Hydrant Flushing

We started the Water Improvement Project in the spring of 2019 as an effort to clear our water mains of sediment and mineral build-up. This will not only extend the life of our water mains, but it will also improve water quality. 

This project includes Unidirectional Flushing, which involves systematically opening hydrants to “flush” mineral deposits from the pipes; and Ice Pigging, which is done by pumping an ice slurry into the main lines and forcing it along inside in order to scour the interior of the pipe and remove sediment.

We encourage you to subscribe to our website and CodeRed (our emergency notification platform). You will automatically receive updates about the project when your area is being affected.

November 21, 2020, 2:30 p.m. unidirectional flushing update: flushing has ended for the day and will continue on Monday, November 23rd at 8:00 a.m., weather permitting.

When the unidirectional flushing program was developed, the Town was divided into 12 zones to make managing the program easier. Hydra Tech completed Zone 1 on Tuesday, October 27, 2020, Zone 6 on Tuesday, October 13, 2020, and Zone 5 in March 2020. They are also scheduled to complete flushing in Zones 7 and 8, this fall.  Zones 7 and 8 require valve replacements in order for unidirectional flushing to be completed correctly. We will be scheduling these replacements over the next few weeks. Please see the map for more information about the location of the Zones.  

Due to the flushing, residents in the identified area as well as those in the vicinity of the project may experience brief periods of interrupted service, reduced pressure, or discolored water.  

If you experience discolored water once the flushing is complete, please run the cold water in downstairs bathtub until it clears. 

Hydra Tech is scheduled to work Monday through Saturday and will begin unidirectional flushing around 8:00 a.m. and end around 6:00 p.m., weather permitting.
