Leak detection and quantification of losses in a water network

This article demonstrates an approach for quantifying leakage and pinpointing the location of leaks in water networks. It presents the methodology and discusses the results of an experimental field study that was undertaken in three areas of Riyadh, Saudi Arabia. The experience from this study indicates that the most accurate method for determining leakage rates is by direct measurement of net night flow. In the alternative, commonly‐used method, the net night flow is computed by reducing the minimum night flow by an assumed water consumption for properties at night. This is inappropriate for use in water networks like that of Riyadh, where the practice of water storage at consumers’ premises is a predominant feature of the water supply system.
