Villanueva de Córdoba Wastewater Treatment Plant, Andalucía, Spain

The Villanueva de Córdoba wastewater treatment plant is located in the province of Córdoba, within the autonomous community of Andalucía, Spain. It serves the town of Villanueva de Córdoba, which has a population of around 9,263. The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. As a facility serving a medium-sized agglomeration, the plant is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC. This directive requires secondary treatment for agglomerations with a population equivalent between 2,000 and 10,000, unless the receiving waters are designated as sensitive areas, which may necessitate more advanced treatment. It operates within this regulatory framework. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Guadalquivir River basin, which flows into the Atlantic Ocean. The Guadalquivir basin supports diverse aquatic life and is an important ecological corridor in southern Spain. The plant's operations help protect the water quality of these downstream environments.

The plant discharges into the Guadalquivir River basin, which flows through Andalucía and empties into the Atlantic Ocean at the Gulf of Cádiz. This basin supports a variety of aquatic species and is an important migratory route for birds. The treatment plant helps maintain water quality in the region, reducing nutrient and pollutant loads that could otherwise impact downstream ecosystems and the sensitive Doñana area.
