Water loss control programs are now indispensable for the management of water supply systems due to increasing drinking water demand. In this sense, this work shows the results of water losses study in a small area of coophema supply system located at the of Cuibá city, Mato Grosso state, central Brazil. The methods of water balance and minimal night flow were used to quantify the water loss volume. All the data used were provided by the Companhia de Saneamento da Capital (SANECAP) and measured in the field using electromagnetic flow meters and pressure datallogers. Before being used to calculate the water loss, the normality test were applayed to consumption, flow and pressure data to verify the adherence of the observed values with the theoretical distribution function. The calculated water loss by both methods is higher than the rate recorded in 2009 in the annual report of the Sistema Nacional de Informações de Saneamento (SNIS) for the Cuiabá city.
