Water pollution in Odra River due to 1) malfunctioning and insufficient capacity waste-water treatment plant in the city of Velika Gorica 2) other sources of pollution (illegal outlets into Odra) 3) agriculture especially expressed in the Upper reach, but also present downstream in the Middle and Lower reach - Development of toxic cyanobacteria due to increased level of phosphates and nitrates from waste water treatment plant and agriculture - Development of nitrophilous and toxin resistant plants - Considerable changes in aquatic community composition and structure Revitalization measures of removing contaminants from water streams of developing constructedl wetland (CW). This solution is predicted for: Urban Waste Water (small settlements, individual homes, tourist and organic farms, tourist facilities, • non-point source pollution (urban, agricultural and roadway runoff); Method is based on extensive research of the application of various plant species, sand substrates and water flow modes, enabling efficient removal of pollutants from water through physical and chemical processes, microbial activity and plant uptake Deposition of fine organic particles in the riverbed Hydrological (river impoundment) and organic pollution (waste-water treatment plant) upper reach - Anoxia appearance, development of anaerobic bacteria in sludge;- toxic metal accumulation in the riverbad;- Considerable changes in aquatic communities due to changes in substrate composition Silt / sludge removal measure a consequence of the discharge of untreated water from treatment plants in Velika Gorica River fragmentation due to malfunctioning siphon hydrological, uncompleted siphon point between Upper and Middle reach - Population fragmentation and alteration of migration patterns of aquatic species (fish, aquatic macroinvertebrates, aquatic mammals, etc.) - Lower genetic diversity in local populations and appearance of genetic drift Revitalization measures reconnection of the Upper and Middle reach of the river Oder, which would flow upstream part of the River Odra has increased significantly. Solution reconnection riverbed implies microtunelling below flood control channel Sava - Odra of ameliorative channel GA2 by the middle reach of the Odra.
