Abstract

According to Máximo and Darli (2017), the construction industry, despite being an important sector for the Brazilian economy, can be considered one of the areas that cause serious impacts to the environment, since it allows the generation of a lot of waste and the great use of natural resources, including water that is indispensable for life. To reduce the negative effects of civil construction on the environment and may have the possibility of generating less costs for residents of affordable housing, who are affected by the country's social inequality, the use of rainwater can be a good option. According to Mierzwa et al. (2007), the reuse and use of water presents itself as an attractive option for minimizing the effects of water scarcity and costs, while part of the water consumption will be from renewable sources that, in turn, can affect considerably on the final price of sanitation services and, consequently, mitigation of the exploitation of this indispensable natural resource. Therefore, the objective of this work is to carry out an analysis of a project of a popular residence in Goiânia-GO, as well as the calculations, aiming at a proposal of a new system, considering the implementation of a System of Utilization of Rainwater, in line with environmental and economic viability. As a final result, there was an economic and environmental compensation for the modified project of the low-income residence due to the reuse and use of rainwater.
