Identify a method for detecting a water leak in a distribution system.

Monitoring water pressure and flow rates is a highly effective method for detecting water leaks in a distribution system. By regularly assessing these metrics, it becomes possible to identify irregularities that may indicate the presence of a leak. For instance, if the water pressure drops significantly without any corresponding changes in demand, or if flow rates are higher than expected, this could signal that water is escaping through a breach in the system.

This approach is advantageous because it provides quantitative data, which can help in pinpointing the location of the leak based on discrepancies in the readings compared to normal operation. Other methods, such as visual inspections or listening for sounds of running water, might not be as thorough or reliable in detecting small or hidden leaks that do not produce noticeable symptoms. Checking for ground saturation alone may provide some indication of a leak, but it is generally a secondary effect rather than a direct measure of water loss from the distribution system. Thus, monitoring water pressure and flow rates gives a proactive and systematic approach to leak detection.
