Which type of water-supply pipe is designated for public use under the jurisdiction of public authorities?

The designation of water-supply pipe for public use under the jurisdiction of public authorities is the Public Water Main. This type of pipe is specifically designed to transport water for municipal or community use, ensuring that it meets safety and quality standards set by regulatory agencies. Public Water Mains are typically the larger pipes found underground that distribute treated water to homes and businesses within a community.

Public Water Mains are subject to regulations that ensure they are built and maintained properly, providing safe drinking water to the public. They are distinguished from private lines, residential lines, or shared pipes, as these alternatives either serve individual properties or smaller groups rather than the broader public. Understanding this distinction is critical for compliance with plumbing codes and for promoting public health and safety in water distribution.
