Acesso em:.https://repositorio.ufpa.br/handle/2011/6054One of the main barriers to expansion of sewage system in the country is the high cost of implementation of sewage disposal system, as being directly related to depth. Considering this problem, this paper presents two different studies tracings collection network type absolute tab for the city of Santa Cruz Arari - Marajó - Pará, in order to find the smallest depth and consequently the best cost. First, we designed two stroke sewage disposal system in the area with the highest population concentration is scaled according to existing technical standards. From the quantitative surveys of each stroke, there were budget spreadsheets with the possibility to compare among themselves the best network cost. Although there was little difference in length between the two paths, the item is weighed more than the depth of the network along the stretch of arrival of Sewage Pumping Station, for example, the depth was 4.90m and 4.77 m for the Path 1 and Path to 2, respectively. Soon we had the best total cost was Trace 2, with a total value of R$ 908,329.11 versus R$ 1,021,818.11 in Trace 1, representing a savings of R$ 113,579.00 to the same location. According to the results obtained, it was possible to evaluate the study tracing sewage disposal system becomes important for any location, as in this case study, where the city presents great difficulties of access and reduced costs for system implementation sewage.porAcesso AbertoRede de esgotosTraçadosCustoProfundidadeSewage disposal systemsTracingsCostCostDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA SANITARIACNPQ::ENGENHARIAS::ENGENHARIA DE PRODUCAO::ENGENHARIA ECONOMICA::ANALISE DE CUSTOS
