Hydraulic modeling is the modern way to apply world water engineering experience in every day practice. Hydraulic model is an effective tool in order to perform analysis of water supply system, optimization of its operation, assessment of system efficiency potential, evaluation of water network development, fire flow capabilities, energy saving opportunities and water loss reduction and ect. Hydraulic model shall include all possible engineering elements and devices allocated in a real water supply system regardless to hydraulic modeling program selection. In order to create high quality hydraulic model it is necessary to carry out measurement in water supply system and perform model calibration. The article presents principles and examples of formation of district metered areas and examples of model calibration. The article also presents case study of Šiauliai water supply system model application for water loss evaluation and localization. Determined that hydraulic model of water supply system helps to significantly reduce search areas of physical water loss formation and improves efficiency of further detection of water loss formation points by saving time and resources.
