The largest rain gardens in Sweden (thus far) has been created in Göteborg (Kviberg park). Kviberg's multisport arena was completed in the summer of 2015 in the northeastern part of Göteborg. Around the facility, there are parking spaces with a capacity for 500 cars. In order to handle the rainwater flowing from the parking area, approximately five per cent of the total area has been used for rain gardens, which both clean and store the rainwater. (Ref. 1, 2)

The project aimed to make the banks of the river Sava a more secure place by setting up illumination poles and thus motivate people to go there also by installing potable water fountains. The project includes environmental friendly illumination of both sides of the river Sava, development of 6 water pipes and toilets and renovation of the pedestrian and bike paths (4 sq km). The project in the second phase will also include additional illumination and water stations up to Jankomirski Bridge (in total 16 km, on both sides of the river Sava) (Ref 1).
The locals use the area for running, dog walking and for relaxation. Previously the place didn't have lights which made it unsafe during the night. The Mayor promised the citizens to return the river as well as an emphasis on the bridges that "conect, rather than separate" (Ref 1, 2, 3, 4).

The project is focused on cultivating bazaars for climate-safe and labour-intensive cultivation and is located in an underground space under a shopping and community centre in Högdalen, a southern suburb of Stockholm. This underground cargo space at the shopping centre has been converted to a high-technology farming space that can be active all year-round. The goal is to create a small-scale industry and provide local job opportunities (Ref. 5, 6, 7).
