Stormwater Management


DRIZZLE is a competence centre committed to excellent needs-driven research, and to develop pioneering stormwater solutions that minimize pollution loads on receiving waters; that minimize the risk for urban flooding; and that capture the opportunities that stormwater runoff can offer. So far, stormwater management has been mostly seen as a quantity problem, i.e. focus has been on transporting water from urban areas as fast as possible to avoid flooding. However, today’s stormwater management also needs to consider stormwater content and pollution. Moreover, stormwater has to be considered as an opportunity. DRIZZLE – Centre for Stormwater Management was formed with these guiding principles as a basis.

The needs-driven research within DRIZZLE consist of both laboratory studies and field studies, mainly in Luleå and Stockholm. In Stockholm, the Riddarfjärden catchment is the starting point for most of the studies.

DRIZZLE’s research activities are conducted in joint collaboration with its partners. The partners represent the whole value chain – from end-users, researchers, manufacturers of stormwater management solutions, sewers, consultancies, to operations and maintenance. Besides, City of Stockholm, Luleå Municipality, NCC and Tyréns are financing a PhD student each.

The active research collaboration that takes place in DRIZZLE between its stakeholders offer several advantages – the development needs of companies and municipalities influence the research activities, and the research collaboration gives the companies access to front-line knowledge that they use in the development of their goods and services.

The total funding for DRIZZLE is around 12 million Euro for five years. Vinnova accounts for around 4 million Euro and the participating municipalities, companies and Luleå University of Technology account for the rest.

DRIZZLE consists of 11 partners, i.e. Aarsleff Pipe Technologies, City of Stockholm, Järven Ecotech, Luleå Municipality, Luleå University of Technology (centre leader), NCC Infrastructure, Rent Dagvatten, Stockholm Vatten och Avfall, StormTac, Stormwater&Sewers, and Tyréns. New partners may join the consortia, provided that the potential partner fulfils the established requirements.
