Modelagem Hidráulica do Interceptor Oeste da Cidade de Fortaleza/CE

Abstract

An alternative identification of problems that has been widespread in studies and research is the use of computational tools to verify the performance of sewage and drainage networks to enable the understanding of their functioning in a proactive way, contributing to the good performance of the system and mitigating and/or avoiding occurrences of over flow and bad odor. Modeling software allows simulation of possibilities based on reality, enabling the prior identification of possible conditions that may impact the operation, contributing to a correct diagnosis and its correction with resources contributed by the Public Call Notice Funcap- Cagece. Still in partnership with Companhia de Água e Esgoto do Ceará - CAGECE, the present work aimed to analyze the hydraulic conditions of operation of the West Interceptor, located in the maritime slope basin in the city of Fortaleza – CE, understanding the possible relationship between the occurrence of overloads and overflows with the deposition of sediments in the pipeline, through hydraulic modeling performed by the software Personal Computer Stormwater Management Model – PCSWMM. Based on the simulation of four possibilities that disregard the rainy season in the municipality, critical points were identified where the interceptor works with effluent overload without the free blade for ventilation in the conduit, that can generate operational problems for the network, in addition to being indications for over flow with the influence of other external factors, such as the rain.
