How does Legacy Center compare with other water systems in Oakland County?

By EPA's size categories, Legacy Center is a very small system (500 people or fewer). Oakland County has 734 active public water systems. Its population served is well below the county average of 1,561 people per system, and accounts for less than 0.1% of the 1,145,905 people reported by systems filed under the county. Across Michigan, the 10,599 active systems average 847 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Legacy Center 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. Michigan has 1,402 active non-transient non-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.

Who owns and regulates Legacy Center?

EPA lists Legacy Center as privately owned. The MI state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 638 of the 734 active systems in Oakland County (87%) are also privately owned.
