Bmp in Brazilian Cities - Standardization and Application (PAP014834)
Alessandro Mendes Ribeiro, Podalyro Amaral de Souza
The problems with the floods in large urban centers is a recurring theme for the technical community and, also, one of the greatest challenges, hence the solutions are becoming ever more difficult and expensive than what they would be had there been the presence of planning prior to the occupation. In these metropolis, the main road system is consolidated in the lowland areas along the major rivers, thus resulting in large-scale material losses and in other non-measurable losses as well, such as the loss of lives.Apart from the impact of the sealing of ground surfaces - in which large volumes are generated over a short period of time - the quality of the water is worthy of regard. In addition to the material carried by the water drag, there is a large amount of contaminating agents, which compromise the treatment and the self-purification of the bodies of water located downstream from these points. In the system of conventional drainage, there is no concern for the reduction of the peak waves and, likewise, for the quality of the water, whilst, in many cases, the problem is pushed on to the smaller-sized municipalities that have no conditions of affording protective measures.These concerns have led the technical community to rethink the conventional system of drainage and to seek ever more sustainable solutions, with a focus on reducing the massive impact of the storms whilst trying to minimize the concentration of pollutants in the waters. The great challenge lies in the feasibility of deploying those techniques in locations that are densely populated and with few spots available for the implementation of these solutions.The standardization of the nomenclature and the classification of these methods is proposed, with aims at making them more accessible to the technical community, making them more applicable, and trying to support and disseminate such concepts based on the international bibliography, whilst adapting them to the Brazilian reality.An example of application with the use of the techniques in a consolidated urbanized area has been provided in an effort to demonstrate solutions which adapt to the midst and, at the same time, promote environmental and urban improvements for the city.
