How does Spring Creek Inn compare with other water systems in Pennington County?

By EPA's size categories, Spring Creek Inn is a very small system (500 people or fewer). Pennington County has 150 active public water systems.

Across South Dakota, the 699 active systems average 1,387 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Spring Creek Inn is about half of that figure.
