How does Tribal Administrative Building compare with other water systems in Michigan?
By EPA's size categories, Tribal Administrative Building is a very small system (500 people or fewer). 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 Tribal Administrative Building 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.
