. …………The American Society of Civil Engineers, in a report released last week, essentially described the state of American infrastructure as dreadful. More than a quarter of the nation’s bridges were rated structurally deficient or functionally obsolete. Public transportation systems and the nation’s dams and levees are generally in sorry shape, many of them more than a half-century old.

Listen to what the report had to say about the water we drink:

“America’s drinking water systems face an annual shortfall of at least $11 billion to replace aging facilities that are near the end of their useful life and to comply with existing and future federal water regulations. This does not account for growth in the demand for drinking water over the next 20 years. Leaking pipes lose an estimated seven billion gallons of clean drinking water a day.”

The society gave the nation’s infrastructure an overall grade of D and said it would require an investment of $2.2 trillion over five years to get it back into decent shape ………………..
