Proposta de metodologia de simulação integrada das redes urbanas de drenagem pluvial e esgotamento sanitário

Abstract

The "Separate sewage system" is legally adopted in Brazil - sewage and stormwater flow in two separate systems. However, in this country, the separate sewers do not demonstrate the functionality foreseen in their project. There are many irregular crossed contributions between systems, characterizing a mixed dysfunctional system. It is worth mentioning that sewage collection is fundamental to guarantee the sanitary conditions of the residences, but its simple collection, without treatment, is the central factor for environmental degradation. Thus, the need to analyze the joint functioning of the two systems is crucial for the proper management of the presented problems. This way, mathematical tools that allow a correct and integrated diagnosis and prognosis are fundamental. However, few tools to jointly evaluate these two systems are available to municipal professionals or public and private companies. Therefore, the present work aims to propose an integrated simulation methodology of urban stormwater and sewage systems for several real cases considering the possible reciprocal interferences between systems. In this way, the present work aims the development for an integrated simulation methodology of the urban networks of rainwater drainage and sanitary sewage for several real application cases, considering the crossed interferences between the two systems and the urban plan, using the cell model quasi-2D, MODCEL
