Ploneour Lanvern Keriforn Wastewater Treatment Plant, Plonéour-Lanvern, Bretagne

Ploneour Lanvern Keriforn is an advanced wastewater treatment plant located in Keriforn Vihan, Plonéour-Lanvern, in the Finistère department of Bretagne, France. The facility serves a population of approximately 4,600 and is designed to handle a capacity of 9,900 m³ per day, with an average daily discharge of 820.63 m³. The plant employs advanced treatment processes, meeting stringent standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). As a facility serving a small agglomeration (under 10,000 people), it is required to provide appropriate treatment to protect the receiving environment. The plant's advanced treatment level indicates it likely includes nutrient removal to safeguard sensitive water bodies. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Baie d'Audierne. The region's coastal and estuarine ecosystems are ecologically sensitive, supporting diverse marine life and migratory bird populations. The plant's advanced treatment helps minimize nutrient loading and protect water quality in this important coastal area.

The plant discharges into the local watershed that flows into the Baie d'Audierne, a coastal bay on the Atlantic Ocean in Bretagne. This area supports diverse aquatic life, including fish, shellfish, and migratory birds. The advanced treatment reduces nutrient pollution, protecting the bay's ecological balance and recreational uses.
