Abstract: Water balance calculation is a well-known and adapted method to analyze district-metered areas (DMAs) of drinking water distribution system. Other application of water balance results can be training dataset for consumption forecast, monitoring and managing water loss. The vast amount of application makes it a very powerful tool, which is in contrary sensitive to the accuracy of the calculation. Uncertainty of flow metering decreases as the length of the time step decreases, however the uncertainty of stored volume measurement in tanks increases. Investigation of the limitations of water balance calculation in regard of uncertainty is necessary to develop analytical solution for optimal calculation time step.
