Welcome to Infra Stories.
Stories about places all across Nordics, where infrastructure projects with significant impact for the local communities have been built. Stories about innovative and sustainable solutions.
Today we travel to the city of Norrköping, Sweden. Where the municipality is trying to filter contaminated stormwater before it gets to the Baltic Sea.
Located at the mouth of the Motala River in Bråviken Bay, Norrköping is Known as the Manchester of Sweden. It’s an industrial city, a port on an inlet of the Baltic Sea, where former brick warehouses and mills perch dramatically on the edge of the city docks. It boasts a wealth of cultural and outdoor activities and interestingly has more ancient rock carvings than any city worldwide.
But its beautiful location also brings some issues. As a municipality so close to the sea, it inevitably faces challenges when trying to reduce the number of pollutants released into its waters. Pollutants further inland in streams and rivers have time to be naturally filtered through ditches, gravel and sand. Unfortunately, in the case of Norrköping, we’re talking about a location right next to the Baltic Sea, one of the most sensitive and polluted seas in the world, and one which is particularly affected by eutrophication.
An innovative solution. Giant Uponor Vaults stops untreated stormwater and give the Baltic Sea some breathing space.
