The SPN-Group activities related to stormwater runoff from urban areas (separate sewered areas), highways and roads focus on pollutant characteristics and corresponding process engineering related to treatment and mitigation methods for the runoff.

Methods for the “design” of natural occurring processes in pond and infiltration systems for mitigation and treatment of the runoff have thereby been emphasized. In this respect both laboratory and field experiments have been devoted to investigate physico-chemical and biological processes that are important for the design.

The research has resulted in design principles for both wet detention ponds and infiltration ponds. In this respect, the development has focused on a triple purpose:

	Systems that result in an effective treatment of a wide range of pollutants found in the runoff
	Recreational aspects that observe the concept of “water in the city”
	Sustainable and low cost stormwater management by applying nature’s own processes

The recent research activities concentrate on wet detention ponds for combined pollutant removal and recreational purposes based on a conceptual understanding of the governing physico-chemical and biological processes. Focus is at present on the oxygen balance of wet detention ponds including development of a method for determination of the air-water mass transfer. The ultimate goal is to apply this knowledge via developing a conceptual process model for design and management of wet detention ponds.
