NOTICE – Seasonal Water Main Flushing – Groton Water Department
The Groton Water Department will begin the Fall flushing of the water distribution system on Tuesday, October 6th, 2026 through Thursday, October 22nd, 2026. All water main flushing occurs during the daytime hours only. We anticipate the flushing program will take approximately three weeks to complete. You will experience low water pressure and discolored water during the flushing effort, and we apologize for this inconvenience. Please be patient with us as we flush the water mains.
If you experience a prolonged period of discolored water, please run numerous cold water taps simultaneously for 5 to 10 minutes or until the water clears.
This is also a good time to thoroughly flush your hot water tank.
