Flushing Schedule

Routine water main flushing is an important part of our ongoing efforts to maintain water quality and service in our systems. You may notice pressure fluctuations during flushing. Flushing scours the inside of the water mains and can stir up harmless sediment that can cause discolored water. This is not a health concern but we do recommend that, if possible, you avoid using the washing machine, dishwasher and other water-using devices until after flushing is completed and the water has cleared.

Discolored water can be cleared by running the cold water tap for a couple of minutes. If the water doesn’t clear after a while, or if you have specific concerns, please call Connecticut Water at 1-800-286-5700.

To find out when flushing will take place in your area, please view the Interactive Flushing Map to search for flushing dates and times or view the table below.
