Proposta de alternativa sustentável para o sistema de esgotamento sanitário da expansão do campus da Universidade Federal de Goiás em Aparecida de Goiânia – GO

Abstract

In its expansion project, the Federal University of Goiás (UFG) implemented a campus in the municipality of Aparecida de Goiânia (GO). Located four kilometers from the urban area, the location does not have access to centralized treatment of domestic effluents. In this sense, this study aims to propose a sustainable and environmentally viable alternative for a decentralized domestic effluent treatment system. Initially, literature reviews and reviews of relevant regulations were conducted. The specific characteristics of the location and the characteristics of potential alternatives were analyzed. The potential alternatives were cataloged and parameters for the selection of decentralized systems were defined. Therefore, two interventions in the sanitary sewer system were proposed: the first, as a more conservative proposal, involves the combination of a septic tank followed by an anaerobic filter. The second proposal involves the combination of a RAFA/UASB reactor followed by an anaerobic filter. Thus, in accordance with the United Nations Sustainable Development Goals (SDGs), an alternative efficient sanitation system was found from an environmental perspective and that aligns with the Institutional Development Plan of the Federal University of Goiás (UFG), which guides the infrastructure and sustainability policies within the institution.
