What defines a dead-end line in a water distribution system?

A dead-end line in a water distribution system is defined as a section of pipe that does not connect to other lines and may trap water. This characteristic is significant because it can lead to issues such as stagnant water, which may become a breeding ground for bacteria and lead to water quality problems. Additionally, dead-end lines can result in inadequate flow and pressure, making them less efficient for effective water distribution.

In contrast, a line that connects to multiple other lines refers to an interconnected network that promotes water circulation, preventing stagnation and ensuring better serviceability. A pipe that carries wastewater is not applicable to the definition of a dead-end line since it typically pertains to sewer systems rather than water distribution. Lastly, a temporary water supply line does not fit the definition, as it implies a line set up for a short period rather than a permanent section that lacks connections. Each of these options highlights different aspects of water systems, but only the definition of a dead-end line specifically addresses the lack of connections and the potential for water to stagnate.
