On behalf of the Pittsburgh Water and Sewer Authority, I apologize for the inconvenience caused by the mandatory flush and boil water advisory impacting approximately 7,000 homes in some central and eastern sections of the City of Pittsburgh. This is a precautionary measure caused by a very large water main break earlier today.
The decision to issue the advisory was made in consultation with our state and county regulators, and PWSA made every effort to limit the impact area using data from social media, 311, and our emergency phone line we identified those locations that had no pressure, which is a regulatory indicator of potential water quality concerns. This was a time-consuming process, but ultimately limited the overall inconvenience to our customers.
Though our regulations require the precautionary flush and boil water advisory, disinfectant levels in our system have remained stable, and we have not detected the presence of any contaminants. Regulations require multiple follow-up water quality testing before the advisory can be lifted. The earliest the test results will be available is the evening of December 19, 2017.
PWSA has contacted the impacted schools and hospitals to notify them of the advisory and provide bottled water, if necessary. There is currently a water buffalo located at Centre Avenue and S. Euclid for those without water due to the main break on Centre and S. Negley avenues. Additional water buffalo locations will be announced tomorrow morning for those in the impact area who are unable to boil water for consumption.
Again, we apologize for the inconvenience and will continue to provide you with updated information as it becomes available. Please use the searchable map to determine if your home or business is located in the impacted area.
