Global and local water-related challenges are becoming increasingly severe due to climate change, population growth, industrialization and urbanization. Flooding is the most disastrous type of local challenge and causes significant problems in human livelihood. A particularly difficult situation occurs when the amount of water to be treated exceeds the capacity of the unit. Then untreated water needs to be led directly to the environment.

Good water quality is a global issue. In Finland the quality of tap water is very high and even better than the quality of bottled water. Kemira wants to help provide access to such clean and safe water everywhere. Kemira has identified problems in the way different industries and waterworks utilize the raw water process measurement data: most processes are not adequately monitored and problems cannot be efficiently solved every time.

Wastewater treatment plants (WWTPs) in Europe, in industrialized countries and increasingly in developing countries are under a high pressure regarding treatment efficiency, operational costs and environmental impact (e.g. CO2-footprint). The developed method combines state-of-the-art methods for simplified simulation studies and for using simulation to evaluate control concepts regarding functional, economic and environmental criteria.

Rivers without Boundaries (RwB) International Coalition is developing relatively simple, but comprehensive express-assessment method that allows to compare basin-wide environmental impacts of various water infrastructure development scenarios. Methodology is based on semi-quantitative assessment of cumulative impacts of flow alteration, basin fragmentation and creation of anthropogenic water reservoir in place of natural river ecosystem. We analyze how these impacts from one or several dams affect known environmental values in a given river basin. All measures of impact we use were suggested in scientific literature and our innovation is in combining them in one effective and transparent assessment tool, that could be customized and adapted according to situation in a given basin under assessment. Assessment results also allow to compare how much impact is caused per unit of produced energy providing a rough measure of ecological efficiency.
