VALVERDE DEL CAMINO Wastewater Treatment Plant, Valverde del Camino, Andalucía

The VALVERDE DEL CAMINO wastewater treatment plant is located in the municipality of Valverde del Camino, in the province of Huelva, Andalucía, Spain. The plant serves a population of approximately 20,709 residents, classifying it as a medium-sized agglomeration under EU classification. It is situated inland, more than 50 km from the coast, and its operations are subject to Spanish and European wastewater regulations. As a plant in the European Union, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant is expected to meet the directive's standards for secondary treatment or equivalent. The treated effluent is discharged into a local watercourse, which ultimately drains into the Atlantic Ocean via the Guadiana River basin or nearby coastal systems. The plant plays a key role in protecting the region's water resources, including the sensitive ecosystems of the Doñana area and the Gulf of Cádiz. Proper treatment helps maintain water quality in the surrounding agricultural and natural landscapes.

The plant discharges into a local stream that feeds into the Guadiana River basin, which flows into the Gulf of Cádiz and the Atlantic Ocean. This region supports diverse aquatic life and is an important migratory corridor for birds. The downstream environment includes ecologically sensitive areas that benefit from reduced nutrient and pollutant loads.
