Overview
VERSON wastewater treatment plant serves Éterville, Normandy, France, with a designed capacity of 1.00 and a population equivalent of 18,811. It operates under the EU Urban Waste Water Treatment Directive.
VERSON wastewater treatment plant is located in Éterville, near Caen in the Normandy region of France. The facility serves a population equivalent of 18,811 and has a designed capacity of 1.00, placing it in the medium agglomeration category under EU regulations. As a French plant, VERSON operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas, which is common in regions with significant ecological value. The treated effluent from VERSON is discharged into the local watershed, which ultimately drains into the English Channel via the Orne River and its estuary. The downstream environment supports diverse aquatic life and is an important ecological corridor for migratory species.
Environmental context
The VERSON plant discharges into the Orne River basin, which flows northward through Caen and into the English Channel at the Baie de Seine. This coastal zone supports rich marine biodiversity and is a key area for migratory fish such as salmon and sea trout. The watershed also includes agricultural and urban runoff, making effective wastewater treatment critical for maintaining water quality in the estuary and coastal waters.
