What defines a Non-Community Water System?

A Non-Community Water System is specifically defined by its service characteristics, primarily concerning the number of service connections and the duration of service to non-residents. The correct definition indicates that it is a system that has 15 or more service connections and serves 25 or more non-residents for 60 or more days. This distinction is crucial as it differentiates non-community systems from other types of water systems, such as community systems that serve year-round residents.

The rationale behind this definition lies in the types of facilities that typically utilize non-community water systems, such as schools, campgrounds, and certain businesses, where transient populations need access to safe drinking water. Identifying the characteristics of a Non-Community Water System helps regulatory agencies ensure that these systems comply with safety and health standards, facilitating proper monitoring and management.

Understanding this definition is essential for water operators, as it informs the responsibilities and compliance obligations of different water systems, enabling them to provide safe drinking water to the populations they serve.
