Tablada Wastewater Treatment Plant, Sevilla, Andalucía, Spain

Tablada is a wastewater treatment plant located in the Tablada district of Sevilla, in the Andalucía region of Spain. It serves an estimated population of 105,000, classifying it as a large agglomeration under European Union regulations. The plant is situated near the Guadalquivir River, which flows through Sevilla and into the Atlantic Ocean. As a facility serving over 100,000 people, Tablada is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment as a minimum for such agglomerations. In sensitive areas, tertiary treatment may also be mandated to reduce nutrient pollution. The regulatory framework ensures compliance with discharge standards. The treated effluent from Tablada is discharged into the Guadalquivir River, which flows southwest through the Doñana wetlands and into the Gulf of Cádiz. This river supports diverse aquatic life and is an important migratory corridor for birds. The plant plays a key role in protecting water quality in the lower Guadalquivir basin and the adjacent Atlantic coastal environment.

Tablada discharges treated wastewater into the Guadalquivir River, which flows through the Doñana wetlands and into the Gulf of Cádiz in the Atlantic Ocean. The Guadalquivir basin supports diverse aquatic ecosystems, including fish species such as the Iberian barbel and migratory birds. The plant's operations help maintain water quality in this ecologically sensitive region, which is important for both local biodiversity and downstream marine habitats.
