Belmez Wastewater Treatment Plant, Belmez, Andalusia, Spain

Belmez wastewater treatment plant is located in the municipality of Belmez, in the province of Córdoba, Andalusia, Spain. The facility serves a population of approximately 5,380, classifying it as a small agglomeration under Spanish and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity of 5,380 cubic meters per day aligns with the population served, indicating adequate sizing. The plant's discharge volume is reported at 975.11 cubic meters, reflecting typical operational flows. The treated effluent is discharged into the local watercourse, which ultimately drains into the Guadalquivir River basin. This river system is ecologically significant, supporting diverse aquatic life and agricultural activities in southern Spain. The plant's operation helps protect downstream water quality in the Guadalquivir watershed.

The plant discharges into a tributary of the Guadalquivir River, one of Spain's major rivers flowing into the Gulf of Cádiz. The Guadalquivir basin supports a variety of ecosystems, including wetlands and estuaries that are important for migratory birds and fish species. The secondary treatment provided by the plant reduces organic pollutants and helps maintain the ecological balance of the receiving waters.
