What does a "dead end" refer to in a water distribution system?

• A. A section of pipeline with continuous flow
• B. A section of pipeline that has no flow or outlet
• C. A section under construction
• D. A section designated for future expansion

Answer: (B)

In the context of a water distribution system, a "dead end" refers to a section of pipeline that has no flow or outlet. This situation typically arises when a pipeline terminates without connecting to another line or water source, causing water to sit stagnant at the end of the section. This stagnation can lead to water quality issues, as the water may become stale, potentially promoting the growth of bacteria or other contaminants. Additionally, dead-end lines can complicate system flushing and maintenance activities, making them important features to manage carefully in a distribution network. The other options describe different conditions within a water distribution system but do not accurately represent the characteristics of a "dead end." Continuous flow, construction areas, and designations for future expansion involve active water movement or planned modifications, which are distinct from the stagnation found in dead-end sections.
