Abstract
The objective of this work is to present a bibliographic review, the subject of which is the reuse of water by rain, as well as the reuse of gray waters in a single-family residence. For this, the methodology constitutes a search for information in books, magazines, articles, master’s dissertations and doctoral theses. To consciously reuse, ways to capture water from a residence, whether from the rain that falls on the gutters or used in the methods of capture in the kitchen sinks and/or tanks of service areas that will receive the necessary treatment and will be reused. These treatments act efficiently and provide the use of this water for less noble purposes which makes consumption more rational and economical, cooperating for the maintenance of environmental resources. Keywords: Water, reuse, capture, treatment, residence.
Highlights
As Zampieron (2005) states, water has become a common symbol of humanity, valued in all religions and cultures, a symbol of social equality, because the water crisis is, above all, distribution, resources and in its absolute scarcity
The systems are scaled for rainwater and for the reuse of gray water, and the economic analysis is performed to determine the viability of the implanted systems
After the correction made through the sensitivity methods, the place where the highest water consumption was the shower with 32.8% of the total consumption of the residence, followed by the toilet with 30.4% and the kitchen tap with 28.0%, according to Table 01
Summary
As Zampieron (2005) states, water has become a common symbol of humanity, valued in all religions and cultures, a symbol of social equality, because the water crisis is, above all, distribution, resources and in its absolute scarcity. With the clear objective of reducing water consumption, through new technologies, the development of several rational use programs began. These associated problems corroborate the discussion of the feasibility of making the use of rainwater and gray water for fundamental activities in a residence. This possibility of reuse will certainly result in the decrease in the consumption of treated water that is provided by sanitation companies, in addition, there will be a decrease in the demand for costs with the use of drinking water and the reduction of risks arising from floods in periods of heavy rains. The entire basis of the work was found through information in books, magazines, articles and master's dissertations, in which the authors as well as researchers in the area, laboratory and academic research was used to support their results
