YIT and Stockholm Vatten AB have signed an agreement on E2 tunnel works for the new wastewater tunnel in Stockholm, Sweden. The work will begin in January 2020. The value of the contract is approximately EUR 130 million. The project is booked in the order backlog of the second quarter in 2019.

The project is part of the development of Henriksdal wastewater treatment plant. YIT has been successfully working in Henriksdal since 2016 in different projects.
