Which of the following is an example of a Nontransient Noncommunity Water System?

A Nontransient Noncommunity Water System is defined as a water system that serves the same people over six months of the year, but those people do not reside there full-time.

Schools are an example of a Nontransient Noncommunity Water System because they typically have a stable population of students who use the facilities on a regular basis for extended periods during the day throughout the school year. Unlike transient systems, where patrons may only come for a short duration (like at camps or service stations), schools have a consistent group of users, meeting the criteria for a Nontransient system.

In contrast, travel-trailer spaces and camping grounds are characterized by a transient population that varies, making them transient systems rather than Nontransient. Similarly, service stations primarily serve customers temporarily and do not have a consistent user group, thus they do not fit the Nontransient Noncommunity classification.
