Overview
Divonne-les-Bains wastewater treatment plant serves 20,100 people in Auvergne-Rhône-Alpes, France. It operates under the EU Urban Waste Water Treatment Directive, ensuring compliance with secondary treatment standards for agglomerations of this size.
The Divonne-les-Bains wastewater treatment plant is located in the commune of Divonne-les-Bains, within the Ain department of the Auvergne-Rhône-Alpes region in eastern France. The facility serves a population of approximately 20,100 residents, classifying it as a medium-sized agglomeration under French and European regulations. As a plant in France, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations with a population equivalent between 10,000 and 150,000. Compliance with the directive ensures that treated effluent meets quality standards before discharge. The plant's treated wastewater is discharged into the local watershed, which ultimately drains into the Rhône River basin and then into the Mediterranean Sea. The surrounding environment includes the Jura foothills and Lake Geneva region, supporting diverse aquatic life and recreational water use. Proper treatment helps protect downstream ecosystems and water quality in this sensitive alpine area.
Environmental context
The plant discharges into the local water system that flows into the Rhône River, one of Europe's major rivers, which empties into the Mediterranean Sea. The region is ecologically sensitive due to its proximity to Lake Geneva and the Jura Mountains, supporting diverse aquatic habitats and migratory fish species. Effective wastewater treatment is crucial to prevent nutrient enrichment and protect downstream water quality in this internationally important watershed.
