RESUMO

In the rainy periods, the city of São Paulo becomes a scenario for constant social and economical impacts before the damages caused by the inundations. This fact is associated, among other reasons, to an expressive land occupation and soil water-sealing and to the occupation of the areas under risk of inundations the meadows and bottoms of valleys. The research below analyzes the different concepts for handling pluvial waters under the scope of reflections relative to the infrastructure works and public actions addressed to prevent inundations. We tried to present the hygienist vision regarding the increase in water conductivity up to the new environmental vision of sustainable rain water handling, highlighting the use of non-structural measures. For such an effect, we used as case study the Basin of Córrego Cabuçu de Baixo located at the northwest area of the city of São Paulo that, for a long time, was object for punctual interventions with predominance of canalization works and, in the end of the nineties, it counted with the implementation of non-conventional measures that took into account the planning of land occupation and the reservation of pluvial waters. Through the evaluation of this experience we look for identifying the permanencies and ruptures in the treatment related to the subject of inundations.
