[HCG25-P05] Understanding the natural and demographic/social conditions necessary to establish autonomous management of small water supply systems
For water supply systems serving populations exceeding 5,000, and simplified water supply systems serving populations of 101 to 5,000, small-scale water supply systems serving populations of 100 or fewer are generally maintained and managed autonomously by residents. Sustaining these operations involves multiple elements, including the "quantity and quality of water sources" and their "location," "financial aspects" such as operational costs and subsidies for installation and operation, "facility-related factors" like user numbers, scale, and changes over time, and "maintenance and management," as well as "human resources" responsible for aggregating member opinions, fundraising, external relations, and securing successors.
In a previous study (Watanabe, 2022), interviews were conducted with small-scale water supply users in northern Koshu City. It was found that in six districts/water associations, integration with public water supply systems was planned, but there was a willingness among all associations to continue using small-scale water supply even after integration, although the purposes varied among the associations. The reasons for integration were mainly concerns related to "management" and "human resources," such as ensuring water source stability and securing water supply technology. Therefore, this study aimed to further expand the region and conduct interviews focusing on these two aspects. Results were obtained from the SB district, which continues to use small-scale water supply, and the OK district, which continues to use small-scale water supply even after integration with public water supply systems. By understanding the characteristics of "management" in these two districts, the study aimed to investigate the natural and demographic/social conditions necessary to establish autonomous management of small-scale water supply systems and to consider their applicability to other cases. The detailed results of the survey will be presented on the day of the event.
