Water networks are one of the most important elements of the infrastructure of any urban society, providing it with the most important element of modern life, which is water. Some areas and residential areas in our country suffer from water scarcity. This paper studies one residential avenue in city of Ajdabiya Libya, which suffers the problem of water shortage. An assessment, evaluation and redesign of the existing condition of the study network are executed to see how reliable is the network, how the reliability, in terms of water quantity (discharge) and pressure to raise the level of reliability, and what are the requirements to raise up the level of reliability?. Accordingly, it was necessary to develop a simulation hydraulic model of the study area network, from which the causes of water shortage are determined, and solutions are presented as well. A hydraulic solver EPANET software was used to modelling the study network from which many scenarios to overcome the shortage problem could be studied. The adopted solution was given, tested and proved its capability to overcome the water scarcity problem in the study area.
