Overview
SAN JUSTO DE LA VEGA wastewater treatment plant serves the municipality of San Justo de la Vega in Castilla y León, Spain. It treats wastewater from approximately 6,000 residents.
SAN JUSTO DE LA VEGA is a wastewater treatment plant located in the municipality of San Justo de la Vega, in the province of León, within the autonomous community of Castilla y León, Spain. The plant serves a population of approximately 6,000 people, reflecting the scale of a small agglomeration under EU classification. As a Spanish facility, the plant operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (between 2,000 and 10,000 population equivalent), the directive requires appropriate treatment, typically secondary treatment, to ensure compliance with effluent standards. The treated effluent is discharged into the local water environment, likely the nearby river (the area is traversed by the Río Tuerto, a tributary of the Órbigo River, which flows into the Esla River and eventually the Duero River). The Duero basin supports diverse aquatic life and is an important agricultural and ecological corridor in northwestern Spain.
Environmental context
The plant discharges into the Río Tuerto, a tributary of the Órbigo River, which joins the Esla River and ultimately drains into the Duero River. The Duero basin is a major hydrological system in Spain and Portugal, supporting irrigated agriculture and diverse freshwater ecosystems. The receiving waters are ecologically sensitive, particularly during low-flow periods, and require effective nutrient removal to prevent eutrophication.
