(Pittsburgh, PA) According to Pittsburgh Mayor Corey O’Connor’s office, ice in the Allegheny River is blocking intake to Pittsburgh Water’s treatment plant. O’Connor made this announcement this morning and stated initially that this may impact pressure and water service, especially in higher elevation neighborhoods. The blockage is also “restricting capacity and preventing normal pumping operations” in the service area of Pittsburgh Water even though service remains uninterrupted right now. Both emergency responders and Pittsburgh Water are working to clear the ice formation, eventually with the help of a barge and tugboat and levels of water in storage tanks are being monitored.
