A cover was built in Juankoski over the sewage treatment plant basin, to protect it from rain, and particularly in winter, from freezing. In extreme frost, heater blowers can be placed underneath the cover to keep the frost away.
We manufactured a steel frame over the service bridge to make it possible to walk on the bridge after the cover has been installed. 3D design was used in the planning of the cover to make straight and round surfaces meet each other.
Additionally, an air vent was made on the other end to ensure ventilation when carrying out service tasks.
