The water supply system plays an indispensable role as one of the most important urban facilities used for our daily lives and urban activities.
A little more than 100 years have passed since modernization began with the Tokyo Bureau of Waterworks starting to supply water in 1898 from the Yodobashi Purification Plant. Since that time, we have been securing water resources and improving waterworks facilities to provide a constant and stable supply of clean water. As a result, waterworks in Tokyo have grown to be one of the largest and best waterworks in the world.
In recent years, however, customer requests for waterworks have changed. They are interested not only in quantity but also in being provided high quality tap water, having protective seismic resistance measures, and knowing that the environment will receive consideration.
Therefore, we have made a three-year management plan, to be implemented from FY 2004 to FY 2006, called the"Tokyo Waterworks Management Plan 2004". This plan aims at achieving high quality services suitable for metropolitan Tokyo.
Already, our industrial waterworks has been successful in preventing land subsidence. However, it is facing financial difficulties due to decreased demand. We are endeavoring to manage it more efficiently.
This page is prepared to enlighten readers on Tokyo Waterworks history, the outlines of projects, current problems and how Tokyo Waterworks should be in the future. We hope this page will help you in understanding the many activities and responsibilities of the Tokyo Waterworks.
