LE FRESNE SUR LOIRE La Fresnaye is an advanced wastewater treatment plant located in Le Fresnay, within the commune of Ingrandes-le-Fresne-sur-Loire in the Pays de la Loire region of France. The plant serves a population of 2,350 and has a designed capacity of 2,700 cubic meters per day, with a current discharge volume of 419.24 cubic meters per day. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment typically includes nutrient removal to protect sensitive water bodies, aligning with French regulations for areas designated as sensitive to eutrophication. The treated effluent is discharged into the Loire River, one of France's major waterways, which flows westward through the Loire Valley to the Atlantic Ocean. The plant plays a key role in protecting the Loire's water quality, supporting aquatic life and downstream ecosystems, including the Loire estuary and its associated wetlands.
Environmental context
The plant discharges into the Loire River, which flows through the Loire Valley to the Atlantic Ocean. The Loire is a major river supporting diverse aquatic habitats and migratory fish species. The advanced treatment helps reduce nutrient loads, protecting downstream waters from eutrophication and maintaining ecological balance in the river and its estuary.
