The seismic performance evaluation of water supply systems is generally conducted in two stages: a preliminary and a detailed evaluation process. In the case of water pipelines, the priority pipes are selected through preliminary evaluation for a detailed evaluation. However, as the preliminary seismic performance evaluation method for existing water pipes solely focuses on their installation year and structural evaluation, it does not reflect the hydraulic characteristics of the water supply, which is the main purpose of water pipes. Therefore, this study proposed an evaluation method for the existing preliminary evaluation judgment index, by considering the calculation method for the probability of spatial failure, as well as the index obtained through hydraulic analysis results. The proposed methodology was applied to a domestic regional water supply system to be verified, and the results were analyzed. The proposed method is expected to serve as a result of basic research to enhance the seismic performance evaluation method in the future.
