The development of urban distribution networks in the South is often carried out by agents of the North and analyzed under the financial and operational indicators used also in the North. Using the results of a case study in a small urban centre in Ethiopia, we propose a different evaluation model to measure the efficiency of such implementations across the concepts of Sustainable Urbanization. GIS maps are used to analyze the evolution of urban basic services, the dynamics of population movements and economic changes. With those results we can address the social dimension of inequality and exclusion that should be considered in the design and planning of water networks. The aim is to reduce the risk of slums formation and to promote inclusive growth in services.
