Fontes alternativas de água em edificações: perspectivas e desafios

Abstract

The increase in population exerts significant pressure on water resources, increasing the demand for potable water, resulting in global water scarcity. Water scarcity is a global and persistent challenge, and in Brazil, despite having one of the largest water reserves in the world, there are significant disparities in its distribution. Faced with this scenario, there is a need for greater appreciation of the rational use of water, highlighting the use of alternative water sources such as rainwater, greywater, and air conditioning condensate, which are gaining prominence as economically and environmentally viable solutions. The objective of this study was to conduct a literature review and present various alternative water sources, including rainwater, greywater, and air conditioning condensate, for non-potable use in buildings, and to demonstrate their economic viability, water quality, and quantity generated by each of the mentioned modalities. This study adopts a descriptive approach, based on the review of various literature sources, including scientific articles, dissertations, theses, and books related to the subject.
