Abstract
Wastewater reuse systems have been increasing in some urban areas in Japan recently. In this study, the present status of wastewater reuse systems was investigated with a questionnaire and a hearing survey of operators of wastewater reuse systems. Furthermore, the consciousness of users was investigated with a user questionnaire. The results obtained were summarized as follows: (1) In case of using the toilet flush water as a part of source, number of troubles on the water quality was increased compared with other sources; (2) Users of reuse water who had known that they had used it showed a better acceptance of reuse water than users who had used it but not known.
