How does Mobile Home Properties compare with other water systems in Pima County?

By EPA's size categories, Mobile Home Properties is a very small system (500 people or fewer). Pima County has 193 active public water systems. Its population served is well below the county average of 5,896 people per system, and accounts for less than 0.1% of the 1,137,975 people reported by systems filed under the county. Across Arizona, the 1,769 active systems average 4,369 people each. Nationally, the average active community water system reports serving 6,703 people, so Mobile Home Properties is well below that figure.
