Overview
BENAVENTE wastewater treatment plant serves Villanueva de Azoague in Castilla y León, Spain, with a population equivalent of 32,000. It operates under the EU Urban Waste Water Treatment Directive.
The BENAVENTE wastewater treatment plant is located in Villanueva de Azoague, within the province of Zamora in the autonomous community of Castilla y León, Spain. The facility serves a population equivalent of 32,000, classifying it as a medium-sized agglomeration under European Union regulations. As a Spanish wastewater treatment plant, BENAVENTE operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Duero River basin. The Duero River flows westward through Spain and Portugal, emptying into the Atlantic Ocean at Porto. This river system supports diverse aquatic life and is important for regional agriculture and water supply.
Environmental context
The BENAVENTE plant discharges into the Duero River basin, a major Iberian watershed that flows into the Atlantic Ocean. The Duero River and its tributaries support diverse aquatic ecosystems, including fish species such as barbel and trout. The region's semi-arid climate makes water quality management critical for both ecological health and downstream agricultural use.
