Abstract Issues related to the Sava River development and its harnessing in the City of Zagreb territory are briefly presented. In the long run, this scheme will enable the potable water demand of the City of Zagreb and its greater area to be met, and the demand for food and energy to be partly met. The scheme will also open new town planning options in the neighbourhood of the project site, enable preservation of natural assets and creation of new sport and recreational amenities. Further, the new system is planned to enhance flood control in the river valley, stabilize the riverbed, improve the quality of the Sava water (stagnant and groundwater), and improve the safety of the existing systems (power generation, water supply, drainage, sewage, etc.). Alternative approaches to finding an optimum solution while respecting the economic, environmental, social, developmental and urban values, are presented. The solution selected is described and the conditions necessary for its implementation are presented.
