Overview
Artesa de Segre wastewater treatment plant in Catalunya, Spain, serves 2,967 people with advanced treatment. It discharges 532.05 m³/day and has a designed capacity of 3,203.00 m³/day.
The Artesa de Segre wastewater treatment plant is located in the municipality of Artesa de Segre, in the Noguera comarca of Catalunya, Spain. It serves a population of approximately 2,967 residents, classifying it as a small agglomeration under Spanish and EU regulations. The plant is situated inland, away from coastal areas, and treats municipal wastewater from the local community. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. It has a designed capacity of 3,203.00 m³/day and currently discharges an average volume of 532.05 m³/day, indicating significant spare capacity. The facility operates under Spain's national water regulations, which transpose EU directives and are enforced by regional authorities in Catalunya. The treated effluent is discharged into a local watercourse that ultimately flows into the Segre River, a major tributary of the Ebro River. The Ebro River basin is one of Spain's most important hydrological systems, supporting diverse aquatic life and agricultural activities. The advanced treatment helps protect downstream water quality in the Segre and Ebro rivers, contributing to the ecological health of the Mediterranean Sea, where the Ebro River ends.
Environmental context
The plant discharges into a local stream that feeds into the Segre River, which flows through the Noguera region before joining the Ebro River. The Ebro River basin is a critical ecological corridor in northeastern Spain, supporting species such as the European eel and various migratory birds. The advanced treatment ensures minimal nutrient and pollutant loading, protecting the downstream riverine and estuarine ecosystems.
