SA COMA Wastewater Treatment Plant, Son Moro, Illes Balears, Spain

SA COMA is a wastewater treatment plant located in Son Moro, within the municipality of Sant Llorenç des Cardassar on the island of Mallorca, Illes Balears, Spain. The plant serves a population equivalent of approximately 40,877, classifying it as a medium-sized agglomeration under EU regulations. Its coastal location places it in a sensitive area requiring advanced treatment to protect marine ecosystems. As a Spanish facility, SA COMA operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for inland plants and more stringent tertiary treatment for discharges into sensitive areas such as coastal waters. The regulatory framework ensures that the plant meets required effluent standards to minimize environmental impact. The treated effluent from SA COMA is discharged into the Mediterranean Sea, which is a sensitive marine environment supporting diverse aquatic life and tourism. The Balearic Islands rely on proper wastewater management to preserve water quality for bathing, fishing, and marine biodiversity. The plant plays a key role in protecting the coastal waters of eastern Mallorca from nutrient pollution and pathogens.

The plant discharges into the Mediterranean Sea near the eastern coast of Mallorca. This coastal area supports seagrass meadows, fish nurseries, and migratory bird species. The Balearic Islands' marine environment is ecologically sensitive, requiring high treatment standards to prevent eutrophication and protect biodiversity. The receiving waters ultimately connect to the broader Mediterranean basin, a semi-enclosed sea with limited water exchange.
