In a society that is experiencing a declining population, focusing on small water supply systems is important. In this article, the actual situation and the perspectives of small water supply systems managed by residents or communities were illustrated, from different points of view. In small water supply systems, priority should be assigned to securing microbial safety. Accordingly, an approach for producing safe drinking water utilizing limited data was presented. After estimating the microbial risk of the source water for a water supply facility in Kyoto City, the required level of reduction by water treatment for supplying safe water was discussed.
