How does Rancho Del Rio compare with other water systems in Eagle County?
By EPA's size categories, Rancho Del Rio is a very small system (500 people or fewer). Eagle County has 46 active public water systems. Its population served is well below the county average of 2,242 people per system, and accounts for less than 0.1% of the 103,152 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 Rancho Del Rio 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 Rancho Del Rio?
EPA lists Rancho Del Rio 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. 28 of the 46 active systems in Eagle County (61%) are also privately owned.
Does Rancho Del Rio have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in July 2025. The violations listed here began between May 2017 and July 2025. By type: 7 monitoring and reporting, 2 monitoring, 2 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved most often is E. coli (4 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.
