MER Wastewater Treatment Plant, Courbouzon, Centre-Val de Loire, France

The MER wastewater treatment plant is located in Courbouzon, within the Centre-Val de Loire region of France. It serves a population equivalent of approximately 8,816 people, classifying it as a small to medium agglomeration under EU regulations. The plant is situated near the Loire River, a major watercourse that flows through central France. As a French wastewater facility, MER operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 2,000 and 10,000 population equivalent discharging into freshwaters. The regulatory framework ensures appropriate treatment standards are met. The treated effluent from MER likely discharges into the Loire River or its tributaries, which flow westward through the Loire Valley and eventually into the Bay of Biscay. The Loire River supports diverse aquatic life and is an important ecological corridor for migratory fish species. The plant plays a key role in protecting water quality in this sensitive river basin.

The MER plant discharges into the Loire River basin, which drains into the Bay of Biscay on the Atlantic coast. The Loire is one of France's longest rivers, supporting a rich ecosystem including migratory fish such as Atlantic salmon and European eel. The river's watershed includes agricultural and urban areas, making wastewater treatment crucial for maintaining water quality and biodiversity.
