Overview
Gournay-en-Bray wastewater treatment plant serves approximately 10,200 people in Normandy, France. The facility operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The Gournay-en-Bray wastewater treatment plant is located in the commune of Gournay-en-Bray, within the Seine-Maritime department of the Normandy region in northern France. The facility serves a population of approximately 10,200 residents, classifying it as a medium-sized agglomeration under European Union regulations. As a French wastewater treatment plant, Gournay-en-Bray operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent between 2,000 and 15,000. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The plant's treated effluent is discharged into the local water system, which ultimately drains into the Seine River basin. The Seine River flows through Paris and into the English Channel, supporting diverse aquatic ecosystems and serving as a critical water resource for the region. The plant plays a key role in protecting downstream water quality and the ecological health of the Seine estuary.
Environmental context
The Gournay-en-Bray plant discharges into the local watershed, which is part of the Seine River basin. The Seine flows northwest through Normandy and into the English Channel, supporting migratory fish species and estuarine habitats. The plant's treatment helps reduce nutrient loads that could contribute to eutrophication in the Seine estuary and coastal waters.
