Käppalaförbundet
The Käppala Association treats wastewater from over 500 000 inhabitants in eleven municipalities located north and east of Stockholm. Our treatment plant, the Käppala wastewater treatment plant, is Sweden’s third-largest, and employs a very effective treatment process.
Before the Käppala plant started operating, huge amounts of raw sewage were discharged into local watercourses, lakes and the Stockholm archipelago. This caused problems involving disease transmission and environmental pollution.
