Upper Lawrenceville Precautionary Flush and Boil Water Advisory Lifted
No Evidence of Contamination Found in Testing

Pittsburgh, PA - The precautionary flush and boil water advisory impacting streets in Upper Lawrenceville is no longer in effect. Two rounds of water quality testing did not show any evidence of contamination. The water in the impacted area is now safe to drink.


Customers in these areas are no longer advised to flush or boil tap water before consumption. The Pittsburgh Water and Sewer Authority (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.


PWSA experienced a break on a section of a 12" water main on McCandless Avenue at approximately 6:30 a.m. Wednesday, November 27th. This caused low or no water pressure in western portions of Upper Lawrencevile


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 and boil water. The advisory was issued in an abundance of caution to ensure the safety of our water and customers. 


Customers are encouraged to take simple precautionary steps to minimize disruptions at home by keeping several days of bottled water on hand and subscribing to our email distribution list for emergency notifications and updates. It takes less than a minute to subscribe at To receive robocalls from PWSA, customers should ensure their contact information is up to date by going to "Update Contact Info" on PWSA's homepage.
