Abstract: Pressure Management (PM), as a key strategy for reducing water distribution networks leakage and water demand management (WDN) has commonly been a practical point of attention. While the effects of PM on the performance of WDNs have received enough attention from academics, it is often nominated as the earliest and the most practical approach in many water utilities to reduce water leakage and manage demand. Therefore, managing WDNs pressure, in a manner that can optimise water leakage while ensuring consumer demands, is an important goal. In this study, implementing PM in a WDN located near the southwest of the City of Isfahan, Iran is considered as the case study. While this network has high daily average pressure head, it suffers from high rate of leakage and unmet desired water demands. Different scenarios of PM at inlet of network are proposed and evaluated based on two objectives namely; the total WDN's water leakage and the system's water availability. Pressure Dependent Demand and Integrated Model for evaluating losses are used to simulate water consumption and pipe water leakage respectively. The results show that with minor modifications in the pressure at inlet of the network, the system's water availability and the leakage rate may be optimised. The more conformity is available between pressure variation and consumption pattern, the more advantages can be gained from PM practices
