Abstract— The reuse of water from air conditioners has proved to be a valuable alternative to the water waste promoted by the excessive use of drinking water in activities that would not necessarily require clean water, such as washing external areas and windows. In this sense, the general objective of the present work is based on evaluating the thematic pertinence of the adequacy of the network implementation for the reuse of water from the dripping of the Forum Lourenço José Ribeiro (Fórum de Olinda) air conditioners, an organ that is part of the Tribunal of Justice of Pernambuco, located in the city of Olinda/PE. The case study is shown as a sufficient methodological apparatus to obtain results, which were evaluated through qualitative and quantitative techniques, intending to achieve a correct understanding of the cost savings with the implementation of drip water treatment of air conditioners in this building that is part of the Pernambuco Court of Justice. Results obtained indicate that the alkalinity of the water from the air condensers could not be used for human consumption, but it is suitable for use in non-noble purposes, such as washing the Forum patios. With this, the reuse of water resources resulting from the dripping of air conditioners is efficient to promote the yield of a natural asset that needs to be used within its maximum capacity, through the appropriate treatment that allows the reuse of the hydric matrix. I. INTRODUCTION The imminence of the Earth's most precious natural resource impoverishment puts society in a position to seek efficient alternatives for maximum use of what is available for human use. In this perspective, there are studies that seek the reuse of potable or non-potable water that were discarded in residential, industrial, business and agricultural environments. According to Sousa et al. (2021), the reuse of water, as well as its use, as they are reputable and reliable procedures, have been established as one of the most beneficial alternatives for saving water. Among the water resources commonly discarded, the reuse of condensed water from the dripping of air conditioners could guarantee the reduction of a certain use of drinking water and contribute to the sustainability that has been revealing itself as the great promoter of the balance between the environment and humanity (CORDEIRO, 2019). Taking into account the immense human population and the scarce percentage of fresh water available in the world – in addition to countless other examples that indicate the increasing decrease of natural resources available in nature – human society needs to adapt
