Estudo de caso da viabilidade técnica e econômica do projeto de implantação da linha de recalque da sub-bacia de Jaboatão dos Guararapes - PE

Abstract

Sewage pumping stations aim to transfer sewage from a lower level to a higher level. Located at low points, they are equipped with hydraulic pumps and increase the pressure in the liquid. In view of the high costs related to the construction, operation, maintenance, conservation and guarantee of the system's functioning, they should only be built when depletion by gravity is not possible or recommended. When it is a single possible solution, the technical and economic aspects must be taken with more caution from the conception of the project. Among them, the material to be used in the repression line, which although the most used are ductile iron (FºFº) and polyvinyl chloride (PVC), high density polyethylene (HDPE) is on the rise in the Brazilian market. Taking into account its growth in recent years, more specifically in the last decade, as well as its technical and economic parameters, one must find the best technical and economic solution to be adopted for the implementation of the repression line of a pumping station. sewage from a sub-basin in the municipality of Jaboatão de Guararapes - PE.
