Drinking water in Tokyo the right pipes reduce water losses by 90%

摘要

Safe, clean, palatable water costs money. Leaks incur additionalcosts as even more water must be found and treated.Dealing with leakage is a universal challenge for cities but nonehave responded more effectively than Tokyo.Starting in the 1980s the Tokyo Metropolitan GovernmentWaterworks Bureau turned to nickel-containing stainless steelpipe Type 316 (UNS S31600) for the distribution systems thattake water from the sub-mains to final destinations in homes,offices and industrial plants. It was a gradual process that took 24years to complete, but now after two decades of service it is possibleto calculate the benefits.
