How does Tortilla Flat Resort compare with other water systems in Maricopa County?

By EPA's size categories, Tortilla Flat Resort is a very small system (500 people or fewer). Maricopa County has 217 active public water systems. Its population served is well below the county average of 20,368 people per system, and accounts for less than 0.1% of the 4,419,761 people reported by systems filed under the county. Across Arizona, the 1,769 active systems average 4,369 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Tortilla Flat Resort is well below that figure.

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

Arizona has 601 active transient non-community water systems, 34% of the state's 1,769 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,612 Arizona systems (91%) list groundwater as their primary source.

Who owns and regulates Tortilla Flat Resort?

Does Tortilla Flat Resort have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in November 2025. The violations listed here began between October 2023 and November 2025. By type: 7 monitoring, 4 reporting and 1 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (11 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.
