Overview
Chambery wastewater treatment plant serves approximately 185,000 people in La Balme, Auvergne-Rhône-Alpes, France. The facility operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this
The Chambery wastewater treatment plant is located in La Balme, near Chambéry, in the Savoie department of the Auvergne-Rhône-Alpes region, France. It serves a population of approximately 184,754, classifying it as a large agglomeration under EU regulations. The plant is situated inland, away from the coast, and its operations are part of the regional water management infrastructure. As a large agglomeration in France, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary biological treatment as a minimum, and tertiary treatment if the receiving waters are sensitive. The directive also mandates compliance with discharge standards for biochemical oxygen demand, chemical oxygen demand, and suspended solids. The plant's treatment processes are designed to meet these regulatory requirements, ensuring effective pollutant removal before discharge. The treated effluent from the Chambery plant is discharged into the local watershed, which ultimately drains into the Rhône River basin. The Rhône flows southward into the Mediterranean Sea, supporting diverse aquatic ecosystems along its course. The plant plays a crucial role in protecting the water quality of the Rhône and its tributaries, as well as the downstream marine environment, by reducing nutrient and pollutant loads.
Environmental context
The Chambery plant discharges into the Rhône River basin, which flows into the Mediterranean Sea. The Rhône is a major European river supporting diverse aquatic life and providing water for agriculture, industry, and drinking water. The plant's treatment helps protect the river's ecological health and the sensitive coastal ecosystems of the Camargue delta and the Gulf of Lion.
