RECWET booklet
(Jul 2025 edition)

Since the establishment in 2000, we have been studying and developing cutting-edge water environment technologies using a variety of approaches based on the fusion and collaboration of basic science and practical science, with the aim of realizing a sustainable water environment.
RECWET was reorganized into three divisions in 2019 in order to strengthen and expand its research and education system through collaboration with water-related researchers in a wider range of fields, including chemistry and biotechnology and civil engineering. We have also engaged in activities such as international cooperation, human resource development, and holding international conferences, in the water field mainly in Asia.
Additionally, the "International Wastewater-based Epidemiology" Program, established in March 2024, is promoting activities aimed at social implementation of developed technologies through industry-academia collaboration.
As a research hub for water environment technology, we actively hold various symposiums and other events. More details
