Is a water system serving one apartment building with three apartments and six residents classified as a Public Water Supply?

The classification of a water system as a Public Water Supply is determined by the number of users it serves and the nature of the installation. A water system is generally considered a Public Water Supply if it serves at least 15 service connections or regularly serves an average of 25 individuals per day for a minimum of 60 days a year. In the case of an apartment building with three apartments and six residents total, it does not meet the criteria for a Public Water Supply.

Since this water system serves fewer than the required number of individuals and connections, it would be classified as a private water system rather than a public one. This distinction is important, as public water supplies are subject to more stringent regulations and oversight to ensure the safety and quality of the drinking water for a larger population.
