Billions needed to upgrade America’s leaky water infrastructure


At first glance, the pizza-size hole that popped open when a heavy truck passed over a freshly paved District street seemed fairly minor.

Then city inspectors got on their bellies with a flashlight to peer into it. What they discovered has become far too common. A massive 19th-century brick sewer had silently eroded away, leaving a cavern beneath a street in Adams Morgan that could have swallowed most of a Metro bus.

It took three weeks and about a million dollars to repair the sewer, which was built in 1889.
