CIUTADELLA NORTE Wastewater Treatment Plant, Ciutadella, Menorca, Spain

CIUTADELLA NORTE is a wastewater treatment facility located in Ciutadella on the island of Menorca, part of the Balearic Islands, Spain. The plant serves a population of around 14,392, placing it in the medium agglomeration category under EU regulations. It is situated near the coast, within 10 km of the Mediterranean Sea. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. With a designed capacity of 15,000 m³/day and an actual discharge volume of 980.17 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variability. As a Spanish facility, it operates under national regulations that transpose EU directives, with permits issued by the regional water authority. The treated effluent is discharged into the Mediterranean Sea, likely via a marine outfall. The coastal waters around Menorca are ecologically sensitive, supporting seagrass meadows and diverse marine life. The plant's advanced treatment helps protect these ecosystems from nutrient pollution and other contaminants.
