With climate change, many cities face a challenge of managing increasing amounts of rainwater. Overloaded sewer systems cause flooding, which is harmful to both the city as well as its citizens. But new innovative solutions deal with stormwater while creating a green breathing space in the city for the people to enjoy.

Smart rainwater management solves more problems in the cities

In the coming years, many larger cities have to come up with solutions for the challenges of increasing amounts of rainwater and more extreme weather. By implementing solutions that help protect densely populated and developed areas against flooding, the development of the square serves as an example to be followed when the rest of the city is to be climate-proofed. By actively making use of a city’s green areas in the fight against pollution and securing the city against cloudbursts, smart ways of handling rainwater solve a great deal of the problems, cities today are facing.

New architectural landmark

With a distinctive design, Värtaterminalen – the terminal for the Sweden-Finland-Baltics ferry connections – is a landmark of Stockholm and offers a  coherent and smooth transition from Stockholm city to the harbour area. With architectural and environmental innovation, the award-winning terminal solves problems with increasing amounts of rainwater, while offering a green rooftop park for relaxation and social interaction to the people of Stockholm. This way, the design of Värtaterminalen makes Stockholm a bitter city to live in for still more people.

Minimising risk of floods

With urbanisation, cities today mainly consist of hard surfaces such as paved streets, roofs, and squares. This makes it still more difficult for rainwater to absorbed naturally, why sewage systems are the main channel for surplus surface water. In recent years, they have been under severe pressure due to increasing amounts of rain and generally more extreme weather. Therefore, governments and municipalities are trying to ease the strain on the infrastructure systems and minimise the risk of flooding. A great way to do so is more greenery in the cities. Plants can absorb large quantities of water and transform CO2 into clean air, improving the air quality and the general quality of life for the people who live there.

Excess rainwater solves the problem

Värtaterminalen is a part of Stockholm's strategy in easing the pressure on the sewers. Therefore, it has an urban park on the roof, reducing hard surfaces and providing rainwater with a natural way of being absorbed. The park also makes the roof a natural meeting point and relaxation area for people, offering a great view of the city. The park features flowerbeds and smaller bushes in combination with channels that lead the rainwater to the plants. Using the rain as watering for the plants, drastically reduces the amount of water that is directed to the drainage system.

Contrast Freestyle™ and Exact channel

In Värtaterminalen the innovative combination of Contrast Freestyle and Exact drainage channels is a great way to use rainwater as a resource, while also adapting the climate changes.  Contrast Freestyle is a highly customisable edging system. In the case of Värtaterminalen, landscape architects chose a galvanised edging, fitting perfectly with the colour scheme selected for the project. In this case, it is used as the defining edge between the hard surfaces and the flower bed. The Exact channel with an integrated sediment trap runs along the edge and through perforated sides allowing the surface water to run into the flower bed.
