TABARA Wastewater Treatment Plant, Tábara, Castilla y León, Spain

TABARA is a wastewater treatment plant located in Tábara, a municipality in the province of Zamora, within the autonomous community of Castilla y León, Spain. The plant serves a population of approximately 2,000 people, classifying it as a small agglomeration under Spanish and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity is 2,000 cubic meters per day, and the current discharge volume is 170.70 cubic meters per day, indicating ample reserve capacity. The treated effluent is discharged into a local watercourse that ultimately drains into the Duero River basin, one of the major river systems in the Iberian Peninsula. The Duero flows westward through Spain and Portugal, emptying into the Atlantic Ocean near Porto. The plant's operation helps protect the local aquatic environment and downstream water quality.

The plant discharges into a tributary of the Duero River basin, which flows through the Castilla y León region and into Portugal. The Duero River supports diverse aquatic life and is an important ecological corridor in the Iberian Peninsula. The surrounding area is predominantly agricultural, and the plant's secondary treatment helps reduce nutrient and organic loads, mitigating eutrophication risks in downstream water bodies.
