Overview
JOYEUSE wastewater treatment plant in Joyeuse, Auvergne-Rhône-Alpes, France, serves 1,800 people with advanced treatment. It discharges 321.12 m³/day and has a designed capacity of 3,150 m³/day.
The JOYEUSE wastewater treatment plant is located in the commune of Joyeuse, in the Ardèche department of Auvergne-Rhône-Alpes, France. It serves a population of 1,800 and operates with advanced treatment processes, ensuring high-quality effluent. The plant has a designed capacity of 3,150 m³/day and currently treats an average daily volume of 321.12 m³. As a French facility, JOYEUSE operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum for agglomerations of this size. The advanced treatment level indicates that the plant likely employs additional nutrient removal or disinfection steps to meet stringent environmental standards, particularly if the receiving water body is sensitive. The treated effluent is discharged into the local watershed, which ultimately drains into the Ardèche River and then the Rhône River before reaching the Mediterranean Sea. The plant plays a key role in protecting the water quality of these downstream water bodies, supporting aquatic ecosystems and recreational uses.
Environmental context
The JOYEUSE plant discharges into the Ardèche River basin, a tributary of the Rhône River, which flows into the Mediterranean Sea. The Ardèche River supports diverse aquatic life and is an important corridor for migratory fish. The advanced treatment helps minimize nutrient loading and protects the ecological health of the river and the downstream Rhône delta.
