How does Tri-County Electric Cooperative compare with other water systems in Texas County?
By EPA's size categories, Tri-County Electric Cooperative is a very small system (500 people or fewer). Texas County has 17 active public water systems. Its population served is well below the county average of 1,102 people per system, and accounts for 0.6% of the 18,736 people reported by systems filed under the county. Across Oklahoma, the 1,254 active systems average 2,907 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Tri-County Electric Cooperative is well below that figure.
What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Oklahoma has 84 active non-transient non-community water systems, 6.7% of the state's 1,254 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 701 Oklahoma systems (56%) list groundwater as their primary source.
Who owns and regulates Tri-County Electric Cooperative?
EPA lists Tri-County Electric Cooperative as privately owned. The OK state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 5 of the 17 active systems in Texas County (29%) are also privately owned.
Does Tri-County Electric Cooperative have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in February 2026. The violations listed here began between July 2016 and February 2026. By type: 8 monitoring and reporting and 4 monitoring. The contaminant or rule involved most often is Revised Total Coliform Rule (4 of them). EPA lists 11 as resolved and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
