Which water system caters to temporary visitors rather than a permanent community?

A Transient Non-Community System is designed specifically to serve individuals who are not permanent residents of an area, such as visitors at a campground, a gas station, or a transient lodge. This type of system provides water to people who come and go, typically for short periods of time, rather than for an established residential population.

In contrast, a Community Water System is intended for a permanent residential population, providing water continuously to established communities. A Non-Public Water System generally serves private homes or is not regulated under public water system standards, while a Public Water System encompasses both community and non-community systems, primarily focusing on systems that provide water to the public but may not be specifically for transient visitors. Therefore, the emphasis on temporary access and the lack of a long-term customer base distinguishes the Transient Non-Community System as the correct answer.
