Tokyo Metropolitan Government has promoted measures for leakage prevention as one of our major activities. In recent years, we have been particularly targeting replacing lead pipes where leakage outbreak probability is high. In 1945, at the end of World War II, the leakage rate was about 80%. However, in 2005, the leakage rate decreased to 4.2% of the distribution water volume of 1.616 billion m3. This report describes our approach to preventing leakage.
