RECAS Wastewater Treatment Plant, Recas, Castilla-La Mancha, Spain

RECAS is a municipal wastewater treatment plant located in Recas, a town in the province of Toledo, Castilla-La Mancha, Spain. The plant serves a population of around 3,249, classifying it as a small agglomeration under Spanish and EU regulations. It is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. The plant provides secondary treatment, which is the standard level required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's discharge volume is 639.30 cubic meters per day, indicating consistent operation. The treated effluent from RECAS is discharged into local watercourses that ultimately 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, emptying into the Atlantic Ocean near Lisbon. The plant's operations help protect the ecological health of these downstream waters by reducing pollutant loads.

RECAS discharges into the Tagus River basin, which flows through central Spain and Portugal before reaching the Atlantic Ocean. The Tagus supports diverse aquatic life and provides water for agriculture, industry, and drinking water for millions of people. The plant's secondary treatment helps mitigate nutrient and organic pollution, contributing to the ecological balance of this transboundary river system.
