The treated effluent is released into the coastal waters of the Mediterranean Sea near the Bay of Alcúdia. This area supports diverse marine life and is important for local tourism and fishing. The plant plays a key role in protecting the coastal environment from untreated wastewater, helping to maintain water quality in a region known for its beaches and natural beauty.

The plant discharges into the Mediterranean Sea near the Bay of Alcúdia, a coastal area on the northeastern coast of Mallorca. The bay supports seagrass meadows and diverse marine species, making it ecologically sensitive. The treated effluent contributes to the overall water quality of the coastal zone, which is important for both local ecosystems and recreational use.
