Facilities for Treatment of Stormwater in Stockholm

Stormwater is the major water inflow to many of the 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. It also arranged a stormwater treatment technology competition. Prizes were awarded for four of the entries. One installation was completed in 2001 and another will be built in 2002.
