Aldea en Cabo Wastewater Treatment Plant - Toledo, Castilla-La Mancha, Spain

The Aldea en Cabo wastewater treatment plant is located in the municipality of Aldea en Cabo, in the province of Toledo, within the autonomous community of Castilla-La Mancha, Spain. This facility serves a small population of 600 residents, reflecting the rural character of the area. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. Although the plant serves fewer than 2,000 people, secondary treatment ensures effective removal of organic matter and suspended solids before discharge. The plant is located inland, away from coastal areas. The local watershed ultimately drains into the Tagus River basin, which flows westward through Spain and Portugal to the Atlantic Ocean. The plant plays a role in protecting local water quality and the downstream aquatic environment.

The plant is situated in the Tagus River basin, one of the major river systems in the Iberian Peninsula. The Tagus River flows from its source in the Albarracín Mountains through central Spain and Portugal, discharging into the Atlantic Ocean near Lisbon. The local watershed supports diverse aquatic life and is an important ecological corridor. The plant's secondary treatment helps reduce nutrient and organic pollution, contributing to the health of the downstream river ecosystem.
