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.

Alaska has 227 active non-transient non-community water systems, 17% of the state's 1,322 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 23 Alaska systems (1.7%) list purchased groundwater as their primary source.
