The plant serves a population of approximately 5,974 people, classifying it as a small agglomeration under EU classification. Its location near the Mediterranean Sea places it in a sensitive coastal environment. 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 designed capacity is 1.00 cubic hectometer per year, indicating a modest scale appropriate for the local population. The regulatory framework ensures compliance with discharge standards. The plant's treated effluent likely discharges into the Mediterranean Sea, either directly or via a local watercourse, affecting the coastal waters of the Balearic Sea.

The plant plays a key role in protecting the local marine environment from nutrient pollution.
Environmental context
The plant discharges into the Mediterranean Sea near the southeastern coast of Mallorca. The receiving waters are part of the Balearic Sea, which supports ecologically sensitive habitats such as Posidonia oceanica seagrass meadows. These meadows provide critical nursery grounds for fish and help stabilize the seabed. Proper wastewater treatment is vital to prevent eutrophication and protect this marine ecosystem.
