MANCHESTER WATER DEPARTMENT is among the 13 largest community water systems in Connecticut, serving 51,198 people from surface water.

As of August 1, 2026, its federal record holds 6 entries between 1980 and 2024, all of which EPA lists as closed.

Of the 6, 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, the Consumer Confidence Rule, and inorganic chemicals.

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.
