Flushing will take place between the hours of 8PM-6AM.

You may experience some discoloration and/or a reduction in pressure.

The discoloration of the water will be temporary and is not harmful.

Running the cold tap for 5-10 minutes should flush out the discoloration.

The purpose of the Hydrant Flushing Program is to improve drinking water quality for residents and businesses.

Water Main Flushing

In the warmer months of the year (generally April-November), the PWSB runs the water main flushing program. The purpose of water main flushing via hydrants is to improve water quality throughout the system by removing mineral and sediment buildup from water mains. Another added benefit is the ability to verify proper operation of all hydrants in the system and evaluate the available flow to each hydrant.

In 2021 a new method of water main flushing was implemented, called unidirectional flushing (known as UDF).  With UDF, each pipeline is isolated to create flow in a single direction and quickly clean the pipe. By concentrating the flow, UDF creates higher velocities to clear the pipes and requires less water.

The unidirectional method will be the preferred option for flushing the distribution system in moving forward, as less water is utilized, and this method scours the inside pipe wall to remove “biofilm”.
