Locquirec le Bouillen Wastewater Treatment Plant | Locquirec, Bretagne

Locquirec le Bouillen is an advanced wastewater treatment plant located in the Zone Artisanale du Boulien in Locquirec, a commune in the Finistère department of Bretagne, France. The plant serves a population of approximately 2,033 residents and is part of the region's municipal wastewater infrastructure. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). With a designed capacity of 4,500 m³/day and an actual discharge volume of 362.68 m³/day, the plant operates well within its capacity, ensuring reliable treatment for the local community. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the English Channel. The receiving water bodies support diverse aquatic life and are important for regional biodiversity. The advanced treatment helps protect downstream ecosystems from nutrient pollution and other contaminants.

The plant discharges into the local watershed of the Douron River, which flows into the English Channel near the coast of Locquirec. This coastal area supports diverse marine life and is part of a sensitive ecological zone. The advanced treatment process helps minimize nutrient loading and protects the downstream estuarine and marine environments from eutrophication.
