SAINT LO Wastewater Treatment Plant, Saint-Lô, Normandie, France

The SAINT LO wastewater treatment plant is located in Saint-Lô, a commune in the Manche department of Normandie, France. The plant serves a population equivalent of 38,500, classifying it as a medium agglomeration under EU regulations. Its location along the Promenade des Ports places it near the Vire River, which flows into the English Channel. As a French wastewater facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a moderate scale of operations. The treated effluent is discharged into the Vire River, which flows northward through the Normandy countryside before reaching the Baie des Veys and ultimately the English Channel. This watershed supports diverse aquatic life and is an important ecological corridor for migratory fish species. The plant's performance is critical to maintaining water quality in this coastal region.

The SAINT LO plant discharges into the Vire River, which flows through the Normandy region and empties into the Baie des Veys, a large estuary on the English Channel. This coastal watershed supports diverse aquatic habitats, including salt marshes and mudflats that are vital for migratory birds and fish. The plant's operations help protect downstream water quality in this ecologically sensitive area.
