ANOVER DE TAJO Wastewater Treatment Plant, Añover de Tajo, Castilla-La Mancha

ANOVER DE TAJO is a wastewater treatment plant located in Añover de Tajo, Toledo, within the autonomous community of Castilla-La Mancha, Spain. The facility serves a population of approximately 5,175 residents, classifying it as a small agglomeration under Spanish and EU regulations. The plant operates with secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The treatment process involves biological degradation of organic matter, reducing biochemical oxygen demand and suspended solids before discharge. The treated effluent is discharged into the local watershed, which ultimately drains into the Tagus River basin. The Tagus River is the longest river in the Iberian Peninsula, flowing westward through Spain and Portugal to the Atlantic Ocean near Lisbon. The plant's operations contribute to protecting the ecological health of the Tagus basin and downstream water bodies.

The plant discharges into the Tagus River basin, which flows through central Spain and Portugal before reaching the Atlantic Ocean. The Tagus River supports diverse aquatic life and provides water for agriculture and urban use. The secondary treatment helps reduce nutrient and organic pollution, safeguarding the river's ecological balance and downstream ecosystems.
