One of the big challenges for the sanitation companies is fighting against the water waste in the supply system, seeing that, the water demand is bigger and bigger due the big populational increasing and the hydric resources even more scarce. In Brazil, the water waste rates in the supply system are close to 40%, so, almost half of the water produced is lost through the physical losts those referring to the leaks in the distribution networks or through the apparent lists, that are losts errors in the measurement, frauds (clandestine connection) and register fails. The control and the reduction of the water losts besides reduce the use of hydric resources bring financial and operational benefits for the sanitation companies. In this context, this study has the objective to evaluate the potencial loses and propose strategies to improve the operational control of "SAA". The lose control have been started in the county Águas Mornas with the installation of macro meters in the county borders, having control of the water volume imported and exported to Santo Amaro da Imperatriz. Right after this, has been performed a sectorization with the creation of four "distritos de medição e controle" (DMC), installing right after macro meters in each border of DMCs. With the creation of those DMCs, has been possible evaluate the labels for each sector. Through this, minimum night flows had been detected, the real rates lost for all the county being this value in the hydric audit to have the aparental lose rates. During the research, CASAN had install a supervisinory system, that through of the telemetry is possible remotely monitor the flows of the treated water in the tank output and two more points of pressure in the county. After the application of those methods it was noticed a increasing in the operational control and in the lose rates of the Águas Mornas SAA, before the rates were 53,91% and now it is 31,9%.
