Overview
CASSA DE LA SELVA wastewater treatment plant serves Sant Andreu Salou in Catalunya, Spain, with a designed capacity of 1.00 and a population served of 12,084.
CASSA DE LA SELVA is a wastewater treatment plant located in Sant Andreu Salou, within the Gironès comarca of Girona, Catalunya, Spain. The plant serves a population of 12,084, placing it in the medium-agglomeration category under EU classification. Under the EU Urban Waste Water Treatment Directive 91/271/EEC, agglomerations of this size (between 10,000 and 150,000 population equivalent) are generally required to achieve secondary treatment as a minimum standard. It operates within Spain's national regulatory framework, which transposes the EU directive into law. Compliance is overseen by regional authorities in Catalunya. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. The region's rivers and streams support diverse aquatic life and contribute to the ecological health of the coastal environment. Proper treatment helps protect downstream water quality and marine ecosystems.
Environmental context
The plant discharges into the local watershed in the Gironès region, which flows through the Ter River basin before reaching the Mediterranean Sea. This coastal area supports diverse marine life and is ecologically sensitive, requiring effective wastewater treatment to prevent nutrient enrichment and protect water quality.
