The project's purpose was to build the industrial chimney and the intake and discharge pipes for the cooling circuit.
The cylindrical chimney with a reinforced concrete shaft was built in two distinct phases. The first phase was up to 149 metres high, with a platform for employees to rest and for locking the formwork. The second phase was carried out up to the final height of 225 metres.
The intake and discharge pipes, approximately 1,800 m long, were made up of 2.15 metre diameter steel core reinforced concrete pipes, with a 0.11 metre thick outer and inner concrete layer.
