CELRA Wastewater Treatment Plant, Medinyà, Catalunya, Spain

CELRA is a wastewater treatment plant located in Medinyà, within the municipality of Sant Julià de Ramis, in the Gironès comarca of Girona, Catalunya, Spain. The plant serves a population of 6,598, placing it in the small agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). As a Spanish facility, CELRA operates under the national transposition of the EU UWWTD (Directive 91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into freshwater or estuaries. The plant's treated effluent likely discharges into a local watercourse within the Ter River basin, which flows into the Mediterranean Sea near the Costa Brava. This region supports diverse aquatic life and is ecologically sensitive due to its coastal and agricultural significance.

CELRA's treated wastewater likely discharges into a tributary of the Ter River, which flows into the Mediterranean Sea at the Costa Brava.
