Moron de la Frontera Wastewater Treatment Plant, Andalusia, Spain

Moron de la Frontera wastewater treatment plant is located in the municipality of Moron de la Frontera, in the province of Seville, Andalusia, Spain. The plant serves a population of approximately 45,500 people, classifying it as a medium-sized agglomeration under EU regulations. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations with a population equivalent between 10,000 and 150,000. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Guadalquivir River basin, which flows into the Atlantic Ocean at the Gulf of Cadiz. The Guadalquivir River supports diverse aquatic life and is an important ecological corridor in southern Spain.

The plant discharges into the Guadalquivir River basin, which flows through Andalusia and empties into the Atlantic Ocean at the Gulf of Cadiz. The Guadalquivir River supports a variety of fish species and provides habitat for migratory birds. The region's Mediterranean climate with seasonal droughts makes water quality management critical for downstream ecosystems.
