RECWET booklet
(Jul 2025 edition)
Since the establishment in 2000, we have been conducting research and development of cutting-edge water environment control technologies using diverse approaches based on the integration and collaboration of basic sciences such as microbial ecology and practical studies such as water treatment engineering in order to meet the social challenges and expectations of realizing a sustainable water environment.
In 2019, the center was reorganized into three divisions. We are currently promoting research and education in collaboration with water-related researchers in a wider range of fields within the university, including Chemistry and biotechnology, Civil engineering and Material engineering. Additionally, Laboratory of International Wastewater-based Epidemiology, which was established in March 2024, is working to implement technologies developed through industry-academia collaboration in society. Furthermore, in October 2024, Shinshu University/The University of Tokyo Collaboration Branch Office was established, aiming to integrate advanced research in the water field by collaborating with Shinshu University.
Moreover, our activities in the water fields, including international cooperation, human resource development, and hosting international conferences, mainly conducted in Asia, are gaining international recognition. We will continue to promote research and education activities with the aim of becoming an international research hub for water environmental engineering.
We would appreciate your continued support for the activities of the center.
