Restoration of Fushimi and Takahashi River (Kanazawa City, Ishikawa Prefecture)

In Fushimi and Takahashi Rivers running in the southern part of Kanazawa City, a serious problem of water quality deterioration was caused by the rapid urbanization of the surrounding areas. The water quality was such that the BOD exceeded 10 mg/l but it was improved to approximately 3 mg/l by the construction of a sewage system that started in 1976.
Today, the ascent of salmon is seen and the former clear stream has been revived. The "river festival" is held by the local people and the river space has become a place for recreation and relaxation for citizens.
Fushimi and Takahashi Rivers were recognized as rivers in which the water environment was conserved and recovered by the sewage system and designated as one the "100 revived waters."
