Estudo de custo de linha de recalque de esgoto sanitário, em função do tipo de tubulação e do solo, no estado de Goiás

Abstract

Access to basic sanitation is not a reality for 60% of the population of Goiás. In this sense, one of the main obstacles is the high cost of implementation, which can be solved by applying materials that effectively meet the needs, but at a low cost. For this, the choice of materials adopted depends on a cost-benefit analysis. In the discharge line and other linear units of the sewage system, there is a predominance of ductile cast iron (FoFo), polyvinyl chloride (PVC) and high density polyethylene (HDPE) materials. However, it is necessary to analyze the cost of the whole process for the implementation of the booster line. Focusing on the fact that the pipe material and the type of soil prevailing in the location directly interfere in the configuration and characteristics of the trench. Due to the possibilities that exist depending on the variables presented, a study was carried out, per meter, of the total value of implementing the pressure line. It was possible to conclude that the most advantageous economic option for the state of Goiás was PVC/DEFOFO carried out on 1st category soil.
