Restoration of Yanase River (Tokorozawa, Higashimurayama, Kiyose, Niiza and Shiki Cities, Saitama Prefecture)

Concerning Yanase River, a tributary stream of Shingashi River, running through Saitama Prefecture, the water quality was extremely deteriorated in the decade starting in 1975 because of the rapid increase of the population during the high-growth period. However, the water quality has been improved gradually as a result of the construction of a sewage system. In 2006, a river environment improvement project was started based on the “Yanase River basin water circulation master plan”. To solve water problems related to river conservation, water utilization and the water environment, river restoration activities are being conducted under cross-sectional cooperation of not only the river administrator but also the administrative agencies concerned.
