EL TOBOSO Wastewater Treatment Plant, El Toboso, Castilla-La Mancha, Spain

EL TOBOSO is a wastewater treatment plant located in the municipality of El Toboso, in the province of Toledo, Castilla-La Mancha, Spain. The plant serves a population of approximately 3,639 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). It is situated inland, far from coastal areas, and its treated effluent is discharged into local watercourses that ultimately drain into the Tagus River basin. As a secondary treatment facility, EL TOBOSO meets the standard requirements for organic matter and suspended solids removal as mandated by the EU UWWTD for agglomerations of this size. The plant's discharge volume of 506.00 cubic meters per day reflects the typical flow for a community of this scale. The plant operates under Spain's national implementation of the directive, which ensures compliance with EU environmental standards. The treated wastewater from EL TOBOSO is discharged into the local hydrological network, which flows into the Tagus River, one of the Iberian Peninsula's major rivers. The Tagus River supports diverse aquatic ecosystems and provides water for agriculture and human consumption downstream. The plant's secondary treatment helps protect the river's water quality by reducing pollutant loads before discharge, contributing to the overall health of the Tagus basin.

EL TOBOSO discharges treated wastewater into local streams that feed into the Tagus River basin. The Tagus River flows westward through central Spain and into Portugal, eventually reaching the Atlantic Ocean near Lisbon. The river supports a variety of aquatic life, including fish species such as barbel and nase, and its floodplains provide important habitats for migratory birds. Secondary treatment at the plant helps mitigate nutrient and organic pollution, safeguarding the ecological integrity of the downstream water bodies.
