Resumen
The gradual increase of the world population has triggered several problems related to the preservation and availability of water resources. Given this, it is of great importance that sustainable water use and supply practices be adopted and disseminated to guarantee the water availability of this generation and the next. The aim of this work is to adopt one of these practices for the rational and sustainable use of water, implementing a rainwater harvesting system at the Lar Infantil Sol Amigo institution, in Curitiba. The institution object of this study counts with 34 inhabitants and consequently with high costs in the water and sewage tariffs, thus, this fact presents a great incentive to the implementation of a rainwater harvesting system. Therefore, in this study, data were collected on the number of inhabitants, bills for water consumption and surveys of projects to obtain the existing facilities in the buildings. The institution’s representatives were interviewed in order to carry out the project according to their interests and limitations. According to the supply and demand values of water, the design parameters were determined using the software “Netuno”. The program generated the capacity in litters of the reservoirs to be used, the percentage of replacement of drinking water by rainwater, the percentage of days that the water demand is served. After a research of Market, the software generated the economic analysis of the system, which determines the time of return of the project. Therefore, two different scenarios were presented, the first with partial replacement of toilet water and the second scenario only for washing floors and vehicles. However, the scenario 1 was the most advantageous, with a return time of 6 years and 9 months per house, proving that its adoption, in addition to being a sustainable practice, has the potential to contribute to reducing the institution's future expenditures with water consumption.
