How does Consolidated School compare with other water systems in Rock County?
By EPA's size categories, Consolidated School is a very small system (500 people or fewer). Rock County has 156 active public water systems. Its population served is well below the county average of 952 people per system, and accounts for less than 0.1% of the 148,563 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 Consolidated 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 Consolidated School?
EPA lists Consolidated 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. 27 of the 156 active systems in Rock County (17%) are also owned by a local government.
