Why is it crucial to flush dead-end lines in a distribution system?

• A. To improve aesthetic appeal
• B. To enhance the pressure in the system
• C. To ensure proper water turnover
• D. To remove harmful sediments

Answer: (C)

Flushing dead-end lines in a distribution system is essential primarily to ensure proper water turnover. Over time, water sitting stagnant in dead-end lines can lead to lower water quality due to a buildup of sediments, lack of oxygenation, and potential bacterial growth. By regularly flushing these lines, fresh water replaces the stagnant water, effectively promoting movement through the distribution system. This turnover helps maintain the overall integrity of the water supply, ensuring that consumers receive clean and safe drinking water. Improper turnover can also result in aesthetic issues and undesirable tastes or odors, but the primary focus is on maintaining water quality and safety through adequate circulation.
