How does Chesterman Co compare with other water systems in Hall County?
By EPA's size categories, Chesterman Co is a very small system (500 people or fewer). Hall County has 35 active public water systems. Its population served is well below the county average of 1,755 people per system, and accounts for less than 0.1% of the 61,419 people reported by systems filed under the county.

Nationally, the average active non-transient non-community water system reports serving 430 people, so Chesterman Co 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. Nebraska has 138 active non-transient non-community water systems, 11% of the state's 1,226 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,095 Nebraska systems (89%) list groundwater as their primary source.
