Press Release
PWSA Issues Precautionary Flush and Boil Water Advisory for Streets in Upper Lawrenceville

The Pittsburgh Water and Sewer Authority (PWSA) experienced a 12-inch water main break on McCandless Avenue, at 6:30 am, Wednesday, November 27th. This caused low and no water pressure in portions of the Upper Lawrenceville neighborhood of the City of Pittsburgh.


The main break was isolated, and crews are continuing to make repairs. When there is a water pressure loss, contaminants can enter the drinking water. In an abundance of caution, PWSA is issuing a precautionary flush and boil water advisory to a limited area, approximately 900 households, for the impacted neighborhoods highlighted in the map below. A water buffalo will be placed at McCandless Park at approximately 3:00 pm today, November 27th for those who cannot boil their water.


PWSA is conducting testing to confirm adequate disinfectant levels and verify that the water is safe to consume.


A searchable map of the impacted area is available here: PWSA Boil Water Area. Any customer who experienced no water service or low pressure in this area today is also encouraged to follow these precautionary measures until further notice. We recognize the inconvenience of having to flush or boil water. However, the advisory is issued to ensure the safety of our water and customers.



The advisory applies to water used for consumption. Customers within the impacted area should do the following before using water for drinking, making ice, washing dishes, brushing teeth, and food preparation until further notice.


For residents who do not know if their property has lead water pipes or solder, it is recommended to first flush your lines by running water from your tap for at least one minute before boiling.

  1. Boil tap water vigorously for at least one minute prior to using it for drinking or cooking (the minute starts when the water begins to bubble). This includes water used for brushing teeth, making ice, washing raw foods, preparation of drinks, and water for pets.
  2. Wait for the water to cool before using it or store it in the refrigerator in a clean container.


´╗┐Boiling kills harmful bacteria in the water that may cause illness. You should throw away ice made during the time the advisory or notice was issued, as freezing does not kill bacteria.


Flushing water brings in fresh water from the main and boiling fresh water kills any bacteria and other organisms that can enter the water. You can also use bottled water. A frequently asked questions document for boiling water can be found on the homepage.


Customers in this service area are being advised to flush their taps and then boil their fresh water to ensure that drinking water meets or exceeds all state and federal water quality requirements. The boil water advisory will remain in place until further notice. Customers with questions can go to our website homepage at or call 412.255.2423.
