Chorges chef lieu is a municipal wastewater treatment plant located in the commune of Chorges, in the Hautes-Alpes department of the Provence-Alpes-Côte d'Azur region, France. The plant serves a population of about 2,650 residents and is situated in the alpine foothills near the Durance River valley. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. Its designed capacity of 2,800 m³/day indicates it is sized to handle peak flows from the local community, with an average daily discharge of 472.76 m³/day. The treated effluent is discharged into the local watershed, which ultimately drains into the Durance River, a major tributary of the Rhône. The Durance supports diverse aquatic life and is an important water source for irrigation and hydroelectric power in the region. The plant's operation helps protect downstream water quality in this ecologically sensitive alpine river system.
Environmental context
The plant discharges into the Durance River basin, which flows southwest to join the Rhône River near Avignon. The Durance is a dynamic alpine river that supports a variety of fish species, including the endangered European eel, and provides critical habitat for migratory birds. The watershed is also used for agriculture and recreation, making effective wastewater treatment essential for maintaining water quality and ecosystem health.
