ALTERNATIVAS PARA A IMPLANTAÇÃO DO SISTEMA DE ESGOTAMENTO SANITÁRIO NO IFGOIANO CAMPUS RIO VERDE

Abstract

One of the services that basic sanitation aims to provide is the collection, removal and treatment of sewage, as when sewage is disposed of incorrectly it can cause the proliferation of diseases. To meet this requirement, collective enterprises must have sewage systems within their property, with implementation and maintenance being their responsibility. Over the years, the population of Rio Verde increased, as did the demand for the IFGoiano campus, however, there was little updating in the campus's sewage system, which still has an old ceramic network and rudimentary septic tanks which , in addition to not meeting current demand, it contains cracks and degradation and is possibly contaminating the soil. The campus' water supply comes from underground, which makes it extremely necessary to avoid contamination of groundwater so that it does not lead to diseases caused by ingestion. Other problems are the proliferation of vectors, the spread of diseases and the bad smell. To be able to resolve the issue of campus sewage, there are some possible alternatives for updating the sanitary sewage system. One of them is to establish a new collection network that will be interconnected with the city's existing public network. Another option would be to sector sewage into decentralized systems with the joint application of septic tanks and wetlands. Therefore, this work aims to propose suggestions for adapting the sanitary sewage system of the IFGoiano Rio Verde campus to serve the people who frequent it, as well as analyzing the economic viability of each proposed sewage management alternative. Regarding the technical aspects, it is highlighted that the centralized network has a more widespread standardization, however the execution is difficult as it must be done completely, whereas the decentralized network does not have a more widespread standardization, but the execution ends up being easier due to the possibility of being carried out in stages. Regarding the economic aspects, it was possible to observe that the centralized network is a system with greater user reliability, however, more expensive, totaling an execution cost of R$ 1,849,549.35. The decentralized network is a system that is not yet as popular, but less expensive, totaling an execution cost of R$1,382,480.23. In addition to these values, the centralized network has an estimated operating and maintenance cost of R$ 13,187,424.57 over 20 years, which makes the choice for this alternative unfeasible, as the operating and maintenance costs of the decentralized network are of R$44,697.60.
