The water losses management provides cost reduction for sanitation companies and, thus, for the treated and distributed water’s final users. In the face of the recent episodes of hydric crisis in the state of São Paulo, it is essential to have a good water supply management system, which includes controlling the water loss volume in the system. The easiest way to manage this control is based on the water balance, in other words, calculating the difference between the distributed volume and the volume measured in the consumption units. This work presents one case study at the municipality of Altônia, in Paraná, where the continuous expansion of the water supply system has led to the increase of the water loss volume on the distribution process. The municipality has chosen procedures as the appropriate and periodic maintenance of the network, installation of new water meters and pressure reduction valves and the monitoring of leakages with mechanical tools. Thus, it was possible to reduce the water loss volume by half.
