VENDRES Bourg et ZAC Via Europa Wastewater Treatment Plant, Vendres, Occitanie

The VENDRES Bourg et ZAC Via Europa wastewater treatment plant is located in Vendres, a commune in the Hérault department of Occitanie, southern France. It serves a population of approximately 2,100 and has a designed capacity of 5,000 cubic meters per day, with a current discharge volume of 374.64 m³/day. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. As a facility in France, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on the sensitivity of receiving waters. For a plant serving around 2,100 people, secondary treatment is typically required, but the advanced treatment here indicates a higher level of nutrient removal or disinfection, likely due to the sensitivity of the local environment. The plant is situated less than 10 km from the Mediterranean coast, and its treated effluent likely discharges into a coastal water body or a river that flows into the Mediterranean. This proximity to the sea means that the plant's discharge can affect coastal water quality, marine ecosystems, and bathing waters. The advanced treatment helps minimize nutrient loading and protect the sensitive coastal environment.

The plant is located near the Mediterranean coast in the Occitanie region, within the watershed of the Aude River or smaller coastal streams that drain into the Golfe du Lion. The receiving water body is likely a coastal lagoon or the Mediterranean Sea itself. This area supports diverse marine life, including seagrass meadows and fish nurseries, and is important for tourism and recreation. Advanced treatment reduces the risk of eutrophication and protects these sensitive coastal ecosystems.
