Binaced Wastewater Treatment Plant - Serving Binaced, Huesca, Aragón, Spain

The Binaced wastewater treatment plant is located in the municipality of Binaced, within the province of Huesca in the autonomous community of Aragón, Spain. The facility serves a population equivalent of approximately 22,708, classifying it as a medium-sized agglomeration under European Union regulations. Its operations are governed by Spanish national legislation transposing the EU Urban Waste Water Treatment Directive (91/271/EEC). As a plant serving a population between 10,000 and 100,000, the EU directive requires secondary treatment as a minimum standard. The regulatory framework ensures compliance with effluent quality standards for biological oxygen demand, suspended solids, and other parameters. The plant's capacity and operational status are consistent with typical municipal infrastructure for a town of this size in inland Spain. The treated effluent from Binaced is discharged into the local hydrological network, ultimately contributing to the Ebro River basin. The Ebro River is one of Spain's major watercourses, flowing into the Mediterranean Sea via the Ebro Delta, a region of significant ecological importance. The plant plays a key role in protecting local water quality and supporting the environmental health of the downstream aquatic ecosystems.

The Binaced plant discharges into the Cinca River, a tributary of the Segre River, which flows into the Ebro River. The Ebro River basin supports diverse aquatic life and is an important agricultural and ecological corridor in northeastern Spain. The downstream Ebro Delta is a critical wetland area for migratory birds and fish species, making effective wastewater treatment essential for maintaining water quality and biodiversity in the region.
