What is a Consumer Confidence Report?

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.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Wisconsin’s official records. Always confirm current status with Wisconsin before making decisions based on this information.

System facts

System ID (PWSID): WI2680217
System type: Community Water System
Population served: 27,899
Service connections: 9,662
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

NEW BERLIN WATER UTILITY is among the 24 largest community water systems in Wisconsin, serving 27,899 people from surface water.

As of August 1, 2026, its federal record holds 78 entries between 1991 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.

Of the 78, 72 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 volatile organic chemicals, the Radionuclides and Revised Rad Rule, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
