Better wastewater treatment plant for Stockholm residents

Stockholm Vatten AB plans to invest up to SEK 225 million to modernize and improve the treatment process at Henriksdal Wastewater Treatment Plant. The funds will be used to replace old machinery in the aeration basins (bioline 2-5) to ensure the plant can handle future wastewater treatment needs, especially with the connection of wastewater from Bromma Wastewater Treatment Plant. The work will be carried out in stages between 2026 and 2031.
