LEVENS La Gumba Wastewater Treatment Plant, Levens, France

LEVENS La Gumba is a municipal wastewater treatment plant located in Levens, a commune in the Alpes-Maritimes department of the Provence-Alpes-Côte d'Azur region in southeastern France. The plant serves a population of approximately 2,929 and has a designed capacity of 3,000 cubic meters per day, with an average discharge volume of 522.53 m³/day. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with EU effluent standards before discharge. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea via the Var River or its tributaries. The region's coastal and riverine ecosystems benefit from the plant's treatment, as it helps protect water quality in an area known for its biodiversity and tourism.

The plant discharges into the Var River basin, which flows into the Mediterranean Sea near Nice. The downstream environment includes coastal habitats and marine ecosystems that are sensitive to nutrient pollution. Secondary treatment reduces organic load and suspended solids, helping to maintain water quality in the Var River and the adjacent Ligurian Sea, which supports diverse aquatic life and recreational activities.
