Abstract: The objective of this paper is to compare the results obtained in the estimate of the design flow rates to the dimension water meters of water submetering systems in buildings by means not only from an open probabilistic model but also from the empirical method recommended by the Brazilian Standard. As the final results show considerable differences in the design flow rates estimated by both methods, it is extremely important to perform field survey in order to check the obtained values. The open probabilistic model enables the practitioner to adjust the variables related to the water use to better reflect the flow rates in the plumbing system according to the different conditions of use. Due to this advantage, its use appears to be more beneficial than the empirical method, mainly concerning submetering systems where the specification of the water meters takes into account the design flow rate.
