What are public water systems primarily defined as?

Public water systems are primarily defined as water supply systems that serve the public. This includes any system that provides water for human consumption to at least 15 service connections or serves at least 25 individuals for at least 60 days a year. These systems are regulated under various health and safety regulations to ensure the quality and safety of the drinking water provided to communities.

The importance of distinguishing public water systems from other types of water supply is rooted in the obligation to maintain quality standards and ensure accessibility for the greater population. Public systems are held to rigorous testing and reporting standards that are essential for maintaining public health.

Other choices refer to specific types of water sources that do not provide water primarily for public consumption. Systems serving individual homes relate to private water systems, while private residential supplies indicate water sources that are not regulated as public systems. Irrigation water systems for agriculture are also not designed for human consumption, illustrating that they serve a different purpose compared to public water systems.
