ALLEINS NOUVELLE is a municipal wastewater treatment plant located in Alleins, a commune in the Bouches-du-Rhône department of the Provence-Alpes-Côte d'Azur region in southern France. The plant serves a population of around 1,996 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant provides secondary treatment, which is the minimum standard required by the EU UWWTD for freshwater discharges from agglomerations of this size. With a designed capacity of 2,500 cubic meters per day and an average daily discharge volume of 356 cubic meters, the plant operates well within its capacity, ensuring effective treatment of local wastewater. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea via the Durance River and the Rhône River. This discharge supports the ecological health of downstream water bodies, including the Camargue delta, a region of high ecological importance for migratory birds and aquatic life.
Environmental context
The plant discharges into the local watershed, which flows into the Durance River, a major tributary of the Rhône River. The Rhône then empties into the Mediterranean Sea near the Camargue delta. This region supports diverse aquatic life and serves as an important migratory corridor for birds. The secondary treatment provided by the plant helps reduce nutrient and organic pollution, protecting downstream ecosystems from eutrophication and other impacts.
