Overview
TORDESILLAS wastewater treatment plant serves the municipality of Tordesillas in Castilla y León, Spain. It treats wastewater for approximately 17,250 people under the EU Urban Waste Water Treatment Directive.
The TORDESILLAS wastewater treatment plant is located in Tordesillas, a town in the province of Valladolid, within the autonomous community of Castilla y León, Spain. The plant serves a population of approximately 17,250 residents, classifying it as a medium-sized agglomeration under EU regulations. Its location along the Autovía de Castilla places it in a region characterized by a continental Mediterranean climate with agricultural and urban influences. As a Spanish wastewater facility, the plant 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. The plant is expected to comply with national regulations transposing the directive, ensuring appropriate treatment before discharge. The treated effluent from the plant is discharged into the local hydrological network, which ultimately drains into the Duero River basin. The Duero River flows westward through Spain and Portugal, emptying into the Atlantic Ocean near Porto. The plant plays a key role in protecting the water quality of the Duero basin, supporting aquatic life and downstream water uses such as agriculture and recreation.
Environmental context
The TORDESILLAS plant discharges into the Duero River basin, one of the major river systems in the Iberian Peninsula. The Duero River flows through the Castilla y León region, supporting diverse aquatic ecosystems and providing water for irrigation and human consumption. Downstream, the river enters Portugal and eventually reaches the Atlantic Ocean. The plant's operations help maintain the ecological health of this watershed, particularly in a region where agricultural runoff and urban discharges can impact water quality.
