The 9th International Symposium on Water Supply Technology will be held in Yokohama City, the birthplace of the country's first modern water service, for three days from Tuesday, November 20th to Thursday November 22nd, 2012. For over 20 years since the 1st symposium in 1988, the International Symposium on Water Supply Technology has been continually held on a triennial basis as an opportunity to discuss the world's current water supply problems and most recent water supply technology trends.
Under the theme of "Resilient Water Supply System - Pursuing Safety, Sustainability and Environmental Friendliness", the 9th symposium will be held with the support of the International Water Association (IWA) along with the participation of many countries from around the world. Together with a keynote speech, special lecture, and presentations by invited speakers, reports regarding cutting-edge water supply technology such as the presentations of public reports in three technical sessions will be made. In addition, based on these sessions, the problems and direction of water supply technology in the world will be summarized by a general panel discussion. A special session based on the Great East Japan Earthquake on March 11, 2011 with the theme of "Toward Water Supply Systems Resistant to Earthquake and Tsunami" will also be held at this symposium.
Finally, an exhibition to be held simultaneously with the symposium will be an excellent opportunity for business entities and companies/organizations to show the world the advanced water supply technology of Japan and to create business networks.
We sincerely look forward to everyone's participation in the 9th International Symposium on Water Supply Technology.

Masahiro Fujiwara President, Japan Water Research Center Chairman, the 9th International Symposium on Water Supply Technology Steering Committee
