Stormwater bioretention: design, function and maintenance

Stormwater bioretention is a core green infrastructure technique mainly targeting water quality treatment. Further, they can also contribute to peak flow retention and urban amenity. Bioretention consists of vegetated soil filter media with a temporal water detention storage. The water infiltrates and is filtered by bio/geochemical processes in the filter media.

The technique is still a new, innovative technology. Especially in Sweden, but also world-wide, experience regarding their functionality concerning several pollutants, treatment process understanding, and long-term function are lacking. Drizzle targets these challenges and bring together several aspects with varying focus. They cover investigation of treatment processes in filter material and vegetation, overall treatment performance of filters with different designs and long-term function and maintenance implications.
