Projeto para captação, tratamento e aproveitamento de água da chuva

Abstract

With the current scenario of water scarcity, the search for systems of rational use of this resource grows. The use of rainwater is an important way to promote sustainable development. This monograph had as main objective to promote a study of the viability of the treatment and utilization of rainwater, and execution of a project for Capture, treatment and use of rainwater in a residence in the municipality of Pará de Minas. In addition, the system is sustainable and environmentally friendly, and contributes to reducing floods and damaging the population in times of rain and storms. After the studies carried out, a rainwater harvesting system was planned and executed through gutters installed on the roof. This water is directed to an equipment (filter) that first separates the water from the larger residues through a stainless steel filter, passes through a limestone to regulate the pH, then is chlorinated by a chlorine doser, disinfecting the same and finally passes through the filter of 150 micas, realizing the complete filtration of the remaining residues, leaving the water ready for consumption. The treated water is directed to the reservoir, which will pump it into the water tank of the residence. In order to prove the system's ability to treat water, water quality tests were performed and its efficiency in terms of water savings was based on the utility's water utility bills. The results showed that the system is efficient, proving the quality of the treated water, which was considered drinking water by the laboratory, besides generating a large drop in the consumption of water supplied by the concessionaire, which consequently generated a financial saving in the invoice values. In addition, the system is sustainable and environmentally friendly, and contributes to reducing floods and damaging the population in times of rain and storms. From the results found, it was concluded that this project for the capture, treatment and use of rainwater under study is a viable alternative.
