Pressure has an important effect on the occurrence of failures/leaks in water distribution systems (WDSs) or the
change of leakage in existing leakages. For this reason, monitoring the pressure is important especially for
analyzing the changes in the day and night, determining the fluctuations and applying pressure management
(PM) to ensure normal operating conditions. In this study, the effect of pressure on water losses and minimum
night flow (MNF) was carried out according to the Fixed and Varied Area Discharge (FAVAD) approach, which
allows the amount of leakage to be calculated based on the change in pressure and field tests. The minimum
flow rate and potential leakage were determined under the network operating conditions before the pressure
control in a region. Then, considering the features of the region, pressure was reduced with the pressure control
system and MNFs and leaks were monitored. By reducing the pressure from 9.10 bar to 3.2 bar in the region, the
MNF rate was reduced from 6.95 l/s to 3.29 l/s. The daily water savings in the system inlet volume is 78.44 m3/
day and the annual saving is 28,624 m3/year. The results obtained are very important for practitioners in terms of
implementing PM in the field.
