Clean drinking water is a vital part of the urban life support system and affects the lives and health of all urban residents. Therefore, the United Nations lists it as one of the important Sustainable Development Goals (SDGs). Under the disaster threats, the vulnerability of the urban drinking water system is a critical issue. If the vulnerability of an urban drinking water system can be diagnosed at the early stage, it will help the related authorities to propose improvement strategies and adjustments, thereby enhancing the city resilience. Most previous studies had discussed the vulnerability of drinking water or water resources from the national scale; however, few papers had focused on the vulnerability of urban drinking water systems. Hence, the purpose of this study was to discuss the evaluation system of urban drinking water vulnerability. The opinions of relevant experts were collected by the Delphi method, and then the important evaluation indicators were selected finally. The questionnaire of the evaluation indicators system of urban drinking water vulnerability were designed based on the systematic literature review and analysis. It was divided into four main categories, including 'water source,' 'water purification,' 'water distribution,' and 'water usage,' and it had 53 candidate indicators entirely. A total of 12 experts participated the Delphi questionnaire survey. According to the results, the categories of 'water purification' and 'water distribution' were most important, showing that the drinking water management authority's ability to handle the critical issues greatly affects the vulnerability of urban drinking water system significantly. Experts also emphasized to establish formal drinking water governance system to cope critical issues under the disaster. In addition, the indicators that selected in this study can represent the special situation of Taiwan's cities. Cities of northern Taiwan were assessed and tested by this system and the results were discussed, and it indicated that the indicators were indeed representative. This evaluation system may be used to assess the vulnerability of drinking water system in the city.
