Overview
ALFAMEN wastewater treatment plant serves the municipality of Alfamén in Aragón, Spain. It operates under EU Urban Waste Water Treatment Directive 91/271/EEC, which mandates secondary treatment for agglomerations of this scale.
ALFAMEN is a wastewater treatment plant located in Alfamén, a municipality in the Campo de Cariñena comarca of Zaragoza province, Aragón, Spain. The plant serves a population of approximately 5,656 people, classifying it as a small to medium agglomeration under EU classification. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, transposed into national legislation. For agglomerations with a population equivalent between 2,000 and 10,000, the directive requires appropriate treatment (secondary or equivalent) to protect receiving waters. The plant's discharge is regulated by the relevant Spanish water authority, likely the Confederación Hidrográfica del Ebro, which oversees water quality in the region. The plant's treated effluent is discharged into local watercourses that eventually drain into the Ebro River basin. The Ebro River flows eastward into the Mediterranean Sea, forming a large delta that is ecologically significant for birdlife and aquatic species. The plant plays a key role in protecting downstream water quality in this semi-arid region of Spain.
Environmental context
The plant discharges into local tributaries of the Ebro River basin, which ultimately flows into the Mediterranean Sea via the Ebro Delta. The Ebro Delta is a critical wetland supporting diverse aquatic life and migratory birds. The plant's treatment helps maintain water quality in this ecologically sensitive downstream environment, particularly important given the region's agricultural water demands.
