WATERBURY WATER DEPARTMENT is the fifth largest community water system in Connecticut, serving 107,271 people from surface water.

As of August 1, 2026, its federal record holds 7 entries between 2006 and 2025, all of which EPA lists as closed.

Of the 7, 3 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves the Consumer Confidence Rule, the Lead and Copper Rule, and the Total Coliform Rules.

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
