What distinguishes a Non-Transient Non-Community Water System from a Community Water System?

A Non-Transient Non-Community Water System is characterized by its service to a stable but non-residential population. Specifically, it serves at least 25 of the same people over a significant portion of the year. This contrasts with a Community Water System, which serves a permanent population that resides in a specific area year-round.

The distinction of serving the same group of people, rather than the general public or transient individuals, is crucial for understanding the types of water systems. The definition implies that while it does not provide water to a household community that remains in one place, it maintains a consistent user base, such as employees at a factory or students at a school, who are regularly present but may not call that location home.

In contrast, other options describe conditions that do not fit the definition of a Non-Transient Non-Community Water System. For instance, a system that operates during specific seasons would not provide the steady user base required for this classification, and a system that serves temporary lodging would cater to a transient population rather than maintaining a stable one.
