Tokyo sewerage system plays a vital role in ensuring a safe and pleasant living environment and in the makeup of a healthy water circulation system. In addition to cleaning water that is dirtied by use in the daily lives and activities of Tokyo residents and returning that water to the rivers and sea, the system also speedily removes rainwater from land surface of cities.
Here, we would like to introduce the business summary of our bureau and its main policies.

We call the wastewater treatment plant "Water Reclamation Center." The name (Water Reclamation Center) not only provides an easy explanation of the role of cleaning wastewater and returning that water to the rivers and sea, but also of the new role of using the treated water for toilets in buildings and for resurrection of limpid streams.
We manage 20 water reclamation centers (13 in ward area and 7 in Tama area), with each center promoting various measures to be more friendly with the community in the region. Among these water reclamation centers, we will introduce the 7 centers that receive many foreign visitors .
