In 2013, America received a “D” in the drinking-water category of the American Society for Civil Engineers’ Report Card for America’s Infrastructure. The report found that most of the nation’s drinking-water infrastructure is “nearing the end of its useful life.” Replacing the nation’s pipes would cost more than $1 trillion. The country’s wastewater infrastructure also got a “D” grade.
