How does Creston Center compare with other water systems in Flathead County?
By EPA's size categories, Creston Center is a very small system (500 people or fewer). Flathead County has 327 active public water systems. Its population served is well below the county average of 324 people per system, and accounts for less than 0.1% of the 105,781 people reported by systems filed under the county. Across Montana, the 2,378 active systems average 489 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Creston Center 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. Montana has 319 active non-transient non-community water systems, 13% of the state's 2,378 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,994 Montana systems (84%) list groundwater as their primary source.
Who owns and regulates Creston Center?
EPA lists Creston Center as under public/private ownership. The MT state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 3 of the 327 active systems in Flathead County (0.9%) are also under public/private ownership.
