Which statement best explains the term "water main"?

The term "water main" refers to a large pipe that is essential for the municipal water supply system. It is designed to transport potable water from treatment facilities directly to distribution systems. This role is critical because the water main serves as the primary conduit through which treated water travels before it is delivered to individual homes, businesses, and other facilities. It functions at a larger scale compared to pipes that serve smaller distribution roles, such as those that connect directly to homes. Understanding this definition illustrates the importance of water mains in ensuring that communities have access to safe, clean water. Other options do not capture the specific purpose and scale associated with a water main.
