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.

System facts

System ID (PWSID): WA5312300
System type: Community Water System
Population served: 9,425
Service connections: 2,738

Water source: surface water (rivers, lakes, or reservoirs)

CHELAN WATER DEPT CITY OF is one of 112 community water systems in Washington in the 3,301 to 10,000 people size category, serving 9,425 people from surface water.

As of August 1, 2026, its federal record holds 91 entries between 1979 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
