PWSA Kicks off Annual Hydrant Inspection and Spring Cleaning Program
Pittsburgh, PA - Beginning April 15, the Pittsburgh Water and Sewer Authority (PWSA) will begin inspecting and flushing fire hydrants as part of its annual fire hydrant inspection and spring cleaning program. The program, which will be spread across PWSA’s drinking water system throughout the spring, will enhance public safety and improve drinking water quality.
Hydrant flushing is necessary to ensure adequate flow and water pressure is available for firefighting. Running hydrants will increase water flow through the system. This increase in flow helps clear minerals and deposits from the water system. Flushing also removes sediment from the distribution pipes to maintain water clarity and quality.  
Flushing will take place in the South Side for the next two weeks (April 15 – April 29, 2018).  Boundaries will be from South 18th Street to 3447 East Carson Street, and from the Monongahela River to St. Patrick Street, and all streets in between. A map of the areas impacted is available on and will be updated as the program proceeds.
If you live in an impacted area, please take note of the following:
  • 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. 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. There are no health concerns associated with discolored water from hydrant flushing.  
Customers with additional questions or concerns can call PWSA Emergency Dispatch 24/7 at 412.255.2423.
