• Abstract:

  The multiple uses that are made of the water present in the Piauitinga river basin are conflicting, mainly for domestic supply, since the quality and quantity of available raw water have deteriorated over the years, due to several factors. This research aimed to analyze the hydrometering of the Integrated System of Piauitinga and show the importance of micromeasurement in the fight against losses. The investigation was guided by a conceptual framework of reference that made it possible to identify the five most recurrent anomalies in micromeasurement, a considerable technical factor. For the development of the research, quantitative investigation techniques were used, making use of information collected in the field by the monthly collection system of the Sanitation Company - DESO, obtained through reports that allowed identifying the characteristics, and quantifying the anomalies previously defined as parameter, making it possible to create percentage indexes in relation to the general occurrences of each location. Considering the analyzes carried out in this study, it can be stated that rates were found regarding real connections, ranging from 0.20% in a best scenario to 6.69% in the worst scenario for cut connections, from 15.98% to 43.95% for suppressed connections, and from 80.80% to 52.88% for active connections. The results showed that direct action is needed in the replacement of water meters, not only with the aim of establishing and charging targets, but also in promoting a better operation of the existing water meter park. Seeking to guarantee its sustainability, in view of the universalization of services with efficient management of the supply system.
