Is WARNER required to publish a Consumer Confidence Report?

Yes. WARNER is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.

When is WARNER’s next Consumer Confidence Report due?

WARNER’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

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.

WARNER Water System

Consumer Confidence Report status

WARNER 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 1 item for WARNER that is open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.

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

System facts

System ID (PWSID): OK1020409
System type: Community Water System
Population served: 2,020
Service connections: 1,001
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

WARNER is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 2,020 people from surface water.

As of August 1, 2026, its federal record holds 51 entries between 1998 and 2025, of which 1 remains open; none are health-based.

Of the 51, 23 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, volatile organic chemicals, and the Surface Water Treatment Rules.

Common questions

Is WARNER required to publish a Consumer Confidence Report?: Yes. WARNER is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is WARNER’s next Consumer Confidence Report due?: WARNER’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does WARNER have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 1 item for WARNER that is open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.
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.
