Cañete la Real Wastewater Treatment Plant, Andalucía, Spain

The Cañete la Real wastewater treatment plant is located in the municipality of Cañete la Real, in the province of Málaga, Andalucía, Spain. It serves a small population of 3,549 people, reflecting its role in a rural inland community. The plant is situated in the Guadalteba region, an area characterized by Mediterranean climate and agricultural activity. As a primary treatment facility, the plant provides basic physical treatment to remove settleable solids and some organic matter. While the designed capacity is 2,500 m³/day, the actual discharge volume is 643.25 m³/day, indicating operational headroom. Under Spanish and EU regulations, small agglomerations like this are subject to the Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment based on receiving water sensitivity. The treated effluent is discharged into local watercourses that ultimately drain into the Guadalquivir River basin, which flows into the Atlantic Ocean at the Gulf of Cádiz. The plant plays a key role in protecting local streams and groundwater from untreated sewage, supporting the ecological health of the region's Mediterranean watershed.

The plant discharges into small streams within the Guadalteba sub-basin, part of the larger Guadalquivir River system. The Guadalquivir flows westward through Andalucía and empties into the Atlantic Ocean at the Gulf of Cádiz, near Doñana. This watershed supports diverse aquatic life, including migratory fish species, and is ecologically sensitive due to agricultural runoff and seasonal water scarcity. The plant's primary treatment helps reduce organic load but may not fully address nutrient pollution, which is a concern in Mediterranean rivers.
