Abstract
The distribution of water losses due to leakage from the water network is studied
as the first step of the mathematical model calibration procedure. In order to
calculate the leakage from pipe an empirical formula which takes into account
the length of pipe and mean pressure, and also contains certain coefficients, is
used. This leakage is carried to the terminal nodes and distributed between the
nodes proportionally to the pressure in the nodes. For determination of leakage
the measured pressure in control nodes is used. For evaluation of pressure in
other nodes an iteration process is applied which determines the leakage and
pressures intermittently. Computational results for water distribution network of
