How does Daystar Properties compare with other water systems in Ozaukee County?

By EPA's size categories, Daystar Properties is a very small system (500 people or fewer). Ozaukee County has 249 active public water systems.

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 Daystar Properties 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.

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.
