Facilities for treatment of stormwater runoff from highways

Abstract

Stormwater is the major water inflow to many water bodies in Stockholm. Stockholm City has adopted a strategy, which defines the need to treat different kinds of stormwater entering different receiving waters. The Stockholm Water Company has tested various ways of treating stormwater. In 2000, the City of Stockholm arranged a stormwater treatment technology competition. Prizes were awarded to four winning entries. One installation was completed in 2001 and another is now under construction.
