AURAY Lann Pont Houar Wastewater Treatment Plant, Crac'h, Brittany

AURAY Lann Pont Houar is a wastewater treatment plant located in Crac'h, a commune in the Morbihan department of Brittany, France. The plant serves a population of approximately 32,400, classifying it as a medium agglomeration under EU regulations. Its location near the southern coast of Brittany places it in a region with significant environmental sensitivity. 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. The plant's compliance with EU standards ensures appropriate treatment before discharge. The plant's proximity to the coast (within 50 km) means its treated effluent likely drains into the Atlantic Ocean via local rivers or direct discharge. The surrounding watershed supports diverse aquatic life and contributes to the ecological health of the Gulf of Morbihan and the Bay of Biscay. Proper treatment is essential to protect these marine environments from nutrient pollution and other contaminants.

The plant is located in the Morbihan department of Brittany, a region characterized by a rugged coastline and numerous estuaries. Treated wastewater likely discharges into the Gulf of Morbihan, a semi-enclosed sea that connects to the Atlantic Ocean. This area supports diverse marine habitats, including seagrass beds and shellfish beds, which are sensitive to nutrient loading. The plant's operation under EU directives helps mitigate impacts on this ecologically important coastal zone.
