Overview
Trévou-Tréguignec's advanced wastewater treatment plant serves 2,380 people in Brittany, France. It discharges treated effluent near the coast, operating under EU Urban Waste Water Treatment Directive standards.
The TREVOU TREGUIGNEC_TRESTEL wastewater treatment plant serves the commune of Trévou-Tréguignec in the Côtes-d'Armor department of Brittany, France. With a population equivalent of 2,380, it is classified as a small agglomeration under French regulations. The plant is situated near the coast, less than 10 km from the English Channel. The facility employs advanced treatment processes, exceeding the EU Urban Waste Water Treatment Directive's minimum requirement of secondary treatment for agglomerations of this size. It has a designed capacity of 4,000 cubic meters per day and currently treats an average daily volume of 424.59 cubic meters, indicating significant spare capacity. The plant's advanced treatment likely includes nutrient removal to protect sensitive coastal waters. Treated effluent is discharged into the local watershed, which drains into the English Channel via small coastal streams. The receiving environment supports diverse marine life and is part of the broader Brittany coastal ecosystem, known for its rocky shores and rich biodiversity. The plant's advanced treatment helps minimize nutrient loading and protect downstream water quality.
Environmental context
The plant discharges into the coastal watershed of the English Channel, specifically near the Baie de Lannion. This area supports diverse marine habitats, including seagrass beds and rocky reefs, and is an important migratory corridor for seabirds. Advanced treatment reduces nutrient and pollutant loads, helping to protect the sensitive coastal ecosystem from eutrophication and maintaining water quality for tourism and fisheries.
