ALBIEZ MONTROND Wastewater Treatment Plant, Albiez-Montrond, France

ALBIEZ MONTROND is a municipal wastewater treatment plant located in Albiez-Montrond, a commune in the Savoie department of the Auvergne-Rhône-Alpes region, France. The plant serves a population of approximately 2,091 and is situated in the Maurienne valley, a mountainous area in the French Alps. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a design capacity of 5,000 m³/day and a current discharge volume of 373.03 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Arc River, a tributary of the Isère River, and then into the Rhône River before reaching the Mediterranean Sea. The plant plays a key role in protecting the sensitive alpine aquatic environment and downstream water quality.

The plant discharges into the Arc River basin, which flows through the Maurienne valley and joins the Isère River near Albertville. The Isère then flows into the Rhône, one of Europe's major rivers, which empties into the Mediterranean Sea. The alpine watershed supports diverse aquatic life, including fish species such as brown trout, and is ecologically sensitive due to its mountainous terrain and seasonal flow variations.
