Hydrant Flushing

2022 Hydrant Flushing

The annual water main flushing program will begin on April 4th.  The maintenance is done in an effort to maintain good water quality, remove mineral buildup & sediment and inspect the fire hydrants.  Flushing will take place in sequence from zone 1 to zone 20 and is expected to take up to 3 months to complete.  Work is scheduled between the hours of 7:30am and 3:30pm Monday thru Friday. Please follow Mayor O'Leary's Facebook page for more timely information on weekly street flushing schedules. Special circumstances, like critical care facilities may extend flushing hours in that area. Please refer to the map and streets listed to find your zone. 

When flushing, you may experience some fluctuation in pressure because of the high velocity of water scouring the inside of the pipes and discoloration may occur from the harmless sediment that’s stirred up.

Please refrain from using the washing machine, dishwasher and other water consuming devices until the flushing is complete and the water has cleared.  This is not a health concern but more of an inconvenience. For example, laundry can become a rusty color and is in need of more cleaning with a detergent that removes the discoloration.

The water usually clears up after a few minutes but if your water continues to be discolored after an hour or more please contact the WWD at 203-574-8251 press 1 or email us at or please refer to our FAQ on discolored water.
