Overview
CHAMAGNIEU _ MARSA is an advanced wastewater treatment plant in Chamagnieu, Auvergne-Rhône-Alpes, France, serving 2,600 people with a discharge volume of 463.84 m³/day.
CHAMAGNIEU _ MARSA is an advanced wastewater treatment plant located in Chamagnieu, a commune in the Isère department of the Auvergne-Rhône-Alpes region, France. The plant serves a population of 2,600 and has a designed capacity of 5,600 m³/day, with an actual discharge volume of 463.84 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a French facility, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas. For a population of 2,600, the directive mandates at least secondary treatment, but the plant's advanced level indicates it likely discharges into a sensitive catchment. The treated effluent is discharged into the local watershed, which ultimately drains into the Rhône River basin. The Rhône is one of Europe's major rivers, flowing into the Mediterranean Sea. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the Rhône corridor, which is ecologically significant for fish migration and biodiversity.
Environmental context
The plant discharges into the Rhône River basin, which flows southward through southeastern France and into the Mediterranean Sea. The Rhône is a major European river supporting diverse aquatic life and migratory fish species. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality in the Rhône delta and coastal Mediterranean environment.
