What is a transient noncommunity water system?

A transient noncommunity water system is specifically defined as a public water supply system that does not regularly serve at least 25 of the same persons for at least six months per year. This means that the users of the system are frequently changing or transient, such as those at campgrounds, parks, or schools that don’t have a consistent population that utilizes the water system year-round.

This clarity in definition is critical, as it distinguishes these systems from other public water supplies that have a more stable and continuous user base. Understanding the nature of transient noncommunity water systems is key for compliance with health regulations and management of the supply to ensure water quality standards are met for varying populations.
