How does Winkler School compare with other water systems in Racine County?
By EPA's size categories, Winkler School is a very small system (500 people or fewer). Racine County has 194 active public water systems. Its population served is well below the county average of 931 people per system, and accounts for less than 0.1% of the 180,595 people reported by systems filed under the county. Across Wisconsin, the 11,056 active systems average 469 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Winkler School is well below 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. Wisconsin has 891 active non-transient non-community water systems, 8.1% of the state's 11,056 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 10,978 Wisconsin systems (99%) list groundwater as their primary source.
Who owns and regulates Winkler School?
EPA lists Winkler School as owned by a local government. The WI state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 33 of the 194 active systems in Racine County (17%) are also owned by a local government.
