San Pablo de los Montes Wastewater Treatment Plant - Advanced Treatment in Castilla-La Mancha

The San Pablo de los Montes wastewater treatment plant is located in the town of San Pablo de los Montes, in the province of Toledo, within the autonomous community of Castilla-La Mancha, Spain. The plant serves a population of approximately 4,867 residents, providing advanced treatment to ensure high-quality effluent. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. This level of treatment is typical for plants in sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires tertiary treatment for discharges into sensitive water bodies. The plant's daily discharge volume is 544 cubic meters. The treated effluent is discharged into local watercourses that eventually drain into the Tagus River basin, one of the most important river systems in the Iberian Peninsula. The Tagus River flows westward through Spain and Portugal, emptying into the Atlantic Ocean near Lisbon. The advanced treatment helps protect the ecological health of the downstream aquatic environment.

The plant discharges into local streams that are part of the Tagus River basin. The Tagus River supports diverse aquatic life and provides water for agriculture and human consumption. The advanced treatment level helps reduce nutrient loading, protecting downstream ecosystems from eutrophication. The region's Mediterranean climate with seasonal rainfall influences the river's flow regime.
