2026 Hydrant Flushing

(Waterbury, CT) The City of Waterbury Water Department will begin its annual fire hydrant flushing program during the week of April 1, 2026. This routine maintenance program helps maintain high water quality throughout the distribution system by removing sediment from water mains, reducing mineral buildup, and inspecting fire hydrants.

Flushing activities will take place sequentially throughout the City in Zones 1 through 20 and are expected to take approximately three months to complete. Work will be conducted Monday through Friday between the hours of 8:00 a.m. and 7:00 p.m.

Residents and businesses are encouraged to review the flushing schedule to determine when their neighborhood will be affected. A map and list of streets by zone are available on the City of Waterbury website at:

During flushing operations, customers may experience temporary fluctuations in water pressure as well as brief water discoloration. This discoloration is caused by harmless sediment that may be stirred up in the water mains. While the water remains safe, residents are advised to avoid using washing machines, dishwashers, and other water-consuming appliances until flushing in their area has been completed and the water has cleared. Using these appliances during flushing may result in discolored laundry and may require additional washing.

In most cases, water clarity will return within a few minutes after flushing has concluded. If discoloration persists for longer than two hours, residents should contact the Water Department at (203) 574-8251 (press 1). Additional information is also available on the City s website at:

This annual maintenance program plays an important role in ensuring the continued quality, safety, and reliability of Waterbury s drinking water system. The City appreciates the patience and cooperation of residents and businesses while this work is underway.
