ORAISON 2 is a municipal wastewater treatment plant located in Oraison, within the Alpes-de-Haute-Provence department of the Provence-Alpes-Côte d'Azur region in southeastern France. The plant serves a population equivalent of approximately 9,330, placing it in the small to medium agglomeration category under European Union classification. As a French wastewater facility, ORAISON 2 operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into freshwater. The plant's treatment processes are designed to meet national standards set by the French Ministry of Ecology, with oversight from the local water agency (Agence de l'Eau). The treated effluent from ORAISON 2 is discharged into the local watershed, which ultimately drains into the Durance River, a major tributary of the Rhone River. The Durance River supports diverse aquatic life and is an important water resource for irrigation and hydroelectric power in the region. The plant plays a key role in protecting the water quality of this river system.
Environmental context
ORAISON 2 discharges into the Durance River basin, which flows into the Rhone River and eventually the Mediterranean Sea. The Durance is a dynamic alpine river that supports diverse aquatic ecosystems, including fish species such as the endemic Rhone streber. The plant's operations help maintain water quality in this ecologically sensitive river system, which is also used for agriculture and recreation.
