Press Release
Why are hydrants running continuously around the city?
PWSA is continuously flushing hydrants throughout the distribution system upon request by the Pennsylvania Department of Environmental Protection (PADEP). Continuous flushing will help to stabilize water quality throughout the system. 
How does this stabilize water quality?
When PWSA circumvents a reservoir, like it has done with the Highland 1 and Lanpher Reservoirs, the change in flow patterns and rates can dislodge, or stir up water main deposits. These deposits are typical in a water system, but they can cause lower chlorine levels and must be monitored. Flushing water mains by exercising hydrants allow PWSA to monitor chlorine levels and removes deposits from the main.
Isn’t this a waste of water?
PWSA's goal is to provide the highest quality water possible, and we will conduct operations of this type whenever necessary to establish consistent water quality throughout our system. Many water systems, including PWSA, account for hydrant flushing as part of their water production and distribution. No customers adjacent to the running hydrants are being charged for this use of water. Continuous flushing of water mains manages water quality to ensure the public is properly served. 
How long will hydrant flushing last?
We will continue to conduct flushing until PWSA and PADEP deem it to be no longer necessary to ensure water quality.
