Fire destroyed a condominium last week in the Adams Morgan section of
the city as fire fighters were unable to draw enough water from the
local hydrants to fight the blaze. The hydrants were connected to
narrow, antiquated water mains, some dating from the late 1800s.
"This incident underscores the crisis of the nation's aging
infrastructure," said Tim Burns, president of the Arlington, Virginia-
based Vinyl Institute. "It's not just a question of replacing pipe to
keep pace with growth and to avoid excess leakage; it's a question of
public safety. PVC pipe is part of the solution."
The old pipes in Adams Morgan were six inches in diameter; pipes of at
least 12 inches were needed to pump the 3,500 gallons per minute
needed to extinguish the fire. (Eventually, the firefighters unfurled
hoses 3,000 and 4,000 feet to reach mains with 20-inch pipes. No one
was seriously injured in the blaze, although property damage was
estimated in the millions.)
Al Roberson, director of security and regulatory affairs for the
American Water Works Association told the Washington Post that
efficient flow of water depended not only on size but also on the
amount of corrosion on a pipe.
Burns pointed out that, unlike other pipe materials, PVC does not
corrode or become brittle. Further, he said, "Low-maintenance PVC pipe
does not have to depend on special linings or coatings, or on a
certain level of water quality."
More and more, local governments are choosing PVC replacement pipe.
Bob Walker, executive director of Dallas-based Uni-Bell PVC Pipe
Association, said that, according to a study of buried piping
completed in 2005, "On a linear basis, PVC pipe now accounted for over
78 percent of all new drinking water pipe being installed in North
America and more than 81 percent of all new wastewater piping."
