How does Sorento compare with other water systems in Bond County?
By EPA's size categories, Sorento is a very small system (500 people or fewer). Bond County has 13 active public water systems, and Sorento is the 5th-largest of them by population served. Its population served is well below the county average of 1,368 people per system, and accounts for 2.4% of the 17,786 people reported by systems filed under the county. Across Illinois, the 3,872 active systems average 3,204 people each. Nationally, the average active community water system reports serving 6,703 people, so Sorento is well below that figure.
What does “community water system” mean?

Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 619 Illinois systems (16%) list purchased surface water as their primary source.
