STORM OVERFLOWS IN NORWAY- POLICIES AND PRESENT SITUATION
Storm overflows contribute considerably to pollution. However, the pollution authorities and municipalities often fail to take appropriate measures to correct the situation. Investigations in Norway have shown that the storm overflow constructions and maintenance usually are not satisfactory. On the other hand, research projects have shown that storm overflow types, like the swirl concentrator, perform very well.
These facts are beginning to be appreciated because research projects and activities to work out guidelines concerning storm overflows have now increased.
