Overview
The ANSE wastewater treatment plant serves the commune of Anse in Auvergne-Rhône-Alpes, France. It handles wastewater from approximately 18,300 residents as part of the region's municipal infrastructure.
The ANSE wastewater treatment plant is located in Anse, a commune in the Rhône department of the Auvergne-Rhône-Alpes region in eastern France. The plant serves a population of around 18,300 people, placing it in the medium agglomeration category under French and EU regulations. As a French facility, the plant 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. The regulatory framework ensures appropriate standards are met. The treated effluent from the plant is discharged into the local water system, which ultimately drains into the Saône River. The Saône flows southward to join the Rhône River near Lyon, and the Rhône continues to the Mediterranean Sea. This river system supports diverse aquatic life and is an important ecological corridor in the region.
Environmental context
The ANSE plant discharges into the Saône River basin, which flows into the Rhône River and then to the Mediterranean Sea. The Saône and Rhône rivers support diverse aquatic ecosystems, including fish species such as the European eel and various migratory fish. The watershed is also important for regional agriculture and urban water supply, making effective wastewater treatment critical for maintaining water quality and ecological health.
