Barjouville Wastewater Treatment Plant - Centre-Val de Loire, France

The Barjouville wastewater treatment plant is located in Barjouville, a commune in the Eure-et-Loir department of the Centre-Val de Loire region, France. It serves a population of 2,869 and operates as a secondary treatment facility, managing municipal wastewater from the local community. As a secondary treatment plant, Barjouville meets the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary biological treatment for agglomerations of this size. The plant has a designed capacity of 2,200 m³/day and currently discharges an average volume of 511.82 m³/day, indicating operational headroom. The treated effluent is discharged into a local watercourse that flows into the Eure River, a tributary of the Seine. The Seine basin supports diverse aquatic life and is an important ecological corridor in northern France. The plant's operations help protect downstream water quality in the Seine estuary and the English Channel.

The plant discharges into a local stream that feeds the Eure River, which flows into the Seine River and ultimately reaches the English Channel. The Seine basin is a densely populated and agriculturally intensive region, making nutrient removal from wastewater critical to prevent eutrophication in coastal waters. The plant's secondary treatment reduces organic load and suspended solids, supporting the ecological health of the downstream river system.
