How does Yuma Desalting Project compare with other water systems in Yuma County?
By EPA's size categories, Yuma Desalting Project is a very small system (500 people or fewer). Yuma County has 50 active public water systems. Its population served is well below the county average of 4,392 people per system, and accounts for less than 0.1% of the 219,583 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 Yuma Desalting Project is about half of 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.

Arizona has 232 active non-transient non-community water systems, 13% of the state's 1,769 active systems. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 61 Arizona systems (3.4%) list surface water as their primary source.
