Campanet Wastewater Treatment Plant - Illes Balears, Spain

Campanet wastewater treatment plant is located in the municipality of Campanet, in the Raiguer region of Illes Balears, Spain. The plant serves a population of 2,751 and is situated near the Autopista Palma - sa Pobla. It operates under Spain's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for wastewater collection and treatment. The plant provides advanced treatment, which goes beyond the secondary treatment typically required for agglomerations under 10,000 population equivalent. Its designed capacity is 4,000 m³/day, and the current discharge volume is 768.27 m³/day. Advanced treatment often includes nutrient removal to protect sensitive receiving waters. The plant is within 10 km of the coast, discharging treated wastewater into the Mediterranean Sea watershed. The local environment includes coastal ecosystems that benefit from the advanced treatment, reducing nutrient loads and protecting marine water quality. The plant plays a key role in safeguarding the Balearic coastal environment.

The plant's treated effluent ultimately reaches the Mediterranean Sea, a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The Balearic coastal zone supports seagrass meadows (Posidonia oceanica) and diverse marine life. Advanced treatment helps minimize eutrophication risks and protects these ecologically important habitats.
