Which of the following is a measure to reduce water loss in the distribution system?

Conducting leak detection surveys is an effective measure to reduce water loss in a distribution system. These surveys involve systematically inspecting pipes and other components of the water distribution infrastructure to identify leaks, which can be otherwise undetectable but result in significant water loss over time. By identifying and fixing leaks, a utility can improve system efficiency, conserve water resources, and potentially lower operational costs associated with lost water.

In contrast, limiting the number of hydrants could potentially restrict fire protection and emergency use, which is not a sound approach to managing water loss. Reducing pressure throughout the system might lead to fewer breaks or leaks in some cases, yet it can also risk poor water service and insufficient pressure for customers, which is detrimental to overall service quality. Decreasing customer awareness campaigns would not contribute to reducing water loss; instead, it could lead to increased wastage if customers are not informed about the significance of conservation and efficient water use. Overall, conducting leak detection surveys directly addresses the issue of water loss through proactive identification and remediation.
