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

Arizona has 232 active non-transient non-community water systems, 13% of the state's 1,769 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,612 Arizona systems (91%) list groundwater as their primary source.
