According to standards, how many individuals must a public water system regularly serve daily?

A public water system is defined by regulatory standards as one that provides water for human consumption to at least 15 service connections or regularly serves at least 25 individuals for at least 60 days of the year. This benchmark is crucial as it determines the classifications and regulations that apply to the water system, including monitoring, reporting, and treatment requirements.

Choosing 25 individuals accurately captures the necessary threshold to qualify a system as a public water system. Understanding this number is essential for compliance with public health standards and ensuring safe drinking water.
