The study examined the water demand analysis of Public Water Supply in Municipalities using EPANET 2.0 software with the aim of providing effective planning, development and operation of water supply and distribution networks which is one of the most essential components of urban infrastructure. A number of factors ranging from population expansion to inadequate existing facilities are thought to be responsible for the frequent shortage in water supply to the metropolis. The study delineated the areas within the Municipality that are un-served or underserved by the Municipality. Using EPANET 2.0 water model software, the demand for the Underserved and Unserved area is calculated. A framework for taking management decisions such as an extension of the supply network and location of new facilities was given.

Key words: Water demand, EPANET 2.0, water allocation model,
