Preserving the environment and making fossilfuels viable for energy production, as well as power grid losses and low efficiency of thermal power plants, have drawn human attention to the use of alternative and renewable resourcesof energy such as hydroenergy.One of the most effective approaches to operational managementof the urbanwatersupply networks is to control thesurplus hydraulicpressure in somepartsof thesystem.Therefore,utilizing thepotential head along main gravitypipelines route to recoverenergy can be considered as a favourable strategy for optimum flowcontrol and management of thewaterpressure in the network.In this study,by applying hydraulic simulationof a given water supply network,the important hydraulicparameters suchas available netpressure head in various locationsof waterpipeline and water reservoirs inflow havebeen derived.Hence,by considering these essentialparameters and taking into account the topographicstatusof water transmission route and hydraulicgrade line elevation at each point,thepower output was calculated at nine selected hydropower sites.In addition,to Prioritizing theconstruction and operationof theproposed hydropower potentials and providing useful guidance to authorities,investors and executive managers,a multi-criteria decision-making analysis based on the analytic hierarchy process was conducted according to five key criteria including technical,economic,social, passivedefence and environmental aspects.Hence,a comprehensive multi-criteria model based on AHP and questionnaires has been developed to rank hydroenergy production in proposed sites in a water supply network.By analysing the expert questionnaires and weighting to each of thecriteria and sub-criteria(pairwise comparison)in theExpertChoicesoftware,it was found that thetechnical,economic,environmental,passivedefence and socialcriteria were ranked in first to fifth place,respectively.The results showed that microhydropower potential sites in R.1183,R.1453 and R.57reservoirs with installed capacityof3100,4107and1072KW respectively,were ranked in thefirst to third priorityof construction in thestudied watersupply network.
