Overview
San Carlos del Valle wastewater treatment plant serves 2,106 people in Castilla-La Mancha, Spain, with secondary treatment. It discharges 265 m³/day, operating under EU Urban Waste Water Treatment Directive standards.
The San Carlos del Valle wastewater treatment plant is located in the municipality of San Carlos del Valle, in the province of Ciudad Real, Castilla-La Mancha, Spain. It serves a population of approximately 2,106 residents, classifying it as a small agglomeration under EU regulations. The plant is situated inland, far from coastal areas, and its operations are part of the regional wastewater infrastructure managed by local authorities. The plant provides secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a reported discharge volume of 265 cubic meters per day, indicating consistent operation. The treated effluent is discharged into local watercourses that eventually drain into the Guadiana River basin, a major hydrological system in central Spain. The Guadiana River flows westward through Extremadura and into the Atlantic Ocean at the Gulf of Cádiz. The plant's operations help protect the ecological health of these inland waters, supporting biodiversity and water quality in the region.
Environmental context
The plant discharges into the Guadiana River basin, which drains into the Atlantic Ocean via the Gulf of Cádiz. The Guadiana is a vital water resource for agriculture and ecosystems in central and southwestern Spain. The receiving waters support diverse aquatic life, including fish species such as barbel and carp, and provide habitat for migratory birds. Effective wastewater treatment is essential to prevent nutrient enrichment and maintain water quality in this semi-arid region.
