The performance of the sanitation sector is essentialto collaborate with the advances that are necessary to guarantee the sustainable management of drinking water and its availability for all, especially in relation to water losses, as high rates have been recorded by several concessionaires. The objective is to reduce losses to the point called the Economic Level of Losses (ELL), in which there is a balance between the cost of the effort to combat losses and the savings obtained by this effort, which promotes a reduction in production costs of water and increased revenue. Thus, this research seeks to answer the following question: How can the ELL be estimated in Brazilian sanitation companies, to provide the financial break-even point in loss management? From a case study, using loss quantification techniques and calculations to estimatethe ELL in a large Brazilian concessionaire, a systematic was elaborated that can be used as a reference by other companies in the sector. The systematic was conceived and applied in the context of a CAESB DMA (DMC.PLT.001), with the support of an Excel spreadsheet for calculations, which estimated the optimal ELL of 27.3% (171.68 L/conn.day) for real losses, and 8.9% (39.98 L/conn.day) for apparentlosses due to sub-measurement. The ELL of apparent losses due to fraud was financially viable only when considering the estimated recoveries of revenues from fraudulent consumption, the effective interruption of fraud and the receipt of applied fines.
