As a result of the new production lines in the factory, it has been necessary to project a retrofitting of the treatment plant built by CORPI in 2016.

The expansion includes a pumping well for the new production line, a screw conveyor to increase the dryness of the screening reject and an aeration tank that will double the current capacity to improve the performance in removing organic matter.

The expansion works have been completed during the month of March 2022 and the quality of the treated water fully complies with the regulations for discharge into the sewage system.
