The treated wastewater is discharged into the local environment near the Mediterranean Sea. The plant plays a key role in protecting coastal water quality and supporting the ecological health of the nearby marine environment, which is important for tourism and local biodiversity.

The plant discharges treated effluent into the Mediterranean Sea near l'Ametlla de Mar, a coastal town in Catalonia. The receiving waters are part of the Balearic Sea, which supports diverse marine life including seagrass meadows and fish populations. The plant's secondary treatment helps reduce nutrient loading, mitigating the risk of eutrophication in this sensitive coastal ecosystem.
