Basic sanitation is one of the human rights that must be ensured, with increasing population and increasing trade and industry, water has been increasingly used, as if it were an abundant and infinite resource. The multiple uses of water present in the Piauitinga river basin are conflicting, mainly for domestic water supply, since the quality and quantity of available raw water has worsened over the years due to several factors. The country's sanitation companies are currently directing and improving their activities in relation to loss control in order to reduce operating expenses and the amount of raw water abstracted from the sources since the observed rates are high. The present research aimed at analyzing the hydrometration of the Integrated System of Piauitinga and show the importance of micromediation in the fight against losses. The research was guided by a conceptual frame of reference that made it possible to identify five more recurring anomalies in micromediation, a considerable technical factor. For each location, the categories of savings, quantities and characteristics of the existing links were identified. For the development of the research, quantitative research techniques were used, using information collected in the field by the monthly collection system of the Sanitation Company - DESO, obtained through reports that allowed to identify the characteristics, and to quantify the anomalies previously defined as parameter, making it possible to create percentage indexes in relation to the general occurrences of each locality. The documentary analysis of water loss control programs already implemented also helped to understand the importance of this operational stage. Considering the analyzes made in this study it can be affirmed that in the analyzed municipalities indexes were observed in relation to real connections, which vary from 0.20% in a better scenario to 6.69% in the worst case scenario for cut connections of 15,98% to 43,95% for suppressed linkages, and from 80,80% to 52,88% for active linkages. The results evidenced that it is necessary to act directly in the replacement of the hydrometers by direct actions in those that present the anomalies, not only with the purpose of establishing and collecting targets, but also in the promotion of a better operationalization of the existing hydrometer park. As a consequence of the substitution actions, it is possible to obtain adequate results in the short term, providing a greater efficiency and effectiveness of the management of the supply system, seeking to guarantee its sustainability, in view of the universalization of services.
