When is POWER CITY WATER CO-OP’s next Consumer Confidence Report due?

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.

POWER CITY WATER CO-OP Water System

Consumer Confidence Report status

POWER CITY WATER CO-OP must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.

As of August 1, 2026, EPA's federal records show no open violations for POWER CITY WATER CO-OP.

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 Oregon’s official records. Always confirm current status with Oregon before making decisions based on this information.

System facts

System ID (PWSID): OR4100375
System type: Community Water System
Population served: 70
Service connections: 35
Ownership: privately owned
Water source: groundwater (wells)

POWER CITY WATER CO-OP is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 70 people from groundwater.

As of August 1, 2026, its federal record holds 80 entries between 1976 and 2025, all of which EPA lists as closed.

Of the 80, 68 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 Total Coliform Rules, volatile organic chemicals, and the Consumer Confidence Rule.
