Comparação de diferentes materiais no projeto de uma rede coletora de esgoto para o Município de Água Santa - RS

Abstract

Over the years, basic sanitation has become a right of the population, making it mandatory to to provide a sewage system for the buildings. However, many municipalities, especially small ones, still lack this system, disposing of sewage incorrectly, resulting in the emergence of various diseases. Thus, the present work aimed to identify how sanitary sewage occurs in the municipality of Água Santa - RS, through the Municipal Plan for Basic Sanitation and the website of the National Agency for Water and Basic Sanitation, and, subsequently, to dimension a collection network, call of sanitary sewers system, for part of the municipality through conventional methodologies. In addition, the sizing of the same collection network was carried out using the 100% PVC system, and the calculations and sizing of the project were carried out with the aid of AutoCAD software and Microsoft Excel, and, finally, a comparison of the different materials used and cost evaluation. The study area was determined using ArcGIS and Global Mapper software, where the contribution basins of the urban area were delimited and the basin with the highest number of economies was chosen for the design of the collection network, while the population projection was carried out through data from the Brazilian Institute of Geography and Statistics (IBGE). As a result, it was concluded that there is no sewage collection network in the municipality and that part of the urban population disposes of it incorrectly. Still, in the sizing, it was verified that the collection network with 100% PVC technology, becomes more technically and economically viable.
