UGINE Wastewater Treatment Plant, Ugine, Auvergne-Rhône-Alpes, France

The UGINE wastewater treatment plant is located in Ugine, a commune in the Savoie department of the Auvergne-Rhône-Alpes region in southeastern France. The facility serves a population of around 10,676 residents, placing it in the medium agglomeration category under EU regulations. As a French treatment plant, UGINE 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 advanced treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The plant discharges treated effluent into the local watershed, which ultimately drains into the Isère River and then the Rhône River, one of Europe's major waterways. The Rhône flows into the Mediterranean Sea, making the plant's operations important for protecting downstream aquatic ecosystems and coastal water quality.

The UGINE plant discharges into the local water system that feeds the Isère River, a major tributary of the Rhône River. The Rhône flows through southeastern France into the Mediterranean Sea, supporting diverse aquatic life and important migratory fish species. The watershed includes alpine and pre-alpine environments, where water quality is critical for both ecological health and human uses such as recreation and drinking water supply.
