ALFARRAS ALMENAR Wastewater Treatment Plant, Andaní, Catalunya

ALFARRAS ALMENAR is a wastewater treatment plant located in Andaní, a locality within the municipality of Alfarràs, in the Segrià comarca of Catalunya, Spain. The plant serves a population of approximately 5,485 people, placing it in the small to medium agglomeration category under European Union classifications. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size discharging into freshwater or estuaries. Compliance with the directive ensures appropriate treatment standards are met. The treated effluent from the plant is discharged into local watercourses that ultimately flow into the Ebro River, one of the most important rivers in the Iberian Peninsula. The Ebro River supports diverse aquatic ecosystems and is a vital resource for agriculture and communities in the region. The plant plays a key role in protecting water quality in this sensitive Mediterranean watershed.

The plant discharges into tributaries of the Ebro River, which flows into the Mediterranean Sea via the Ebro Delta, a highly productive and ecologically sensitive area. The Ebro basin supports diverse aquatic life, including migratory fish species, and the delta is an important habitat for waterbirds. Proper wastewater treatment is essential to prevent nutrient enrichment and maintain the ecological balance of this downstream environment.
