Why is it important to install a sufficient number of valves on a water pipeline?

• A. To minimize the number of customers affected by an outage such as a main break
• B. To eliminate air pockets
• C. To decrease head loss
• D. To minimize the number of hydrants required

Answer: (A)

The importance of installing a sufficient number of valves on a water pipeline is primarily tied to operational efficiency and customer service. When there is a main break or any type of outage, having a well-placed valve system allows operators to isolate the affected section of the pipeline. This means that they can shut off water flow only in the areas directly impacted by the break, thus minimizing the number of customers who experience a water outage. The quicker and more efficiently the situation can be managed, the less disruption there will be to the community. Valves also play a crucial role in regulatory compliance and maintenance operations, allowing for quick repairs without needing to shut down water supply to larger areas. While other options mention concerns like air pockets, head loss, and hydrant requirements, those are not the primary reasons for needing a sufficient number of valves. Instead, the ability to isolate problems and keep service interruptions localized is the most critical function of valves in a water distribution system.
