Abstract
Water distribution networks face a pressure-deficient condition during component failure and during the addition of fire-fighting demand. Prediction of performance of water distribution networks under pressure-deficient conditions is important for network design. The demand-driven analysis method did not have the ability to simulate the pressure-deficient network, and hence many pressure-driven analysis methods have been developed. A simplified revised method to analyze the pressure-deficient condition of water distribution networks was developed and is reported here. The revision reduces the number of artificial elements added to the demand nodes for simulating the pressure-deficient condition in a single iteration. A new resilience indicator was developed and applied to a network to demonstrate its application to pressure-deficient networks. Estimating a meaningful resilience performance was facilitated by the new indicator.
