Aproveitamento de água da chuva para uso doméstico não potável : um estudo de caso no bairro de Tancredo Neves, Salvador-Bahia

Abstract

This Final Course Project presents a proposal for a rainwater harvesting system for non-potable domestic use in a low-income household located in the Tancredo Neves neighborhood, in the outskirts of Salvador, Bahia. The study adopts a case study methodology and relies on updated literature on the subject, rainfall data collection for Salvador, and the application of rainwater harvesting technology in a single-family residence. The relevance of this theme lies in rainwater harvesting as an alternative to minimize conflicts arising from water scarcity in contemporary urban areas. This work highlights the importance and potential for reducing water consumption, as well as its contribution to the preservation of water resources. However, the analysis also raised concerns about the economic feasibility of implementing and maintaining such systems in low-income households. Considering the initial installation costs and ongoing maintenance expenses, it is evident that, without external financial support or government incentives, these families may face significant challenges in sustaining a rainwater harvesting system. Therefore, although the alternative proves technically efficient and can help solve part of the daily challenges related to water supply, its viability in low-income communities depends on the creation of strategies to mitigate the financial burden on these populations.
