Overview
UGENA YELES ESQUIVIAS wastewater treatment plant serves Yeles, Toledo, in Castilla-La Mancha, Spain, handling a population equivalent of 26,000. The plant operates under Spain's implementation of the EU Urban Waste Water Treatment Directive.
UGENA YELES ESQUIVIAS is a wastewater treatment plant located in Yeles, a municipality in the province of Toledo, within the autonomous community of Castilla-La Mancha, Spain. The plant serves a population of approximately 26,000 people, placing it in the medium agglomeration category under EU classification. As a Spanish facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), transposed into national law via the Real Decreto-Ley 11/1995 and subsequent regulations. For agglomerations of this size, the directive requires at least secondary treatment, with tertiary treatment mandated if the receiving waters are designated as sensitive areas. Compliance with the directive ensures appropriate treatment standards. The treated effluent is discharged into the local hydrological network, which ultimately drains into the Tagus River basin. The Tagus River flows westward through central Spain and Portugal, emptying into the Atlantic Ocean near Lisbon. The plant plays a key role in protecting the Tagus watershed from untreated wastewater, supporting water quality for downstream communities and ecosystems.
Environmental context
The plant discharges into the Tagus River basin, one of the Iberian Peninsula's major river systems. The Tagus flows through central Spain and Portugal, supporting diverse aquatic life and providing water for agriculture and urban use. Downstream, the river forms the Tagus Estuary near Lisbon, a vital habitat for migratory birds and fish species. The plant's operations help maintain water quality in this ecologically significant watershed.
