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. Schools, factories, office buildings and hospitals with their own supply are typical examples. Colorado has 183 active non-transient non-community water systems, 8.3% of the state's 2,207 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 34 Colorado systems (1.5%) list purchased groundwater as their primary source.
