The Water Supply Law was amended on December 6, 2018, and in the water supply business in Japan, a contract "concession method" that transfers the operating right of public facilities to a private company for a certain period of time became possible. On the other hand, in overseas PPP-promoting countries, water services were publicized in 267 cities in 33 countries from 2000 to 2016 due to soaring water charges and uncertain management. Contracts and operations are required based on the characteristics of public services. The purpose of this study is to examine the possibility of introducing concession contracts in Japan's water supply business. We proposed a virtual management simulation model that takes risks into consideration with reference to existing water supply companies, and attempted to analyze issues in the water supply business concession.
