A wastewater treatment plant in Port of Trelleborg

Port of Trelleborg takes water seriously. Since earlier, we have three sedimentation basins in the eastern part of the port that clean the stormwater, and right now construction is underway on a new treatment plant for wastewater in the Baltic Sea’s most sustainable port.

The Port of Trelleborg has received wastewater from the vessels for a long time. Since June 2021, a total ban on the discharge of waste water into the Baltic Sea has come into effect, and more ships are therefore leaving this in port. Today, this waste water is sent on to the municipal wastewater treatment plant, which takes care of it and cleans it. Responsibility is a key word for the port’s sustainability work, and Port of Trelleborg is therefore installing its own treatment plant in the port which will clean the waste water in accordance with the best possible technology. All wastewater in the new port will be connected to the treatment plant before it is pumped on to Trelleborg municipality’s treatment plant.

The wastewater treatment plant is designed for 400 cubic meters per day. That means 146,000 cubic meters per year, which is the equivalent of 58 Olympic swimming pools!

The construction of the treatment plant is in full swing and this week the walls went up to the treatment basin. The facility is located in the eastern part of the new port between the intermodal terminal and the port’s new office and service building Waterfront. During fall 2023, the treatment plant will be put into operation.

The wastewater treatment plant is one of the activities in Port of Trelleborg’s EU project ”Green FIT 2025” which is co-funded by the EU.

”The “Green FIT 2025” project includes works implemented during 2021-2024. The port builds two new large berths for next-generation Ro-Pax vessels and installs shore-side electricity connections. Also, it secures supply of clean energy for ships, port operations (and city hydrogen production) by installing two wind turbines. At the new berths, two wastewater reception facilities are deployed. A port waste water treatment plant is constructed to allow for management of ship waste in an environmentally friendly manner. The port rail connections are reconstructed in a new layout, to ensure a faster handling of intermodal trains.”
