Abstract: The issue of Water Loss in Supply Systems has become increasingly relevant in recent decades, mainly due to the increased frequency of water scarcity events. Another preponderant factor for the increased attention on this topic is from the economic and financial point of view, with issues related to the high costs of electricity used in the production and distribution of treated water and the waste of natural, operational and revenue resources. In this way, consistent, continuous and effective structuring actions and Action Plans for the evaluation, control and reduction of losses are essential to achieve expressive results in the reduction of water losses. For this purpose, the International Water Association (IWA) recommends the use of the water balance methodology for the diagnosis of losses in the water distribution system. By this methodology, losses are divided into apparent and real. This distinction is important, as the tools for managing and combating each of the typologies differ substantially. In this context, the present work presents the improvement in the performance of water loss management with the effective achievement of results in the reduction of losses in the region covered by the East Business Unit, operated by the Sanitation Company of Minas Gerais, from the use of the techniques and methodologies proposed by renowned institutions that deal with the issue of Water Loss in Distribution, associated with the application of innovative technologies with a cost/benefit compatible with the economic condition of the System. The results achieved confirm that it is possible to control and decrease the loss rate based on the development of integrated actions at the strategic and operational levels of governance, based on the tools proposed by the IWA and respecting local realities.
