The plant serves a population of 37,178, placing it in the medium agglomeration category under EU regulations. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size discharging into coastal waters. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), and it is situated within 50 km of the coast, indicating a marine discharge. The plant's treated effluent is discharged into the Mediterranean Sea, specifically into the Bay of Palma. This coastal area supports diverse marine life, including seagrass meadows and fish populations, and is an important ecological zone. The plant plays a key role in protecting the local marine environment from untreated wastewater.

The plant discharges into the Mediterranean Sea via the Bay of Palma, a coastal area that supports seagrass meadows (Posidonia oceanica) and diverse marine species. The bay is a vital ecological and economic resource for the Balearic Islands, and the plant's treatment helps maintain water quality for tourism and marine life.
