Aproveitamento de água da chuva em bloco de condomínio: estudo de caso em Naviraí/MS

Abstract

In view of the problems of the shortage of potable water for consumption and the aware use of water, it became a matter of interest.. Furthermore, with the increase of cities, the percolation of rainwater has decreased, due to the increase of impermeable areas. Thus, there is a need to develop sustainable ideas that use rainwater for non-drinking purposes. The purpose of this task is to dimension and analyze the economic viability of implementing a rainwater reuse system to supply the toiletsl of a residential building with water from rainfall. The research was developed at Residencial Nelson Trad, with 800 apartments, located in Jardim Paraíso IV at Naviraí, using the Rippl's Method. The results confirm the efficiency of the capture, reservation, supply and distribution system, which may provide savings of 16% in relation to the average monthly consumption per apartment, estimated at 2.9 m³ of potable water, resulting a economy estimated of 2,320 m³ at the 800 apartments of the condominium residential.
