Deposição irregular de resíduos de construção, demolição e a drenagem urbana: caso Córrego Capim Puba - Goiânia, Go

Abstract

The urban drageing is composed of the flow directing devices and the water courses that receive it. Old ones are the problems of floods and inundation verified, but the perception of the exhaustion of the system, as a whole, is recent and has demanded specific studies for solutions to recurrent and urgent problems in urban centers. The barriers to solution are diverse, such as population density in the waterproofing of green areas, irregular occupation of preservation areas, obstruction of the system by residues, and the lack of environmental education of the population in general. The research presented here is a case study in Córrego Capim Puba in Goiânia, which aimed to verify the relationships between the irregular deposition of residues in the margins and the consequent loss of quality of drainage, which generates floods in the region. Points were collected for the irregular disposal of solid waste on the banks and bed of the Córrego Capim Puba, through a technical visit to the site, using GPS in 2013 and 2018. A comparison was made with the data collected in the two years used as reference and it was verified that, despite the social concern and the damages caused by the flood, that there was an increase in the accumulation of deposited waste, including by the residents themselves who are affected by the floods, sewer discharge points, irregular drainage of water from sources, obstructions in the drainage system, narrowing of the stream channel, demonstrating the urgency of promoting public policies that more effectively manage rainwater.
