Water supply is a lifeline essential to our lives, and it is essential to ensure the sustainability of a stable supply of safe water. For this reason, early recovery from disasters is necessary, and the promotion of advance measures such as BCP (business continuity plan) is essential. In this study, we focused on the water supply in Hyogo Prefecture, particularly on water purification plants that supply safe water every day, and examined the impact and challenges of future natural disasters on water purification plants, the necessity of BCP for water supply, and the risk of damage from natural disasters based on the results of a questionnaire survey and spatial information analysis using GIS. The questionnaire survey revealed that countermeasures have not been implemented in some of these facilities. It was revealed that the main bottlenecks preventing the progress of countermeasures are a shortage of staff and securing a budget for costs. In addition, the results of spatial information analysis revealed that there are several water purification plants that are at risk of being affected by various natural disasters.
