Potential gains from the implementation of filtering gardens for the reuse of greywater in public buildings

Abstract

Water is an indispensable resource for the survival of every living being, treated for many years as an inexhaustible source. However, the growth of the world population, and the uncontrolled consumption of natural resources, brought several environmental problems, in particular the scarcity of drinking water for a considerable portion of the population. The reuse of wastewater gains more and more importance, in view of a more sustainable cycle of water in the urban environment. In Brazil most of the (ETE) have limitations regarding the removal of pollutants. The objective of this study was to present measures to mitigate the damage to the environment and conservation of natural resources, with the reuse of water through the implantation of a Filtering Garden in the public building of the Desembargador Henrique Capitolino Forum in Jaboatão dos Guararapes - PE. This work is configured in a research of mixed method - procedure of collection, analysis and combination of quantitative and qualitative techniques and through bibliographic means, from the legal literature. The results of the research are in line with the direct contribution to the PLS goals established by the CNJ, contributing to the sustainable development objectives. Through the reuse of gray water in the building with plants, called macrophytes, through new technologies in filtering gardens, demonstrated a payback of less than one year and with the implementation bringing several environmental, social and economic benefits. The socioeconomic profile or level of education did not show a correlation with environmental concern, so it is important to consider the need for investment and more effective communication regarding environmental issues with those who are part of the Judiciary in Pernambucano.
