In 1889, the streets of Kearney, Nebraska, were ripped open so that
workers could install sewer pipes. The railroad town boomed in the late
19th century and then quickly went bust.
Early Wednesday morning, a faulty patch failed on a water main in
suburban Washington, D.C., creating a sinkhole the size of a king bed
that closed the road above indefinitely.
Just over a week ago, heavy rains inundated the sewer system in San
Antonio, Texas. The two affected pipes spilled more than 757,000 liters
(200,000 gallons) of untreated sewage into local water bodies.
And last month, tens of thousands of gallons of raw sewage poured
from a ruptured pipe, slowing rush-hour traffic in Delray Beach,
Florida. A water department inspection later found that sewer gases had
disintegrated one-third of the 30-year-old pipe.
In ways big and small, water systems across the country are not
meeting the basic obligation to provide a reliable supply of clean
water. Pipes that deliver drinking water are rusting, clogging, and
cracking. Reservoirs are losing storage capacity. During heavy
rainstorms, sewers that combine domestic wastewater and street runoff
are pouring untreated sewage into lakes, rivers, and coastal areas.
But while the effects of America’s aging and eroding plumbing and
water supply system are readily apparent, what to do about it is not.
Like so many of the other structural challenges confronting the United
States in the early decades of the 21st century – transportation,
education, energy, health care, employment – repairing the existing
water delivery system and designing new and more efficient equipment and
practices is riven by differing views on how infrastructure investments
should be funded and which projects are priorities.
It’s not hopeless. With a sewer repair program that is more than halfway
completed and a new sewer tax that is up for renewal this month, Atlanta
is steadily making progress. Philadelphia is pursuing a 25-year program
to reduce the amount of stormwater flowing to its treatment plant by
soaking up rainfall with absorbent green roofs and more acres of green
space, by planting trees, and by restoring wetlands and riparian
habitats.
Still, other cities are inundated with old equipment and bad decisions.
The biggest municipal bankruptcy in U.S. history occurred last November
in Jefferson County, Alabama, and is tied to corruption, financial
mismanagement, and poor investments in its sewer system.
