Reducing losses in the water supply system is a key issue in the world's basic sanitation. Losses of up to 50% cause concern both for the reduction of potable water reserves and for the increase in the cost of distributed water. Many systems are objects of study to increase their production capacity when, in fact, it would suffice to reduce losses. This study aims to classify the level of performance in the management of the supply system in the city of Vitoria through the indicators of real losses between the years 2014-2017; analyze the information and estimate the lost volume of water in visible leaks obtained in the application of the Failure Form by the Concessionaire in 2016 and present the study applied on the deactivation of the treated water elevation in the Joana D'Arc sector that guaranteed the continuous supply. The bibliographic review shows the concepts, methods of estimating performance indicators, management strategies and operational control, actions to reduce real water loss in the water supply system, and the panorama of the loss index at the national, state and municipal levels. Each objective of this dissertation had a methodology applied; however, all are based on a case study through the data provided by the CESAN Concessionaire. The results and discussions allow us to conclude that the systematic and continuous monitoring of the actions, the use of loss estimation methods to aid management and control in the supply system, tends to reduce the volume lost in leaks, but not zero, and guaranteeing sustainable supply to society.
