How does Timberline Lodge compare with other water systems in Grand County?
By EPA's size categories, Timberline Lodge is a very small system (500 people or fewer). Grand County has 77 active public water systems. Its population served is well below the county average of 728 people per system, and accounts for 0.1% of the 56,067 people reported by systems filed under the county.

Nationally, the average active non-transient non-community water system reports serving 430 people, so Timberline Lodge 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. Colorado has 183 active non-transient non-community water systems, 8.3% of the state's 2,207 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,437 Colorado systems (65%) list groundwater as their primary source.
Who owns and regulates Timberline Lodge?
EPA lists Timberline Lodge as privately owned. The CO state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 46 of the 77 active systems in Grand County (60%) are also privately owned.
