How does Ave Maria Academy compare with other water systems in Pierce County?
By EPA's size categories, Ave Maria Academy is a very small system (500 people or fewer). Pierce County has 95 active public water systems. Its population served is about 34% below the county average of 341 people per system, and accounts for 0.7% of the 32,378 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 Ave Maria Academy 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.

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.
