An Environmental Decision Support System to Identify the Most Appropriate Wastewater Treatment Process. From Catalonia to Latin America

Abstract. To define the most appropriate process to treat urban wastewater is not an easy problem to solve. This definition represents a complex problem that requires the participation and the consensus of different agents (social, economic, environmental). In order to confront this problem, the Catalan Water Agency developed an Environmental Decision Support System (EDSS). This EDSS has proved to be a good tool to help in the planning process to select adequate wastewater treatment options. Therefore, we propose the reutilization of the Catalan EDSS in Latin American regions. This paper presents the EDSS developed by the Catalan Water Agency and a preliminary study for the adaptation of this tool in Latin American regions.
