Abstract

The performance of water distribution networks (WDNs) is occasionally affected by planned (system maintenance) and unplanned (fire events and main bursts) interruptions. There is always a need for water companies to study the impact of these potentially pressure deficient situations on the WDN's level of service in a realistic and practical manner. In reality, such events occur over a period of time and are usually modeled using extended period simulation (EPS). This paper presents an EPS model capable of assessing the network performance effectively and accurately under these conditions. The proposed extended period simulation model is based on pressure driven analysis (PDA) and is capable of obtaining the accurate nodal pressures and actual flows delivered at demand nodes. Simulations on the “Anytown” network were carried out to demonstrate the capability of the model. Results obtained highlighted the superiority of PDA over DDA in simulating pressure deficient networks.
