Sažetak
The average water pressure in a water supply system is usually determined as the weighted (by some parameter) average value of all pressures. In IWA (International Water Association) methodology, average pressure is used for calculating 'Unavoidable Annual Real Losses' (UARL), which are a core component for deriving the ILI index (Infrastructure Leakage Index). This paper gives an overview and the comparison of several approaches for determining the average pressure required for the calculation of UARL. The determination of the average water pressure is based on field pressure measurements and the use of calibrated hydraulic mathematical model. Some advantages and disadvantages of each method is pointed out.
