PWSA Lifts Precautionary Boil Water Advisory for Mt Washington and Duquesne Heights
Advisory Remains in Place for Western Neighborhoods
Pittsburgh, PA - Pittsburgh Water and Sewer Authority (PWSA) has lifted the precautionary flush and boil water advisory impacting the Mount Washington and Duquesne Heights neighborhoods. Two rounds of bacteriological testing in these neighborhoods did not show any evidence of contamination. 
The precautionary advisory remains in place for western neighborhoods impacted when a PennDOT contractor struck PWSA's 16" water main on Shaler Street Tuesday afternoon. PWSA began collecting water samples in these neighborhoods when water was restored late yesterday afternoon. Customers in this area will be notified via robocall when the advisory is no longer in effect.
Customers using water for the first time in several days may initially notice discolored or brown water. If water is discolored, customers should run their cold water starting at the lowest fixture in the home until it runs clear. 
Water buffaloes with potable water remain at the following locations:
  • Pittsburgh Fire Bureau Station #30, 916 Steuben Street
  • Pittsburgh Fire Bureau Station #31, 3000 Chartiers Avenue
  • 1717 Hethlon Street 
  • Intersection of Springfield and Hamburg Street 
A searchable map of the impacted area still under the advisory can be found here. We recognize the inconvenience of having to flush and 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: 
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 at  
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.
