What characterizes a non-transient non-community water system?

A non-transient non-community water system is defined by its service provision to at least 25 of the same people over a period exceeding six months each year. This type of system is commonly found in places like schools, factories, or other workplaces where the same group of people gathers on a regular basis. As such, these systems are required to meet specific drinking water standards to ensure safety for these repeated users.

This characteristic is crucial because it distinguishes non-transient non-community systems from other types of water systems, such as those that might serve transient populations or fewer than 25 people. The focus here is on the stability and regularity of the user base, which places it under regulatory oversight for public health.

Factors like intermittent operation or serving a small, fluctuating population (as seen in transient systems) or being linked to private residence systems do not apply to non-transient non-community systems. This classification ensures that the drinking water quality is appropriately managed and monitored for a consistent group of consumers.
