Montemayor Wastewater Treatment Plant, Montemayor, Andalusia, Spain

The Montemayor wastewater treatment plant is located in the town of Montemayor, in the province of Córdoba, Andalusia, Spain. It serves a population of approximately 5,500 residents, making it a small-scale municipal facility. 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 biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 5,500 cubic meters per day, matching the population served, and reports a discharge volume of 996.86 cubic meters per day. The treated effluent is discharged into local watercourses that eventually drain into the Guadalquivir River basin. The Guadalquivir is a major river in southern Spain, flowing through Andalusia and into the Atlantic Ocean at the Gulf of Cádiz. The plant plays a role in protecting the water quality of these downstream environments, supporting aquatic life and agricultural water use in the region.

The plant discharges into local streams that are part of the Guadalquivir River basin, which ultimately drains into the Atlantic Ocean via the Gulf of Cádiz. The Guadalquivir basin supports diverse aquatic ecosystems and is important for irrigation in the region. The plant's secondary treatment helps reduce nutrient and organic pollution, contributing to the ecological health of downstream water bodies.
