Creully Wastewater Treatment Plant, Creully sur Seulles, Normandy, France

The Creully wastewater treatment plant is located in Creully sur Seulles, a commune in the Calvados department of Normandy, France. The plant serves a population of approximately 2,651 and operates with advanced treatment processes, ensuring high-quality effluent before discharge. With a designed capacity of 4,000 cubic meters per day and an average discharge volume of 472.93 cubic meters per day, the plant operates well within its capacity. As a facility in France, it adheres to the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and agglomerations of this scale. The plant is situated within 10 kilometers of the coast, discharging treated wastewater into the local watershed that ultimately reaches the English Channel. This proximity to marine environments underscores the importance of its advanced treatment in protecting coastal water quality and ecosystems.

The plant discharges into the Seulles River, which flows through the Normandy countryside before emptying into the English Channel near Courseulles-sur-Mer. The downstream environment supports diverse aquatic life and is part of a coastal zone that includes important migratory corridors for fish and bird species. The advanced treatment helps minimize nutrient loading and protects the sensitive marine ecosystem from eutrophication.
