MANCHESTER Water System
Consumer Confidence Report status
MANCHESTER 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 2 items for MANCHESTER that are 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.

MANCHESTER is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, serving 104 people from groundwater.
As of August 1, 2026, its federal record holds 115 entries between 1991 and 2026, of which 2 remain open; none are health-based.
Of the 115, 110 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 synthetic organic chemicals, the Total Coliform Rules, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.

Common questions
Is MANCHESTER required to publish a Consumer Confidence Report?
- Yes. MANCHESTER 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 MANCHESTER’s next Consumer Confidence Report due?
- MANCHESTER’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does MANCHESTER have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show 2 items for MANCHESTER that are 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.
