ORGAZ Wastewater Treatment Plant, Orgaz, Castilla-La Mancha, Spain

ORGAZ is a wastewater treatment plant located in Orgaz, a municipality in the province of Toledo, Castilla-La Mancha, Spain. The plant serves a population of approximately 6,660 people, placing it in the small agglomeration category under EU regulations. It is situated along the CM-410 road, reflecting its role in the region's rural wastewater infrastructure. The plant provides 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. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local watercourse that ultimately drains into the Tagus River basin, one of the Iberian Peninsula's major river systems. The Tagus flows westward through central Spain and Portugal, emptying into the Atlantic Ocean near Lisbon. The plant's operations help protect the local watershed and downstream aquatic ecosystems from untreated pollution.

The plant discharges into a tributary of the Tagus River, which flows through central Spain and Portugal to the Atlantic Ocean. The Tagus basin supports diverse aquatic life and is an important migratory corridor for fish species. The region's Mediterranean climate with seasonal rainfall means the receiving water body may experience variable flow, making consistent treatment quality important for ecological health.
