Portillo de Toledo Wastewater Treatment Plant - Advanced Treatment in Castilla-La Mancha, Spain

Portillo de Toledo wastewater treatment plant is located in the municipality of Portillo de Toledo, in the province of Toledo, Castilla-La Mancha, Spain. The plant serves a population of approximately 3,402 residents, providing advanced treatment to protect local water quality. The plant operates under Spain's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. With advanced treatment, the facility goes beyond the standard secondary treatment, likely addressing nutrient removal to meet sensitive area requirements. The treated effluent is discharged into local watercourses that eventually drain into the Tagus River basin, one of the Iberian Peninsula's major river systems. The Tagus flows westward through Spain and Portugal, emptying into the Atlantic Ocean near Lisbon. The advanced treatment helps protect downstream ecosystems and water quality in this important basin.

The plant 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 and urban use. Advanced treatment at this plant helps reduce nutrient loading and protects downstream habitats, including estuarine and coastal environments.
