Nearly $400 billion over two decades is needed to upgrade aging water infrastructure systems in the U.S., according to the Environmental Protection Agency. The Drinking Water Infrastructure Needs Survey and Assessment, done every four years, says many systems are 50 to 100 years old. Among the most urgent needs are the replacement or upgrade of "aging or deteriorating water lines" that would cost an estimated $247.5 billion. California, Texas and New York have the greatest need, according to the survey.
