The FUENTESAUCO wastewater treatment plant is located in Fuentesaúco, a municipality in the province of Zamora, within the autonomous community of Castilla y León, Spain. The plant serves a population equivalent of 11,040, placing it in the medium agglomeration category under European Union regulations. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size discharging into inland waters. The directive also requires appropriate treatment to protect receiving water bodies, with tertiary treatment in sensitive areas. The plant's location inland, away from coastal zones, aligns with standard regulatory requirements for freshwater discharge. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Duero River basin, a major hydrological system in northwestern Spain. The Duero River flows westward into Portugal and empties into the Atlantic Ocean at Porto. The plant plays a key role in protecting the ecological health of the Duero basin, supporting aquatic life and downstream water quality.
Environmental context
The FUENTESAUCO plant discharges into tributaries of the Duero River, which flows through the Castilla y León region into Portugal and reaches the Atlantic Ocean. The Duero basin supports diverse aquatic ecosystems and is an important agricultural and ecological corridor. The plant's treatment helps maintain water quality in this transboundary river system, reducing nutrient loads and protecting downstream habitats.
