic code should match
