TORRIJOS Wastewater Treatment Plant, Barcience, Toledo, Castilla-La Mancha, Spain

The TORRIJOS wastewater treatment plant is located in Barcience, a municipality in the province of Toledo, within the autonomous community of Castilla-La Mancha, Spain. The plant serves a population of approximately 27,560 people, classifying it as a medium-sized agglomeration under European Union regulations. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures compliance with European standards for wastewater treatment. The treated effluent from the plant is discharged into local water bodies that eventually drain into the Tagus River basin, one of the most important river systems in the Iberian Peninsula. The Tagus River flows westward through Spain and Portugal, ultimately reaching the Atlantic Ocean near Lisbon. The plant plays a key role in protecting the water quality of this transboundary river system and the downstream ecosystems it supports.

The TORRIJOS plant discharges into the Tagus River basin, which flows through central Spain and Portugal before emptying into the Atlantic Ocean. The Tagus River supports diverse aquatic life and provides water for agriculture, industry, and drinking water for millions of people. The plant's treatment helps reduce nutrient and pollutant loads, protecting the river's ecological health and the sensitive estuarine environment at its mouth.
