The 750 - Year Replacement Schedule

From Circle of Blue blog:

"Youngstown’s population has fallen by more than 60 percent since 1960. Nearly all of the city’s 750 miles of water mains need to be replaced. In a money-saving move, the city is eliminating water and sewer service to abandoned areas and barricading roads that are empty of houses within a roughly one-square-mile zone in the city’s northeast corner. 

“It’s a mess,” Bill D’Avignon, deputy director of planning for Youngstown, Ohio, said with a hollow laugh during an interview with Circle of Blue. “It is an aging infrastructure that has not been on an adequate replacement schedule. We’re replacing about one mile per year. We’re on that 750-year replacement cycle.”"
