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.

Connecticut has 483 active non-transient non-community water systems, 20% of the state's 2,363 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 52 Connecticut systems (2.2%) list purchased surface water as their primary source.
