PLOEREN Les deux moulins Wastewater Treatment Plant, Plougoumelen, Bretagne

PLOEREN Les deux moulins is a wastewater treatment plant located in Plougoumelen, near Vannes in the Morbihan department of Bretagne, France. It serves a population of approximately 5,717 people, classifying it as a small to medium agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated near the Voie Express de Nantes à Brest, in the Les Deux Moulins area. As a French facility, the plant is subject to national regulations implementing the EU UWWTD, which requires secondary treatment for agglomerations of this size. The designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating a modest scale. Typical French plants of this size employ biological treatment to meet effluent standards. The plant discharges into the local watershed, which ultimately drains into the Gulf of Morbihan, a semi-enclosed marine inlet of the Atlantic Ocean. The Gulf of Morbihan is an ecologically sensitive area known for its rich biodiversity, including seagrass beds and migratory bird populations. The plant's operations help protect this coastal environment from nutrient pollution and other contaminants.

The plant's treated effluent flows into the local water system, which drains into the Gulf of Morbihan, a coastal inlet connected to the Atlantic Ocean. The Gulf of Morbihan is a shallow, semi-enclosed basin with high ecological value, supporting diverse marine life, including seagrass meadows and shellfish beds. Nutrient loading from wastewater can contribute to eutrophication, making effective treatment crucial for preserving water quality and aquatic habitats in this sensitive coastal zone.
