Overview
The Notre Dame du Cruet SIEPAB wastewater treatment plant serves Saint-Étienne-de-Cuines in the Savoie department of Auvergne-Rhône-Alpes, France. It treats wastewater from a population of approximately 12,374.
The Notre Dame du Cruet SIEPAB wastewater treatment plant is located in Saint-Étienne-de-Cuines, within the Maurienne valley in the French Alps. It serves a population of around 12,374 people, making it a medium-sized agglomeration under French regulations. The plant is situated near the Autoroute de la Maurienne, a major transport corridor in the region. As a French wastewater facility, the plant operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are sensitive to eutrophication. It is expected to meet the regulatory standards for its population equivalent. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Arc River, a tributary of the Isère River. The Isère flows into the Rhône River, which empties into the Mediterranean Sea. The Maurienne valley is an ecologically sensitive alpine region, and the plant plays a key role in protecting downstream water quality and aquatic habitats.
Environmental context
The plant discharges into the Arc River, which flows through the Maurienne valley before joining the Isère River. The Isère is a major tributary of the Rhône, one of Europe's most important rivers, which drains into the Mediterranean Sea. The alpine watershed supports diverse aquatic life, including fish species such as brown trout and grayling. The plant's operations help maintain water quality in this ecologically sensitive region, which is also important for tourism and agriculture.

The treated effluent is discharged into the local watershed, which flows into the Arc River. The Arc River is a tributary of the Isère River, which eventually reaches the Rhône River and the Mediterranean Sea.
As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary treatment for agglomerations of this size and may require more stringent treatment if the receiving waters are sensitive.
Under the EU Urban Waste Water Treatment Directive, plants serving between 10,000 and 150,000 population equivalents are required to have secondary treatment (biological treatment) as a minimum. In sensitive areas, tertiary treatment for nutrient removal may also be required.
