How does Shirland School compare with other water systems in Winnebago County?
By EPA's size categories, Shirland School is a very small system (500 people or fewer). Winnebago County has 137 active public water systems. Its population served is well below the county average of 1,841 people per system, and accounts for less than 0.1% of the 252,201 people reported by systems filed under the county. Across Illinois, the 3,872 active systems average 3,204 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Shirland School 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. Schools, factories, office buildings and hospitals with their own supply are typical examples. Illinois has 396 active non-transient non-community water systems, 10% of the state's 3,872 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,808 Illinois systems (73%) list groundwater as their primary source.
Who owns and regulates Shirland School?
EPA lists Shirland School as owned by a local government. The IL state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 19 of the 137 active systems in Winnebago County (14%) are also owned by a local government.
Does Shirland School have drinking water violations?
EPA's records list 10 violations for this system; 1 is health-based, and the most recent began in October 2024. The violations listed here began between January 2008 and October 2024.

Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed.
