Water is an indispensable resource for life and necessary for human development and the functioning of economic activities. Due to the distance and non-potability of the sources, through supply systems the resource is withdraw, treated and distributed for final consumption in the municipalities. In this process, leaks in the infrastructures result in losses and waste of an increasingly scarce resource, which demand is naturally pressured by the demographic expansion. In the Integrated Water Supply System of Feira de Santana, located in the semi-arid region of Bahia, despite the structural water scarcity in the region, 49% of the treated resource is lost in the distribution system, compromising service and increasing its costs. So, in face of the population projection estimated by the state statistical agencies, this paper exam the availability of water to attend the municipalities included in the System, simulating hypotheses related to the reduction of losses index of distribution under scenarios of maintenance and increased demand. The results show the already insufficient service to the population and the imperative need to improve the efficiency levels of the responsible provider, Embasa.
