RESUMO

Water consumption under measurement can represents about 8 to 23% of the produced water in Brazil. It can be caused by oversized meters or others external cause. Low flows are common in cold water systems with a reservoir controlled by conventional ball cock faucets. This work presents a study case developed in 22 low-income houses located in Campinas, Sao Paulo that aims to determine the water consumption under measured, to identify its causes and to formulate actions to reduce this problem. Its also contemplates a laboratory investigation to analyze the performance of conventional and ultra high flow ball cock faucets in the same situation of supplying. The results of the study can indicate some methods reduce the under measurement of water like the use of water meters with different range of accuracy combined with two types of ball cock faucets. Besides that, it could be checked the water volume lost by the actual model used, flow behavior of the population studied, a consumption index , the evaluation of the water meters installed in that region considering the measurement accuracy
