Estudo de viabilidade de um muro residencial sustentável para aproveitamento de água da chuva

Abstract

Brazil is a privileged country in the world due to its hydrographic wealth. However, there are regions of the country where rates of water shortage are alarming. One example is the Brazilian northeast, which faces a water crisis during most of the year. In addition, the consumption of drinking water for activities that do not require this water has grown. In this context, the main objective of this research is to analyze the feasibility of installing a sustainable residential wall for the use of rainwater in the municipality of Cabo de Santo Agostinho, as a solution for the adequate use of drinking water and a way of minimizing water shortage. For the development of this study, rainfall data were obtained from the city and the metropolitan area of Recife and dimensioned horizontal gutters and ducts according to NBR 10844 (1989). In addition, a model residence was chosen according to the socioeconomic aspects of the municipality, the costs and ways of obtaining materials from the wall were analyzed, as well as its efficiency in relation to the rainfall data of the region where the house is located during the months of the year. It is demonstrated that the sustainable wall for the use of rainwater can be feasible to be applied in Cabo de Santo Agostinho, since it presents low cost compared to other forms of vertical reservoirs, good efficiency and simplicity in its installation, providing a great shape and adequate use of rainwater.
