Las desigualdades en el acceso al agua en ciudades latinoamericanas de rápido crecimiento: El caso de Arequipa, Perú

Abstract

Cities in developing countries are going through an unprecedented process of urbanization that is reconfiguring their water supply systems. On the one hand, urbanization favors the expansion of formal water networks but on the other it also must resort to informal practices (pipe trucks, public pylons, etc.) especially in peripheral settlements. Using survey and secondary data for center and the periphery of Arequipa, Peru, we contrast the provision of water services by the two systems through the characterization of accessibility, availability, quality of service, price and preferred management model (public or private). Results indicate that networked supply systems in peripheral areas increase accessibility, but perform worse in terms of availability, quality of  service and affordability. Although to a lesser extent, these problems are also present in the networked formal city regarding interruptions of service and prices. In peripheral areas informal systems remain precarious potentially generating unfavorable long-term effects. Hence, difficulties in access to reliable, safe and affordable water are observed in both contexts although the current public management system is preferred to private management.
