Identificação e mitigação de perdas de água em rede de distribuição através do monitoramento e controle de pressões

Abstract

The topic of this study is the Identification and Mitigation of Water Losses in a Distribution network through the Monitoring and Control of Pressures. In order to complete the study, some initial theoretical fundamentals characterizing the water as a strategic resource were presented. Also, the losses and wastes, as well as the physical and non-physical losses of water in the Distribution System, the evaluation of these losses, their origins, classification and their possible causes of occurrence were showed. Losses indicators in the Water Supplying System have also been studied for a better understanding of the target subject. Therefore, the methodology developed to characterize the System is used. The mapping of the pressures, the definition of the supplying sectors, the definition of the critical points related to the pressure at these points, is performedaiming a later substitution of these points or the implementation of reduction pressure valves at them. The calculation of the reservation in order to implement the Pressure Control and Reduction System is also performed. After the dimensioning of the System is done and the evaluation of the micromeasurement is performed it is possible to detected the water losses. The case study methodology applied was developed in the city of Pouso Alegre MG, making use of the data collected by COPASA-MG. The needed rates and values to conclude this study are also calculated, with the implementation of pressure reduction valves in a subsector of the municipality, subsector VRP YARA. After all the necessary steps to finalize the study have been applied, the obtained results and conclusions reached are listed.
