Avranches _ Le Val Saint Pere Wastewater Treatment Plant, Normandy, France

The Avranches _ Le Val Saint Pere wastewater treatment plant is situated in Marcey-les-Grèves, near Avranches in the Normandy region of France. It serves a population equivalent of 36,370, classifying it as a medium-sized agglomeration under EU standards. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), and it is located within 50 km of the coast, indicating potential sensitivity to nutrient discharge. The plant's treated effluent likely discharges into local watercourses that flow into the Baie du Mont-Saint-Michel, a significant ecological area. The bay supports diverse marine life and is an important migratory corridor for birds. The plant's performance is critical to protecting this downstream environment.

The plant is located near the Baie du Mont-Saint-Michel, a major tidal bay on the English Channel. The bay is ecologically sensitive, supporting diverse aquatic life and serving as a key stopover for migratory birds. Treated wastewater from the plant flows into local rivers that drain into the bay, making nutrient management important to prevent eutrophication.
