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. Indiana has 603 active non-transient non-community water systems, 15% of the state's 3,969 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 3,769 Indiana systems (95%) list groundwater as their primary source.
