TORRES Wastewater Treatment Plant, Torres, Andalucía, Spain

TORRES is a municipal wastewater treatment plant located in Torres, a town in the province of Jaén, Andalucía, Spain. The plant serves a population of about 3,000 people, reflecting its role in managing domestic wastewater for this small inland community. It is situated along the Carretera de Acceso a Torres, within the rural landscape of southern Spain. The plant operates with secondary treatment, which is the standard biological process required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids. The designed capacity of 3,000 m³/day matches the population served, and the actual discharge volume of 543.74 m³/day indicates operational headroom. The treated effluent is discharged into a local watercourse, likely a tributary of the Guadalquivir River basin, which ultimately flows into the Atlantic Ocean via the Gulf of Cádiz. The plant's operation helps protect the ecological health of the receiving waters and downstream environments, supporting aquatic life and water quality in the region.

The plant discharges into a local stream that feeds into the Guadalquivir River basin, one of Spain's major river systems. The Guadalquivir flows through Andalucía and empties into the Gulf of Cádiz (Atlantic Ocean). The downstream environment includes agricultural areas and ecologically sensitive wetlands such as the Doñana region, which relies on good water quality for its diverse bird and aquatic species. Secondary treatment reduces organic pollution, helping to maintain the ecological balance of the river and its estuary.
