Hydrant Flushing

We started the Water Improvement Project this Spring 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.

Project contractor, Hydra Tech, is scheduled to continue unidirectional flushing on Tuesday, December 10, 2019, weather permitting.  The map below indicates the area they will be working in.

Hydra Tech has made progress with exercising valves to prepare for the flushing and will continue into December, weather permitting.  The map below indicates the areas that will be focused on first.
