Press Release
June 4 - July 15, 2018

The Pittsburgh Water and Sewer Authority (PWSA) will begin inspecting and flushing fire hydrants as part of its annual distribution optimization program to ensure public safety and water quality.


Hydrant flushing is necessary to test the hydrants to ensure that adequate flow and pressure is available. Flushing also removes sediment from the distribution pipes to maintain water clarity and quality.  Running hydrants will increase water flow through the system. This increase in flow helps clear minerals and deposits from the water system.


Flushing will take place in the South Side for the month and a half (June 4 – July 15, 2018).  Boundaries will be on Carson Street, between the West End Bridge to the Birmingham Bridge, and all the streets in between.Additionally, from the Monongahela River, up to the intersection of Arlington Avenue at South 18th Street, and all streets in between.




  • Flushing will not interrupt water service; however, it is common to see a temporary reduction in water pressure while crews are working in these areas.  If customers notice low pressure after flushing is finished, they are advised to check faucets for trapped particles.
  • Water can become discolored after flushing; however, it is safe to drink. If this happens, run cold water tap for a few minutes until the water is clear. If it is not clear the first time, wait a few minutes and repeat this process.
  • Avoid washing clothes until the water clears. If laundry becomes stained, do not put it in the dryer. Rewash clothes with detergent and a rust removing agent. Rust remover can also remove stained fixtures.
  • Discoloration may linger for a few hours. Discoloration only affects the appearance of the water, but does not affect water quality. There are no health concerns associated with discolored water from hydrant flushing. 



Any customer who needs additional information should call PWSA Emergency Dispatch 24/7 at 412.255.2423
