The plant serves a population equivalent of 119,553, classifying it as a large agglomeration under EU regulations. It is situated along the Ebro River, which flows through the city and is a key water resource for the region. As a large agglomeration in a sensitive area, the plant is expected to provide at least secondary treatment, and likely tertiary treatment to meet nutrient removal requirements under the EU Urban Waste Water Treatment Directive (91/271/EEC). The regulatory framework ensures compliance with stringent discharge standards to protect the Ebro River and downstream ecosystems. The treated effluent is discharged into the Ebro River, which flows eastward into the Mediterranean Sea via the Ebro Delta, a ecologically significant wetland area. The plant plays a crucial role in maintaining water quality in the Ebro basin, supporting aquatic life and downstream uses including agriculture and recreation.

The plant discharges into the Ebro River, which drains into the Mediterranean Sea through the Ebro Delta. The delta is a vital habitat for migratory birds and supports diverse aquatic species. The plant's operations help reduce nutrient loading and pollution, protecting the river's ecological health and the downstream coastal environment.
