Storm Water Planning and Modelling

The importance of run-off and flood water management has increased in the urbanising environment. More attention is paid to run-off water management in large, paved areas (urban environment, industrial areas, yards) in particular. In addition to management of run-off waters, their treatment is also a topical issue.

Sweco is the leading run-off water expert in the Nordic countries. Our solutions and experts are actively participating in the planning of cities and residential areas, from the zoning phase to construction and all the way to network renovations.

Our experts calculate and dimension the run-offs as well as the sizes of channels and pipes and plan the devices and systems needed for water delay in the network. We utilise the field’s best modelling and dimensioning software. In addition to hydraulic experts, we have the landscape and environmental experts of run-off water management as well as the professionals of infrastructure and geotechnology.
