CARCABUEY Wastewater Treatment Plant, Carcabuey, Andalucía, Spain

The CARCABUEY wastewater treatment plant is located in Carcabuey, a town in the province of Córdoba, Andalucía, Spain. The facility provides secondary treatment for a population of around 4,711 residents, with a designed capacity of 3,033 cubic meters per day and an average daily discharge of 853.86 cubic meters. As a secondary treatment plant in Spain, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 10,000. The plant's capacity and discharge volumes align with the needs of a small to medium-sized agglomeration. The treated effluent is discharged into a local watercourse that eventually drains into the Guadalquivir River basin, which flows into the Atlantic Ocean at the Gulf of Cádiz. The plant plays a key role in protecting the water quality of the surrounding environment and downstream ecosystems.

The CARCABUEY plant discharges into a local stream that is part of the Guadalquivir River basin. The Guadalquivir River flows through Andalucía and empties into the Gulf of Cádiz in the Atlantic Ocean. The downstream environment supports diverse aquatic life and is important for regional biodiversity, including migratory bird species that rely on the river's wetlands.
