Environmental context
SANT CELONI discharges into the Tordera River basin, which flows into the Mediterranean Sea near the Maresme coast. The river supports diverse aquatic habitats and is an important corridor for migratory fish. The plant's treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the coastal waters of the Catalan Sea.
