This is an Important Message from the Connecticut Water Company

You are receiving this notification because Connecticut Water has issued a precautionary boil water advisory for your customers in Thomaston. A water main break this morning has resulted in low, or no, water pressure. We are actively working to restore water service and ensure the quality of the water.

We encourage customers to boil their tap water as a precaution before using it for drinking, cooking, food preparation, reconstituting baby formula or using it for any purpose where it will be consumed, or customers may use bottled water for these purposes.

The water can be used without boiling for bathing, cleaning, sanitation or other purposes where the water is not consumed.  The precautionary boil advisory will remain in effect until we collect water samples and test in a state-certified laboratory to confirm that the water is free from bacteria and can be used as normal.

We expect to receive these results within 48 hours. We will notify you when the precautionary boil advisory is lifted.

We thank you for your patience and we apologize for the inconvenience.

Thank you,
Connecticut Water
