Overview
ARS EN RE wastewater treatment plant serves Ars-en-Ré, Nouvelle-Aquitaine, France. It is located on the Île de Ré and serves a population of 14,764.
The ARS EN RE wastewater treatment plant is located in Ars-en-Ré, a commune on the Île de Ré in the Nouvelle-Aquitaine region of France. The plant serves a population of approximately 14,764 residents and visitors, particularly during the tourist season. As part of France's wastewater infrastructure, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Under the EU UWWTD, plants serving between 10,000 and 150,000 population equivalents must achieve secondary treatment standards, with tertiary treatment required if discharging into sensitive areas. The Île de Ré's coastal environment likely classifies the receiving waters as sensitive, necessitating advanced treatment to protect marine ecosystems. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating it can handle peak loads. The plant discharges treated wastewater into the Atlantic Ocean via the Pertuis d'Antioche strait, which surrounds the Île de Ré. This coastal area supports diverse marine life, including seagrass beds and fish nurseries. Proper treatment is critical to prevent nutrient enrichment and protect the island's tourism-dependent economy and fragile coastal ecology.
Environmental context
The ARS EN RE plant discharges into the Atlantic Ocean near the Île de Ré, part of the Pertuis d'Antioche. This coastal zone supports diverse marine habitats, including seagrass meadows and migratory bird populations. Nutrient-sensitive waters require advanced treatment to prevent eutrophication and protect the region's ecological balance.
