Environmental context
The plant's discharge enters the Gállego River, which flows into the Ebro River, one of the largest rivers in Spain. The Ebro River basin supports a variety of ecosystems, including riparian forests and wetlands, and is home to species such as the European eel and the Iberian barbel. The region's semi-arid climate makes water quality management critical for both ecological health and human uses like irrigation.
