Establishment of sound water environment

In the closed water areas such as the three major bays (i.e., Tokyo Bay, Ise Bay and Osaka Bay) and other designated lakes and reservoirs, water pollution by eutrophication is a serious problem. To create good water environments for life to inhabit, it is essential to try to steadily reduce non-sewer pollutant loads as well as to keep improving sewerage. Furthermore, it is necessary to promote the creation and preservation of fine waterfront spaces inside urban areas. JIWET has been carrying out joint research for the creation of a good social environment and working on the establishment of a sound water circulation system and good water environments.
