The Fontaines sur Saone wastewater treatment plant is located in Fontaines-sur-Saône, a commune in the Auvergne-Rhône-Alpes region of France. Serving a population of approximately 42,163, the plant is part of the municipal infrastructure managed by the Métropole de Lyon. As a medium-sized agglomeration, it plays a key role in protecting local water quality.

It is expected to meet these regulatory standards. The directive ensures that wastewater is adequately treated before discharge to prevent environmental harm. The plant discharges into the Saône River, a major tributary of the Rhône. The Saône flows southward through Lyon, where it joins the Rhône, which then continues to the Mediterranean Sea. This river system supports diverse aquatic life and is an important ecological corridor in the region. Effective treatment at Fontaines sur Saone helps maintain water quality in the Saône and downstream environments.
