NIB and the City of Stockholm have signed a second ten-year loan agreement to double the capacity of Stockholm’s main wastewater treatment facility.

The SEK 1,500 million (EUR 158 million) loan will partly finance the expansion of the Henriksdal underground wastewater treatment plant and the construction of a 15-kilometre sewer tunnel under the southern-central part of Stockholm, Sweden.

The project will double the capacity at Henriksdal to more than 500,000 cubic metres per day. As a result, Henriksdal is expected to become the world’s largest underground wastewater treatment facility as well as the largest membrane bioreactor technology facility.

This is the second loan agreement to be established between NIB and the City of Stockholm for the same project. The first, a SEK 3 billion loan agreement, was approved in 2016. The second loan agreement has been established due to an increase in the investment size and project scope. This includes expanding the Sickla plant, located adjacent to Henriksdal, to cope with the higher loads that may occur as a result of climate change.

Stockholm is the capital of Sweden and the most populous city in the Nordic–Baltic region, with 935,619 residents at year-end 2016. The city is one of the fastest-growing regions in Europe and benefits from a strong economy and a rapidly growing population.

NIB is an international financial institution owned by eight member countries: Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, Norway and Sweden. The Bank finances private and public projects in and outside the member countries. NIB has the highest possible credit rating, AAA/Aaa, with the leading rating agencies Standard & Poor’s and Moody’s.
