About project

Water from surface reservoirs must in all cases be treated to obtain healthy water for human consumption, and often water is treated by flocculation and ozonation processes. Due to the impact of climate change affecting changes in surface water temperature, precipitation reduction and surface water runoff, which will occur in the future, water treatment plants for human consumption will have to adapt to negative changes in raw water quality. During the project, research will be conducted on the water of the surface accumulation Butoniga which is used as a source of water for human consumption. Lake Butoniga is the largest surface reservoir used as a source of water for human consumption in Croatia, which supplies water to the southern part of the Istrian peninsula. Given that there are several communities in Croatia that receive water from surface reservoirs, which is the case in many places in similar climatic zones in the world, the results of the research would be significant for water supply and human health in all these cases. The proposed research will collect and process the water quality measurements of Lake Butoniga so far with an extensive lake sampling and analysis campaign through this project to create a mathematical model that could predict future changes in lake water quality based on input values.
