What does “non-transient non-community water system” mean?

Pennsylvania has 1,026 active non-transient non-community water systems, 14% of the state's 7,217 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 244 Pennsylvania systems (3.4%) list purchased surface water as their primary source.
