VILLA DE DON FADRIQUE LA Wastewater Treatment Plant, La Villa de Don Fadrique, Castilla-La Mancha

VILLA DE DON FADRIQUE LA is a municipal wastewater treatment plant located in La Villa de Don Fadrique, a town in the province of Toledo, within the autonomous community of Castilla-La Mancha, Spain. The plant serves a population of approximately 5,500 residents, classifying it as a small agglomeration under Spanish and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland freshwater discharges from agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with EU effluent quality standards. The treated effluent is discharged into local watercourses that ultimately drain into the Tagus River basin, a major Iberian river flowing westward into Portugal and the Atlantic Ocean. The plant plays a key role in protecting the region's water resources and supporting the ecological health of the Tagus watershed.

The plant discharges into the Tagus River basin, which flows through central Spain and Portugal before reaching the Atlantic Ocean near Lisbon. The Tagus River supports diverse aquatic life and is an important water source for agriculture and urban areas. Downstream ecosystems include riparian habitats and wetlands that rely on adequate water quality. The plant's secondary treatment helps reduce nutrient and organic pollution, mitigating eutrophication risks in the river and its estuary.
