Overview
LLEIDA wastewater treatment plant serves the city of Lleida in Catalunya, Spain, with a population equivalent of approximately 168,284. It operates under the EU Urban Waste Water Treatment Directive, ensuring compliance with secondary treatment stand
The LLEIDA wastewater treatment plant is located in Lleida, in the autonomous community of Catalunya, Spain. It serves a population equivalent of approximately 168,284, classifying it as a large agglomeration under EU regulations. The plant is situated inland, away from coastal areas, and its treated effluent is discharged into the local river system. As a large agglomeration, the plant is required to meet secondary treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). The regulatory framework ensures that treatment levels are appropriate for the population served. The plant's discharge ultimately flows into the Ebro River basin, which drains into the Mediterranean Sea. The Ebro River is one of Spain's most significant watercourses, supporting diverse aquatic ecosystems and agricultural activities. The plant plays a crucial role in protecting water quality in the region, particularly downstream in the Ebro Delta, an ecologically sensitive area.
Environmental context
The LLEIDA plant discharges into the Segre River, a tributary of the Ebro River, which flows into the Mediterranean Sea. The Ebro River basin supports a variety of aquatic life and is an important migratory corridor for fish species. Downstream, the Ebro Delta is a ecologically sensitive wetland area that relies on good water quality from upstream sources. The plant's treatment performance is critical to maintaining the health of this downstream environment.
Frequently asked questions
The LLEIDA plant is located at Camí del Sot de Fontanet, Sant Ignasi, Lleida, in the province of Segrià, Catalunya, Spain.
The plant serves a population equivalent of approximately 168,284 people, classifying it as a large agglomeration under EU regulations.
The treated effluent is discharged into the Segre River, which is a tributary of the Ebro River. The Ebro River ultimately flows into the Mediterranean Sea.
As a Spanish plant serving over 150,000 people, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment and, if in a sensitive area, tertiary treatment.
For large agglomerations in Spain, secondary treatment is standard. In sensitive areas like the Ebro basin, tertiary treatment may be required to reduce nutrients and protect downstream ecosystems.
