ABSTRACT
ABSTRACT: Failures within Water Distribution Systems are inevitable and their effect results in reduced levels of service. The reduction in levels of service can be obtained through simulation, however it is important that when simulating these failures an appropriate analysis method is available. Traditionally failures in water distribution systems are simulated using demand driven analysis, that is not appropriate for extreme events in the network. A more appropriate analysis approach is pressure dependent demand one. The paper highlights the way a demand driven analysis distorts the performance of the network during failure and hence predicts the levels of service incorrectly.
