Overview
Cumbres Mayores wastewater treatment plant in Andalucía, Spain, serves a population of 3,004 with secondary treatment. It discharges 544.47 m³/day of treated effluent, operating under EU Urban Waste Water Treatment Directive standards.
Cumbres Mayores wastewater treatment plant is located in the Sierra de Huelva region of Andalucía, Spain, serving the small municipality of Cumbres Mayores. The plant provides secondary treatment for a population equivalent of 3,004, reflecting its role in managing domestic wastewater for this rural community. As a secondary treatment facility, the plant meets the minimum requirements under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for populations between 2,000 and 10,000 in inland areas, ensuring organic matter and suspended solids are effectively reduced before discharge. The treated effluent volume of 544.47 m³/day is discharged into local watercourses that drain into the Guadiana River basin, eventually reaching the Gulf of Cádiz in the Atlantic Ocean. The plant's operation helps protect the region's water quality and supports the ecological health of downstream aquatic habitats.
Environmental context
The plant discharges into local streams that are part of the Guadiana River basin, one of the major Iberian river systems. The Guadiana flows southward through Spain and Portugal, forming part of the border before emptying into the Gulf of Cádiz. This watershed supports diverse aquatic life and is important for migratory fish species. The secondary treatment provided by the plant helps reduce nutrient and organic loads, mitigating eutrophication risks in downstream water bodies.
