How does Jumbo Cg compare with other water systems in Mesa County?

By EPA's size categories, Jumbo Cg is a very small system (500 people or fewer). Mesa County has 30 active public water systems. Its population served is well below the county average of 5,438 people per system, and accounts for less than 0.1% of the 163,137 people reported by systems filed under the county. Across Colorado, the 2,207 active systems average 3,400 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Jumbo Cg is about half of that figure.

Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,437 Colorado systems (65%) list groundwater as their primary source.
