Overview
SANTANYI wastewater treatment plant in Cala Santanyí, Illes Balears, Spain, serves 3,539 people with advanced treatment. It discharges 626.68 m³/day and has a designed capacity of 17,500 m³/day.
The SANTANYI wastewater treatment plant is located in Cala Santanyí, a coastal town on the island of Mallorca in the Illes Balears region of Spain. The plant serves a population of 3,539 and is situated near the Mediterranean coast, within 10 km of the shoreline. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity of 17,500 m³/day indicates it is sized to handle seasonal population fluctuations typical of tourist destinations in the Balearic Islands. The actual discharge volume is 626.68 m³/day, suggesting significant spare capacity. Treated effluent from the plant is discharged into the local environment, ultimately reaching the Mediterranean Sea. The coastal waters around Cala Santanyí support diverse marine life, including seagrass meadows and fish habitats. The plant's advanced treatment helps protect these sensitive marine ecosystems from nutrient pollution and other contaminants.
Environmental context
The plant discharges into the Mediterranean Sea near Cala Santanyí, a coastal area on the southeastern coast of Mallorca. The receiving waters are part of the Balearic Sea, which supports ecologically important habitats such as Posidonia oceanica seagrass meadows. These meadows provide nursery grounds for fish and help maintain water clarity. The advanced treatment level helps minimize nutrient loading and protects the coastal marine environment from eutrophication.
