Maintaining a small-scale water supply is one of the major issues in a declining population.
In this regard, there is a particularly large impact on drinking water supply facilities that have a service population of 100 persons or less.
In this study, model districts were selected from among small water supply nationwide, in depopulated towns and villages with populations of less than 5,000.
In addition, we also conducted management simulations over the next 60 years, for independent small-scale water systems in three neighboring regions, in which various systems such as facility integration and transported water supply, have been introduced.
Based on the results, we evaluated the superiority of future water supply systems such as facility integration, the self-sustaining distributed type, transported water supply, and the non-drinking water supply, based on the average cost burden per person per month, and discussed the optimal system to be introduced in these areas.
In addition, we considered a simple and general-purpose evaluation method that could be used to study many other future optimal systems and forms of water supply for small-scale water supplies.
We considered the form that small-scale water services should take in the future.
