PLOUBALAY Les Saudray Wastewater Treatment Plant, Lancieux, Bretagne

PLOUBALAY Les Saudray is a wastewater treatment plant located in Lancieux, in the Bretagne region of France. It serves a population of approximately 6,430 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated near the coast, within 50 km of the sea, which influences its environmental considerations. Under the EU UWWTD, agglomerations of this size are generally required to provide secondary treatment or equivalent. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar units), indicating a modest scale. As a French facility, it operates under national regulations that transpose the UWWTD, with oversight from local water agencies. The treated effluent from the plant discharges into the local watershed, which ultimately drains into the English Channel. The coastal environment supports diverse marine life and is important for regional biodiversity. The plant plays a key role in protecting the quality of nearby coastal waters and the ecosystems they sustain.

The plant's receiving water body is part of the local watershed that flows into the English Channel near the coast of Bretagne. This coastal zone supports diverse aquatic life, including fish and invertebrate species, and is an important area for migratory birds. The proximity to the sea means that nutrient and pollutant loads from wastewater must be carefully managed to prevent eutrophication and maintain water quality in the marine environment.
