How does Echo Basin Ranch compare with other water systems in Montezuma County?

By EPA's size categories, Echo Basin Ranch is a very small system (500 people or fewer). Montezuma County has 17 active public water systems. Its population served is well below the county average of 1,864 people per system, and accounts for less than 0.1% of the 31,691 people reported by systems filed under the county. Across Colorado, the 2,207 active systems average 3,400 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Echo Basin Ranch is well below that figure.

What does “transient non-community water system” mean?

A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Colorado has 956 active transient non-community water systems, 43% of the state's 2,207 active systems. Groundwater under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 166 Colorado systems (7.5%) list groundwater under influence of surface water as their primary source.

Who owns and regulates Echo Basin Ranch?

EPA lists Echo Basin Ranch as privately owned. The CO state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 9 of the 17 active systems in Montezuma County (53%) are also privately owned.

Does Echo Basin Ranch have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in May 2025. The violations listed here began between August 2022 and May 2025. By type: 7 monitoring and reporting, 3 public notice, recordkeeping or other, 1 required treatment not met and 1 monitoring. The contaminant or rule involved most often is Public Notice (3 of them). EPA lists 10 as resolved and 2 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.
