How does Rosewood Ranch compare with other water systems in Yavapai County?
By EPA's size categories, Rosewood Ranch is a very small system (500 people or fewer). Yavapai County has 238 active public water systems. Its population served is well below the county average of 938 people per system, and accounts for less than 0.1% of the 223,192 people reported by systems filed under the county.

Nationally, the average active non-transient non-community water system reports serving 430 people, so Rosewood Ranch 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. Arizona has 232 active non-transient non-community water systems, 13% 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 Rosewood Ranch?
EPA lists Rosewood Ranch as privately owned. The AZ state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 113 of the 238 active systems in Yavapai County (47%) are also privately owned.
