WSSC begins installing new water pipes designed to last a century

Maryland’s largest water utility says it’s among the first in the country to begin installing a new kind of water main with a protective wrap that is designed to withstand breaks for a century or more, compared with the 50 to 75 years its current pipes typically last.

The Washington Suburban Sanitary Commission said the new pipes are made of ductile iron, like many of its current mains, but have an additional zinc coating and a thick plastic “bio-wrap” that ward off corrosion.

WSSC officials say the Washington suburbs will still see hundreds of water main breaks this year, particularly when the region’s topsy-turvy winter weather taxes them. But as broken and aging mains are gradually replaced with the more corrosion-resistant pipes, utility officials say, future generations should see fewer breaks snarling their traffic, flooding their homes and cutting off their water during repairs. Their streets also will be dug up less often for pipes to be replaced.
