Integrated Storm Water Management

Climate change has led to more frequent and intense storm and rainfall events along with increased flooding, storm water runoff, and soil erosion. These are forcing planners and storm water specialists to develop strategies dealing with greater volume and velocity of storm water. At the same time, urban areas are densifying and land is more covered with sealed surfaces.

As the Baltic Sea region is estimated to face more frequent and heavier rainfalls, the current planning and management practices have proven to be weak in meeting these challenges. Thus, the project idea is to create higher quality, cleaner and safer urban environment and increase urban sustainability.


iWater team in Söderhamn

iWater team met in Municipality of Söderhamn earliet this spring at the 3rd international meeting. Besides the training of the integrated storm water management (ISWM) and green area factor tool (GAF), the team had a chance to visit Granskär´s wetland and get to know the host city´s urban planning processes. The agenda included capacity building and green area factor (GAF) worskhops among others. More than 40 participants studied and learned how to implement integrated storm water plans in their cities.


iWater - Integrated Storm Water Management project (2015 – 2018) has been granted for the EU Strategy for the Baltic Sea Region´s HA Climate Flagship Status. The flagship status is a recognition for the iWater´s work for transnational cooperation within urban planning and integrated storm water management.
