How does Caspian compare with other water systems in Iron County?

By EPA's size categories, Caspian is a small system (501 to 3,300 people). Iron County has 29 active public water systems, and Caspian is the 3rd-largest of them by population served. Its population served is about twice the county average of 464 people per system, and accounts for 7.4% of the 13,443 people reported by systems filed under the county. Across Michigan, the 10,599 active systems average 847 people each. Nationally, the average active community water system reports serving 6,703 people, so Caspian is well below that figure.

What does “community water system” mean?

A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Michigan has 1,332 active community water systems, 13% of the state's 10,599 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 10,214 Michigan systems (96%) list groundwater as their primary source.
