BATEA Wastewater Treatment Plant, Batea, Catalonia, Spain

BATEA is a wastewater treatment facility located in Batea, a municipality in the comarca of Terra Alta, Tarragona, Catalonia, Spain. The plant serves a population of 2,311, classifying it as a small agglomeration under EU classification. It is situated inland, away from coastal areas, and operates within the Mediterranean climate zone. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant's designed capacity is 3,700 cubic meters per day, and it currently discharges an average of 341.34 cubic meters per day, indicating significant spare capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Ebro River basin, one of Spain's major river systems. The Ebro River flows into the Mediterranean Sea via the Ebro Delta, a ecologically sensitive area that supports diverse aquatic life and important migratory bird populations. The plant's advanced treatment helps reduce nutrient loading to this downstream environment.

The plant discharges into the Ebro River basin, which flows through Catalonia to the Mediterranean Sea. The Ebro Delta is a ecologically significant area supporting diverse aquatic life and serving as a key migratory corridor for birds. Advanced treatment at BATEA reduces nitrogen and phosphorus loads, helping to protect downstream water quality and prevent eutrophication in the delta and coastal waters.
