NIB has signed a 10-year loan agreement with the City of Stockholm to build the world’s largest underground wastewater treatment facility at Henriksdal.
The aim is to accommodate a growing population, reduce overflow into Lake Mälaren, and improve the quality of water discharged into the Baltic Sea.
The SEK 2 billion (EUR 172 million) loan will be used to double the treatment capacity of the Henriksdal plant to serve 1.6 million people.
The expansion involves closing the Bromma facility and rerouting wastewater through a new 14-kilometer underground tunnel to Henriksdal, which will become the world’s largest membrane bioreactor technology facility.
This technology will notably reduce phosphorous and nitrogen discharges into the Baltic Sea and decrease overflows of untreated wastewater into Lake Mälaren. The total project cost is estimated at SEK 22.5 billion, and completion is expected in 2031.
NIB has previously approved loans for the project in 2016 and 2017, with the total outstanding loans amounting to SEK 4.5 billion.
The City of Stockholm appreciates the opportunity for debt financing by NIB, which complements the bond market financing of the investments.
NIB, an international financial institution owned by eight member countries, is pleased to continue supporting Stockholm’s Future Wastewater Treatment project, which aligns with its mandate to enhance productivity and benefit the environment of the Nordic-Baltic region.
