What is the defining feature of a community water system?

The defining feature of a community water system is that it serves at least 15 service connections year-round. This specification ensures that the water system is designed to provide a consistent supply of water to a stable population, encompassing residential users and potentially some small businesses. The 15 service connection threshold indicates a level of demand and infrastructure that distinguishes community water systems from other types, such as transient or non-community systems.

This definition is important for regulatory purposes and helps classify water systems appropriately, ensuring they comply with health and safety standards necessary for long-term service and reliability. In contrast, other options, such as serving only transient populations or being exclusively non-profit, do not accurately capture the essence of a community water system, as community systems are primarily focused on serving a stable and permanent population. Additionally, the requirement of having a public park does not pertain to the functionality or classification of a community water system.
