How does Double Adobe School compare with other water systems in Cochise County?

By EPA's size categories, Double Adobe School is a very small system (500 people or fewer). Cochise County has 104 active public water systems. Its population served is well below the county average of 1,253 people per system, and accounts for less than 0.1% of the 130,277 people reported by systems filed under the county. Across Arizona, the 1,769 active systems average 4,369 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Double Adobe School 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.

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. 18 of the 104 active systems in Cochise County (17%) are also owned by a local government.
