Overview
SOLSONA wastewater treatment plant serves the city of Solsona in Catalunya, Spain, with a population equivalent of 8,337. The plant discharges treated effluent into the local river system, contributing to the protection of the Ebro basin.
The SOLSONA wastewater treatment plant is located in Solsona, a town in the province of Lleida, within the autonomous community of Catalunya, Spain. Serving a population of approximately 8,337, the plant is part of the municipal wastewater infrastructure for this inland community. As a plant of this scale in Spain, SOLSONA operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary treatment for agglomerations with a population equivalent between 2,000 and 10,000, which applies to Solsona. The plant's treatment process is designed to meet these standards, ensuring compliance with European regulations. The treated wastewater from SOLSONA is discharged into a local watercourse that ultimately drains into the Ebro River basin, one of the most important river systems in Spain. The Ebro River flows into the Mediterranean Sea, supporting diverse aquatic life and agricultural activities along its course. The plant plays a key role in protecting downstream water quality and the ecological health of the basin.
Environmental context
The SOLSONA plant discharges into a tributary of the Ebro River, which flows through northeastern Spain and empties into the Mediterranean Sea via the Ebro Delta. The Ebro basin supports a variety of habitats, including wetlands and riparian forests, and is an important migratory corridor for birds. The plant's operations help maintain water quality in this ecologically sensitive watershed.

The plant serves a population equivalent of approximately 8,337 people, making it a medium-sized agglomeration under EU classification.
The treated wastewater is discharged into a local watercourse that flows into the Ebro River basin, eventually reaching the Mediterranean Sea.
Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving populations between 2,000 and 10,000, like SOLSONA, are required to provide secondary treatment. Spain has transposed this directive into national law, and the plant operates under this regulatory framework.
For agglomerations of this size, Spanish regulations mandate secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. Some plants may also incorporate nutrient removal if discharging into sensitive areas.
