6 Does the system serve a Transient population? (A transient population is a rotating
population that is served by a water system that does not remain in the jurisdiction of
the water system for long periods of time. Examples of a transient population include,
but are not limited to, campers at a campground, users of a highway rest stop, skiers
at a ski resort, guests at a hotel, or patrons of a restaurant or a shopping center.)
