Resumo:
It is a Brazilian reality that basic sanitation has not been proportionally following the population growth. The urban drainage system, suitable only for rainwater, has been used to transport sanitary sewage, which draws attention to the fact that this system does not have the necessary characteristics for the treatment of sewage, thus not providing adequate disposal and treatment of this type of fluid. What happens in the Prado channel, located in Campina Grande-PB, is an example of the inappropriate use of this system. For a real diagnosis of the pollutant load circulatin in the Prado Canal, it is important to determine the flow of the sewage contribution, for which the number of inhabitants of the region of contribution to these points is collected through the data of the census tracts. From the above, the present study proposes, as a general objective, to determine the flow of sewage destined for the Prado canal in different stretches within the Catolé neighborhood, Campina Grande-Paraíba. Through the population of the census tracts of 2010, the population that contributed with sewage to the canal in 2000 and in the Catolé region was stipulated. This was made possible through geometric methods of population stipulation. With this obtained population, the data of sewage flow was generated in stretches of greater relevance of the channel. The results showed that the Prado canal is being used to transport sanitary sewage. This sewage has a growing annual flow, around 18%, over 30 years. In this way, this sanitary sewage is degrading the physical conditions of the canal and damaging the quality of life of the people due to the odor produced by the canal, as well as polluting the Prado river, in which the Prado canal empties.
