Across Nevada, the 643 active systems average 5,508 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Certain Teed Gypsum is well below that figure.
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. Nevada has 161 active non-transient non-community water systems, 25% of the state's 643 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 557 Nevada systems (87%) list groundwater as their primary source.
