SISTEMA DE ESGOTO SANITÁRIO: Proposta de solução para o sistema de esgoto sanitário no bairro Flora em Três Corações

Abstract

In cities benefiting from a public water supply system and still lacking a sanitary sewage system, wastewater ends up polluting the soil, contaminating surface and groundwater and often flows into ditches and gutters, constituting dangerous outbreaks of spread. of diseases. The sanitary sewage system has the main purposes related to the hygienic, social and economic aspects. Thus, this paper presents an improvement proposal for the clogging of the collecting network and direct launch at the receiving body in the Flora neighborhood in the city of Três Corações in Minas Gerais. To solve the problem, an on-site analysis of the existing network was performed and two hypotheses were proposed. For the development of these hypotheses it was also necessary to carry out a literature review on books, articles and related works in the area. After analysis of the two proposals it can be concluded that the second one is more economically viable, since it will not have an interceptor and with a smaller depth. In the proposal adopted new sections were created with cleaning terminals, inspection and cleaning tubes and manholes; After that it was possible to verify in each section the flow, the minimum diameter, the minimum slope, the tensile stress, the final velocity and the critical velocity. In the downstream section of the neighborhood was created a lifting station and a treatment station with septic tank and anaerobic filter.
