More than thirty percent of drinking water loss in many water distribution systems (WDSs) in Iran has made a
major concern for Iranian water utilities. Pressure management is a well known and useful tool for reducing
leakage. This paper presents an optimized pressure management model through optimizing PRV locations. The
PRVs location and their setting are formulated here as a multi-objective optimization problem. The objectives
are to minimize the total invisible leakage through pipes of the network and to minimize the number of installed
PRVs. A multi-objective genetic algorithm is used as the optimization model coupled with EPANET software as
the hydraulic simulation model. The model is applied to a real WDS in Iran with a high percentage of water loss.
Three management scenarios are analyzed with respect to the existing and new PRVs. The results show that the
proposed leakage control management is able to considerably reduce the high pressure values and mitigate the
relevant leakage in the network (e.g. 61% of leakage reduction relative to the initial leakage). The results show
that the asset will be conserved significantly by using a relatively low capital investment of system renovations,
compared to the total value of drinking water which is annually lost. Furthermore, the analysis of the scenarios
shows that the optimal setting of the existing PRVs can even decrease the leakage through the network without
any capital investments.
