About Tokyo Waterworks Bureau


Since the waterworks in Tokyo started to supply water from the Yodobashi purification plant in 1898 as a modern waterworks, we have been implementing measures to secure water resources and improve and expand our facilities to provide a consistent, stable supply of clean water. As a result, the waterworks in Tokyo today has evolved into one of the largest facilities in the world with the highest level of technology.
