History

Zenpukuji River was designated a class A river in 1965. With urbanization, the water volume decreased dramatically, and from around 1975, there was almost no water flowing upstream. In 1989, as part of the Tokyo Metropolitan Government's Clean River Restoration Project, the highly treated sewage water that had been channeled into the Senkawa Aqueduct was diverted from the Sekimachi 1st Street intersection, where the open channel of the Senkawa Aqueduct ends, to the foot of Minoyama Bridge, where the water flows out of Zenpukuji Pond, in order to make effective use of it.
