PWSA Lifts Precautionary Flush and Boil Water Advisory
For Penn Avenue, between 39th and 45th streets, as well as adjacent streets
Pittsburgh, PA - Effective immediately, the precautionary flush and boil water advisory impacting residents in sections of Penn Avenue, between 39th and 45th streets, and adjacent streets has been lifted. The Pittsburgh Water and Sewer Authority (PWSA) received confirmation from two rounds of water quality testing that the water in these areas is safe to drink.
Customers in these areas are no longer required to flush or boil tap water before consumption. PWSA recommends that customers using their water for the first time in several days run their taps for at least one minute before using it for cooking or drinking. This helps remove stagnant water from plumbing and brings in fresh water from water mains.
The precautionary flush and boil water advisory was triggered after a 6-inch water main break on Penn Avenue required crews to drain a 20-inch water main. This caused low water pressure within the boundaries of the advisory on Friday, January 19th.  When there is a decrease in water pressure, it creates a risk for contaminants to enter the drinking water. This elicits the need to issue a precautionary flush and boil water advisory for the impacted area. 
When the advisory is in place PWSA must conduct two rounds of testing within a 48-hour period to confirm adequate disinfectant levels and verify that the water is safe to drink. After two consecutive rounds of testing show satisfactory results, the precautionary advisory can be lifted. We recognize the inconvenience of having to flush or boil water. However, the advisory is issued in an abundance of caution to ensure the safety of our water and customers. 
Testing has demonstrated that all drinking water requirements are being met, and there is no longer a potential risk to the drinking water supply. The advisory impacted approximately 900 households in Central and Lower Lawrenceville and Bloomfield. 
“We take the decision to issue flush and boil water advisories very seriously. Although it poses a temporary inconvenience, PWSA has a duty to prioritize the health and safety of our customers,” stated Robert Weimary, PWSA Interim Executive Director.
