The Lavilledieu Coudoulas wastewater treatment plant is located in Lavilledieu, a commune in the Ardèche department of the Auvergne-Rhône-Alpes region, France. The plant serves a population of approximately 1,260 residents and operates with a designed capacity of 3,000 cubic meters per day, with an average discharge volume of 224.78 m³/day. As a secondary treatment facility, the plant meets the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The plant's treatment process reduces organic matter and suspended solids before discharge, ensuring compliance with French national standards derived from the directive. The treated effluent is discharged into the local watershed, which ultimately drains into the Ardèche River and then the Rhône River, a major European waterway flowing into the Mediterranean Sea. The plant plays a key role in protecting the water quality of these downstream water bodies and supporting the ecological health of the region.
