QUIBERON Pont er Bail Wastewater Treatment Plant, Quiberon, Brittany

QUIBERON Pont er Bail is a municipal wastewater treatment plant located in Quiberon, a coastal town in the Brittany region of northwestern France. The plant serves a population of around 33,712, placing it in the medium agglomeration category under French regulations. Its location near the Atlantic coast makes it subject to stringent discharge standards to protect marine environments. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into coastal waters. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a moderate scale of operations. The treated effluent from QUIBERON Pont er Bail ultimately reaches the Atlantic Ocean via local coastal waters. The surrounding region, part of the Morbihan department, features a rugged coastline and supports diverse marine life, including seabirds and fish species. Proper treatment is essential to prevent nutrient pollution and protect the ecological health of the Bay of Biscay.

The plant discharges into the Atlantic Ocean near the Quiberon Peninsula, a coastal area known for its rich marine biodiversity. The receiving waters are part of the Bay of Biscay, which supports important fisheries and migratory bird populations. Effective wastewater treatment is critical to prevent eutrophication and maintain water quality in this ecologically sensitive coastal zone.
