As Customers Deal With Third Flush And Boil Advisory Of 2017, PWSA Head Says It’s Unacceptable

A significant water main break in Pittsburgh’s East End led the Pittsburgh Water and Sewer Authority to issue a precautionary flush and boil advisory affecting 7,000 households.
It’s the third advisory this year.
Contractors and PWSA staff have been working around the clock since Sunday morning to isolate and repair a break in a 20-inch water main on Centre Avenue near South Negley Avenue.
The vulnerabilities of that main are representative of nearly 70 percent of the water pipes in PWSA’s system, said Bob Weimar, PWSA’s interim executive director.
“And the problem is that it will break when it is exposed to a major change in temperature.” The pipes can become brittle and therefore more likely to break, he said.
In addition, Sunday’s break may have been caused by a pressure issue; a pump shut down at about the same time.
It’s unacceptable for customers to have undergone three precautionary flush and boil advisories in such a short timeframe, said Weimar.
“But we’ve taken in each case an abundance of caution to minimize the potential for any water quality problems that would affect the public,” he said.
It will take three to four days to repair the break on Centre Ave and to restore the street, said Weimar.
Water buffaloes are available to customers who are without water or unable to boil their water at: Shursave IGA Super Market at 4401 Liberty Ave, Pittsburgh, PA 15224 CVS at 4610 Centre Avenue at North Craig Street, Pittsburgh, PA 15213 Fire Station 8 at 149 North Euclid Avenue, Pittsburgh, PA 15206 PWSA will know by 5 p.m. Tuesday if the advisory can be lifted, when they receive the results of tests conducted Monday.
