WATERBURY, Conn. (WTIC Radio) - The City of Waterbury is letting the public know about planned repairs to a major water main that broke earlier in December.
The City of Waterbury Water Department will resume work on the Thomaston Avenue water main in the early morning hours of Monday, December 29, 2025, to complete critical repairs.
The December break on Thomaston Avenue was one of the most significant infrastructure failures the City of Waterbury has experienced in decades.
The failure of a 36-inch transmission main, following an earlier break on the same roadway, disrupted water service citywide and required an unprecedented emergency response. Crews worked over the course of nearly five days to isolate the damaged sections, construct a bypass, and restore water service safely to approximately 115,000 residents.
This phase of work will require a short, carefully controlled shutdown of the 36-inch low-pressure main so that a line stop valve can be installed. Once the valve installation is complete, the line will be immediately returned to service. Residents are not expected to experience a loss of water service during this work. The city has contingency plans in place to restore service immediately should any unforeseen issues arise.
Work is scheduled to begin at approximately 1:00 AM, a time selected due to historically low water demand. The timing of the repairs was also coordinated to minimize disruption to residents, businesses, and traffic, and to take advantage of the school winter break.
Once the water main repairs are completed, crews will begin the process of restoring the roadway, including paving the road's surface. Roadway restoration is expected to take approximately 10 additional days, weather permitting.
