MONTEJICAR Wastewater Treatment Plant, Montejícar, Andalucía, Spain

MONTEJICAR is a wastewater treatment plant located in Montejícar, a municipality in the Comarca de Los Montes, Granada, Andalucía, Spain. The plant serves a population of approximately 3,000 residents, providing essential sanitation services for this inland community. The facility employs 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. With a designed capacity of 4,000 m³/day and an average discharge volume of 543.74 m³/day, the plant operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into local watercourses that eventually drain into the Guadalquivir River basin, which flows into the Atlantic Ocean via the Gulf of Cádiz. The plant plays a key role in protecting the ecological health of the region's rivers and supporting downstream water quality.

The plant discharges into local streams that are part of the Guadalquivir River basin, one of Spain's major river systems. The Guadalquivir flows through Andalucía and empties into the Gulf of Cádiz, supporting diverse aquatic habitats and agricultural water use. The treatment plant helps reduce nutrient and pollutant loads, protecting sensitive freshwater ecosystems in the region.
