Impacto da utilização de técnicas economizadoras de água aplicadas no Complexo Residencial Brisa do Lago - Arapiraca / AL

Abstract

In view of the constant use of water in the most diverse activities performed by man, with the conviction that water resources are abundant, a culture of wasting available water was created in Brazil and worldwide, with a lack of basic investments for improvements in its use and protection, and of little economic value, leading everyone to worry about the future and the actions of preservation and conservation of this resource. This work intends to estimate the reduction of water consumption in low-income residences in the Complexo Residencial Brisa do Lago, in the city of Arapiraca, Alagoas (a brazilian state) using water-saving techniques. The methodology used in this work consists of five stages: choice and analysis of the study object, consumption estimate, selection of saving equipment, study of rainwater reuse and the feasibility of implementing both systems. With the valuesfound for consumption, for the saving potential of saving equipment and for the use of rainwater, using the Neptune software, it is possible to determine the total volume of water saved in the entire complex. In possession of these values, a comparison can be made between them in order to analyze the feasibility of implementing such sustainable measures. Proposing three combinations for the implantation of the equipment in the low income houses of the complex, in which it is suggested the replacement of all the equipment and installation of the rainwater utilization system, the replacement only of the traditional equipment and, finally, the replacement only at the exit points of the bathroom, achieving savings of 65%, 50% and 19%, corresponding to each indication.
