CANET EN ROUSSILLON Wastewater Treatment Plant, Canet-en-Roussillon, Occitanie

The CANET EN ROUSSILLON wastewater treatment plant is located in Canet-en-Roussillon, a coastal commune in the Pyrénées-Orientales department of Occitanie, southern France. The plant serves a population of around 42,297, placing it in the medium agglomeration category under European Union regulations. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide at least secondary treatment, with more stringent requirements if the discharge enters a sensitive area. The facility operates within France's national regulatory framework, which implements the EU directive through the French Public Health Code and water management laws. The plant discharges treated wastewater into the Mediterranean Sea, as it is located within 50 km of the coast. The local watershed includes the Têt River and other coastal streams that drain into the Gulf of Lion. The receiving environment supports diverse marine life and is important for regional tourism and fisheries. Proper treatment is essential to protect coastal water quality and the ecological health of the Mediterranean.

The plant's treated effluent ultimately reaches the Mediterranean Sea via the Gulf of Lion, a key marine area supporting diverse ecosystems including seagrass meadows and fish nurseries. The local watershed includes the Têt River and smaller coastal streams that drain the Pyrenean foothills. Discharge into this sensitive coastal environment requires effective nutrient removal to prevent eutrophication and protect marine biodiversity.
