COLLECTION AND REUSE OF RAINW ATER IN BUILDINGS AS A BENEFIT FOR CITIES

Abstract

The research arises from the problems faced by cities due to heavy rainfall, and the obsolete drainage infrastructure systems, that lead to the collapse of rainwater evacuation systems. Contributing to the resolution of the problematic, with a proposal based on the collection, reused, and evacuation, through the retarders or other systems inside the property. In this way, the excess of flow that might be find in the runoff will decrease singnificantly, reducing the negative impacts on the city and granting sustainable benefits to this natural resource. We understand that non-conventional retarders are easy to combine with conventional ones, allowing to enhance their results not only at the level of urban storm drainage (possibility of absorbing 100%), but also contributing to ecological consideration (Ex: reduction in heat emission from natural roofs, with return to environments water by evapotranspiration process) and also those of a sustainable type (Ex: water recycling with collection and storage of a reserve tank). The validation is carried out from the intervention of an existing building, this allows to test the feasibility of different systems of rain regulators that is being analyzed.
