Plouër-sur-Rance La Minotais Wastewater Treatment Plant, Brittany, France

Plouër-sur-Rance La Minotais is an advanced wastewater treatment plant located in Plouër-sur-Rance, a commune in the Côtes-d'Armor department of Brittany, France. The plant serves a population of approximately 3,426 and has a designed capacity of 3,000 cubic meters per day, with an actual discharge volume of 611.19 cubic meters per day. It is situated near the Rance River, close to the coast. As an advanced treatment facility, the plant provides a higher level of purification than secondary treatment, typically including nutrient removal. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations between 2,000 and 10,000 population equivalent in sensitive areas are required to have more stringent treatment. The advanced level here aligns with the directive's goals for protecting the sensitive coastal waters of the Rance estuary and the English Channel. The plant's treated effluent is discharged into the Rance River, which flows into the Rance estuary and then into the English Channel. The estuary is an ecologically important area supporting diverse aquatic life, including migratory fish species. By employing advanced treatment, the plant helps minimize nutrient loading and protects the downstream marine environment.

The plant discharges into the Rance River, which flows into the Rance estuary and then into the English Channel. The estuary is a dynamic coastal ecosystem that supports diverse aquatic life, including fish, shellfish, and migratory birds. Advanced treatment helps reduce nutrient pollution, safeguarding water quality in this sensitive coastal zone.
