A water park has been constructed for the treatment of the pumped groundwater and stormwater from Roslagsvägen. A sedimentation basin is being built by the Swedish Transport Administration in connection with the construction of the Northern Link. The stormwater is led via an overloaded sedimentation basin, which is also supplied with large amounts of leaking groundwater from the metro. The goal is to reduce the phosphorus supply by about 25%.

Project objectives
“The project aimed to reduce the addition of contaminated substances to Laduviken by creating a water park between the roads Fiskartorpsvägen and Baron Rålambs väg. The water park is made up of two parts. In one the surface water is led from the Norra Länken road link to a filter area for treatment, before being drained into an existing ditch. The second part comprises open surface water ditches for water leaching from the Stockholm Transport metro system.” (Ref. 1)
Implementation activities
“The water park consists of two parts, in which one of the waterways leads from the heavily transported Norra länken, via the Swedish National Road Administration's disposal magazine, to a drainage area in the water park for further purification, prior to diversion to existing dike. The second part consists of stormwater ditches that transport drainage water from SL's subway to existing outflows in Laduviken. Both of these measures mean that an existing treatment plant in the northern part of the area will get a significantly better function as it will take care of water from smaller areas that are not so busy.” (Ref. 3)

Details on the roles of the organisations involved in the project
“The project was run by the Stockholm Water’s design and Construction Unit (Stockholm Vatten projekterings- och byggenheten) until 2007 when it was sold out. Project management was then acquired through consulting services from Ramböll. The Swedish Road Administration (Vägverket), SL, Akademiska Hus and Djurgården Administration (Djurgårdsförvaltningen) have all collaborated in the project.” (Ref. 2)
