Changing paradigms in water and sanitation services in Argentina: towards a sustainable model?

摘要

Within a very short period of time, the Buenos Aires metropolitan region has implemented a number of different water and sanitation service models: a federal welfare model (Obras Sanitarias de la Nacion, OSN, created in 1912), a regional decentralized model (1981), concessions to the private sector (1993), and a new public organization (2006). Analysis of various facets of the sustainability of this new organization in Argentine cities demonstrates that it seems to approach the OSN model, but with territorial limitations and some features inherited from the "private parenthesis", such as institutionalized regulation and social control of services.
