PUERTOLLANO GUADALQUIVIR Wastewater Treatment Plant, Puertollano, Castilla-La Mancha

PUERTOLLANO GUADALQUIVIR is a wastewater treatment plant located in Puertollano, a city in the province of Ciudad Real, within the autonomous community of Castilla-La Mancha, Spain. The plant serves a population of approximately 100,000 people, classifying it as a large agglomeration under EU standards. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. Compliance with EU standards ensures appropriate treatment for its population tier. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Guadalquivir River basin. The Guadalquivir River flows through southern Spain and empties into the Atlantic Ocean at the Gulf of Cádiz. This river system supports diverse aquatic life and is important for agriculture and water supply in the region.

The plant discharges into the Guadalquivir River basin, which flows through Andalusia and into the Atlantic Ocean at the Gulf of Cádiz. The Guadalquivir is a major river supporting wetlands and estuaries that are ecologically sensitive, providing habitat for migratory birds and fish species. The plant's operations are crucial for protecting downstream water quality in this important watershed.
