Integrated stormwater management in cold climates

Integrated stormwater management is based on the natural processes in the water cycle and the criteria for sustainable development. The aim of this paper was to investigate which integrated stormwater system components might be suitable in cold climate regions. The evaluation was based on literature reviews and studies made in Lulea, Northern Sweden. It was found that porous pavement, grassed waterways (swales, ditches), wet pond, and percolation basin were the most suitable integrated stormwater system components in cold regions whereas dry basin, stormwater infiltration surfaces, and stormwater reuse seemed to be the less suitable. Polluted snow may be treated at a central (large-scale) snow deposit; cleaner snow may be placed in many local snow depots.
