Aplicação de metodologia de análise hierárquica (AHP) para priorização de intervenção em estações de tratamento de esgotos - Estudo de caso na Bacia do Siqueira, Fortaleza/CE

Abstract

The reality of Ceará’s sanitary conditions is still precarious, mainly on sanitary sewage, causing direct impacts on the environment and its surrounding communities. One of the main challenges is the management of the already existing sewage treatment units. Before that, the purpose of this case study is to propose a multicriterial methodology that supports decision which prioritizes interventions to the Wastewater Treatment Plants (WTP) of the Siqueira basin, located in Fortaleza - CE. The chosen method is the Analytic Hierarchy Process (AHP), which works with the hierarchical problem and allows to correlate many alternatives and criteria. Despite the sensitivity of the method to variations of value judgment made by the decision makers, the practicality of the research is achieved, given that the proposed methodology is based on criteria of facilitated reproducibility, which will allow actions by the licensing agencies and inspectors of the activities of an WTP or by the local sanitation company itself in order to eliminate or mitigate possible identified nonconformities.
