PUEBLANUEVA Wastewater Treatment Plant, La Pueblanueva, Castilla-La Mancha

PUEBLANUEVA is a wastewater treatment plant located in La Pueblanueva, Toledo, within the autonomous community of Castilla-La Mancha, Spain. The facility serves a population of approximately 5,397 residents, classifying it as a small to medium agglomeration under Spanish and EU regulations. The plant operates with secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. 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 help protect downstream water quality and aquatic ecosystems.

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. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain the ecological health of the river and its downstream estuary.
