Proposição de sistema de captação e reservação de água pluvial para usos não potáveis como componente de projeto padrão de habitação de interesse social: estudo de caso de empreendimento em Cornélio Procópio/PR

Abstract

The buildings for low-income populations, also known as social housing, are part of public policies which aim beyond to make up the housing deficit, but to guarantee the access to basic rights and human dignity. So, it’s extremely important that these buildings compose integrative programs, which consider the impact that the new buildings cause – to the environment and to the city. To implement elements that support the housing efficiency about water and energy consumption, and that reduce the impact over the urban systems and the environment represents steps toward this integrative mindset. This paper evaluated the viability of setting a rainwater harvesting system, to non-potable ends, in unities of a social housing program, that consists in a condominium with townhouses reserved to elderly people, in the city of Cornélio Procópio, in Paraná’s north area. It was possible to see that the area presents good rain rates, with average precipitation over 100mm per mouth. Nonetheless, the ideal storage volumes to guarantee the supply over the hole year, took from the Azevedo Netto’s method, showed up very high, due the drought periods. The designed system considered, than, tinner reservoirs, with 400L. The system ended up being viable and able to generate positive impacts to the habitants and to the environment, helping to reduce the runoff flows in rain events.
