Overview
PENARROYA PUEBLO NUEVO is a wastewater treatment plant in Peñarroya-Pueblonuevo, Andalucía, Spain, serving approximately 24,900 people. It operates under Spain's implementation of the EU Urban Waste Water Treatment Directive.
PENARROYA PUEBLO NUEVO is a wastewater treatment plant located in Peñarroya-Pueblonuevo, a municipality in the province of Córdoba, Andalucía, Spain. The plant serves a population of approximately 24,900, classifying it as a medium-sized agglomeration under EU classification. 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 discharging into freshwater. Spain's transposition of the directive sets specific standards for effluent quality and monitoring, enforced by regional authorities in Andalucía. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Guadalquivir River basin, one of Spain's major river systems. The Guadalquivir flows through Andalucía to the Atlantic Ocean at the Gulf of Cádiz, supporting diverse aquatic ecosystems and agricultural irrigation along its course.
Environmental context
The plant discharges into the Guadalquivir River basin, which flows through southern Spain to the Atlantic Ocean. The Guadalquivir supports important wetlands and migratory bird habitats, including the Doñana region. Nutrient management is critical to prevent eutrophication in downstream reservoirs and coastal waters.
