PWSA continues to resolve boil water advisory

The Pittsburgh Water and Sewer Authority says no contaminants have been detected in a portion of the city’s water system, but a precautionary flush-and-boil advisory remains in effect for 100,000 customers.

The PWSA executive director Bernard Lindstrom says they are working with the Pennsylvania Department of Environmental Protection to make sure the following disinfection requirements are met:

  • Certify the Highland Park drinking water filtration plant is no longer providing inadequately treat water back into the water distribution system through an engineering analysis.
  • Conduct an analysis that water currently in the distribution system and throughout the city meets all drinking water requirements.
  • Develop and execute a plan to remove the water of concern from the system.

Lindstrom says first round tests of the water system showed that bacteria indicators are stable and chlorine is increasing.

To remove water from the system, PWSA will place flow meter on fire hydrants across the city at safe locations that won’t create public hazards when water is released.  The flow meters will provide data of how much water will be flushed out of the system and the data will be included in an analysis that will be given to the DEP.

No official time for the advisory to expire has been confirmed.

Water distribution centers have been created for customers and will remain open 24 hours until the end of the order.

The 311 Response Center and water delivery crews will start at 7:00 a.m., and remain on the same schedule until the end of the order.
