PUEBLA DE HIJAR LA Wastewater Treatment Plant, La Puebla de Híjar, Aragón

PUEBLA DE HIJAR LA is a wastewater treatment plant located in La Puebla de Híjar, a municipality in the Bajo Martín comarca of Aragón, Spain. The plant serves a population of approximately 1,369 people, reflecting its role in managing domestic wastewater for this small inland community. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids. The plant has a designed capacity of 9,167 m³/day, with an actual discharge volume of 248.13 m³/day, indicating significant spare capacity. The treated effluent is discharged into a local watercourse within the Ebro River basin, which ultimately drains into the Mediterranean Sea. The plant's operation contributes to protecting the ecological health of the Ebro River system and downstream coastal waters, supporting biodiversity and water quality in the region.

The plant discharges into a tributary of the Ebro River, which flows through Aragón and Catalonia before reaching the Mediterranean Sea. The Ebro basin supports diverse aquatic life and is an important agricultural and ecological corridor. Downstream, the Ebro Delta is a sensitive wetland area that relies on adequate water quality for its rich birdlife and fisheries.
