YAINVILLE Wastewater Treatment Plant, Yainville, Normandy, France

YAINVILLE is a wastewater treatment plant located in Yainville, a commune in the Seine-Maritime department of Normandy, France. The facility serves a population of approximately 1,150 and operates with advanced treatment processes, reflecting France's commitment to high environmental standards under the EU Urban Waste Water Treatment Directive. The plant has a designed capacity of 2,500 m³/day and currently discharges 205.16 m³/day of treated wastewater. Advanced treatment ensures removal of nutrients and other pollutants, meeting stringent requirements for sensitive areas. The plant's scale corresponds to a small agglomeration, for which the EU directive mandates appropriate treatment levels. The treated effluent is discharged into the local watershed, which ultimately drains into the Seine River and then the English Channel. This contributes to the protection of downstream aquatic ecosystems and the marine environment. The plant plays a key role in maintaining water quality in the Normandy region.

The YAINVILLE plant discharges into the Seine River basin, which flows through Normandy and into the English Channel. The Seine estuary and downstream marine areas support diverse aquatic life, including migratory fish species. Advanced treatment at this plant helps reduce nutrient loading, protecting the sensitive coastal and marine ecosystems from eutrophication.
