Trenchless International

April 2011

From the Chairman’s desk

Firstly, I want to send my condolences to members of the Japanese Society for Trenchless Technology (JSTT) and the people of Japan after the recent devastating earthquake and tsunami on 11 March 2011. On behalf of the ISTT family, I offer you our thoughts and prayers in wake of this tragedy and hope for a fast recovery.

Executive Director’s Report

Spring has arrived in many regions of the ISTT. In Washington, DC, where I live, the surest sign is the arrival of the cherry blossoms – the trees were a gift to the city from the mayor of Tokyo in 1912. This year the annual blossom festival’s theme is ‘Stand with Japan’ in the spirit of hope and rebuilding from the devastating earthquake and tsunami.
