Overview
Villamayor de Santiago wastewater treatment plant in Castilla-La Mancha, Spain, serves 4,264 people with advanced treatment. It discharges 691.00 cubic meters of treated wastewater daily.
The Villamayor de Santiago wastewater treatment plant is located in the municipality of Villamayor de Santiago, in the Castilla-La Mancha region of central Spain. The plant serves a population of 4,264 residents, making it a small-scale facility within the region's wastewater infrastructure. The plant employs advanced treatment processes, which go beyond the secondary treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment typically includes nutrient removal, ensuring high-quality effluent that meets stringent environmental standards. The treated wastewater is discharged into local watercourses that eventually drain into the Tagus River basin, one of the most important river systems in Spain. The advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region, which is characterized by a semi-arid climate and significant agricultural activity.
Environmental context
The plant discharges into the Tagus River basin, which flows westward through central Spain and Portugal before reaching the Atlantic Ocean near Lisbon. The Tagus River supports diverse aquatic life and is an important water source for irrigation and urban supply. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream habitats from eutrophication.
