Wastewater project update: Better treatment by 2031

The project for Stockholm's future wastewater treatment (SFA) has an update for February 2026. Work on rebuilding Henriksdals treatment plant and a new tunnel from Bromma is proceeding as planned, with wastewater from Bromma expected to be diverted to Henriksdals in 2028 and the entire plant completed by 2031. The budget is 19.5 billion SEK (at March 2023 price levels), and the project is following its revised time and cost plan, despite ongoing risks concerning the facility's condition, market conditions, and material availability.
