TAUSTE Wastewater Treatment Plant, Tauste, Aragón, Spain

TAUSTE is a wastewater treatment plant located in Tauste, a municipality in the Cinco Villas comarca of Zaragoza province, Aragón, Spain. The plant serves a population equivalent of 13,736, placing it in the medium agglomeration category under EU classification. As a Spanish facility, TAUSTE operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations between 10,000 and 150,000 population equivalent, the directive requires secondary treatment as a minimum, with more stringent treatment in sensitive areas. Spain has designated many of its river basins as sensitive, particularly those discharging into the Mediterranean. The plant's treated effluent is discharged into the local hydrological network, which ultimately drains into the Ebro River basin. The Ebro is one of Spain's major rivers, flowing eastward to the Mediterranean Sea. The receiving water bodies support diverse aquatic life and are important for irrigation and regional ecology.

TAUSTE is located in the Ebro River basin, one of Spain's largest and most important watersheds. The Ebro River flows approximately 930 km to the Mediterranean Sea, forming a large delta that is ecologically significant for migratory birds and aquatic species. The plant's discharge contributes to the water quality of local tributaries that feed into the Ebro, affecting downstream ecosystems including the Ebro Delta, a vital wetland area.
