MEJORADA SEGURILLA Wastewater Treatment Plant, Mejorada, Spain

MEJORADA SEGURILLA is a wastewater treatment plant located in Mejorada, Toledo, within the autonomous community of Castilla-La Mancha, Spain. The plant serves a population of approximately 6,970 residents, classifying it as a small to medium agglomeration under Spanish and EU regulations. The plant operates with secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with discharge standards. The treated effluent is discharged into local watercourses that ultimately drain into the Tagus River basin, a major river system in Spain. The Tagus River flows westward through central Spain and into Portugal, discharging into the Atlantic Ocean near Lisbon. The plant's operations contribute to protecting the ecological health of the Tagus basin and downstream environments.

The plant discharges into the Tagus River basin, one of the Iberian Peninsula's largest river systems. The Tagus flows through diverse landscapes, including agricultural and urban areas, before reaching the Atlantic Ocean. The basin supports a variety of aquatic life and is an important resource for irrigation and drinking water. Proper wastewater treatment is essential to prevent nutrient pollution and maintain water quality in this ecologically sensitive region.
