CONDE SUR NOIREAU Wastewater Treatment Plant, Condé-en-Normandie, Normandy

CONDE SUR NOIREAU is an advanced wastewater treatment plant located in Condé-en-Normandie, in the Normandy region of France. The facility serves a population of 5,563 and has a designed capacity of 9,600 cubic meters per day, with an average discharge volume of 992.43 cubic meters per day. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (5,000-10,000 population equivalent), the directive requires secondary treatment, but France often mandates advanced treatment in sensitive areas to protect water quality. The plant discharges treated effluent into local waterways that ultimately drain into the English Channel. Its advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the region's rivers and coastal waters.

The plant discharges into the Noireau River, a tributary of the Orne River, which flows into the English Channel at Ouistreham. The watershed supports diverse freshwater and estuarine habitats, including fish spawning grounds and migratory corridors for species such as Atlantic salmon. Advanced treatment reduces nutrient loading, helping to prevent eutrophication in the coastal zone.
