Análise ambiental e financeira da utilização de aparelhos poupadores de água nas residências da cidade de São José de Piranhas-PB.

Abstract

The availability and quality of freshwater in the world have been steadily declining in recent years, mainly due to the increase in demand, mainly urban, coupled with problems such as waste and pollution of water sources. Nevertheless, the lack of adequate planning policies for the use of water resources is a factor that contributes to a large population that does not have access to good quality water. At a time when water conservation is critical, it is necessary to seek sustainable measures and solutions that contribute to the rational use of water. The implementation of water-saving appliances in existing buildings can significantly reduce water consumption. Therefore, this work was developed with the purpose of analyzing the reduction of water consumption and the financial savings resulting from the replacement of conventional hydrosanitary appliances with water saving appliances in the residences of the city of São José de Piranhas - PB. It is hoped that these parameters can serve as a support for urban planning, helping to establish incentives to minimize water consumption. In order to do so, four types of saving mechanisms were selected, and 10 possible scenarios were proposed for the implantation of these devices, evaluating the implementation costs, the reduction in water consumption and the financial return on investment. The results indicate that the use of the saving equipment reduces the final consumption of water in each residence, reducing the final value of the water bill, but the time of return of the investment for the implementation of the saving device, in certain cases, can be considered high (More than 2 years). It is concluded that it is possible to reduce water consumption, using instruments that contribute to the rationalization of its use, since actions of accountability of society for the conscious consumption of natural resources have proved effective, adding quality to urban areas. It is hoped that these parameters can serve as a support for public policies, helping to establish incentives to minimize water consumption.
