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

Groundwater means the system draws its water from wells or springs fed by underground aquifers. 5,215 Texas systems (74%) list groundwater as their primary source.

The TX state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 732 of the 1,246 active systems in Harris County (59%) are also privately owned.
