LA CLAYETTE Wastewater Treatment Plant, La Chapelle-sous-Dun, France

LA CLAYETTE is a wastewater treatment plant located in La Chapelle-sous-Dun, within the Bourgogne-Franche-Comté region of France. The facility serves a population of approximately 3,085 and operates under the French regulatory framework, which implements the EU Urban Waste Water Treatment Directive (91/271/EEC). As a small agglomeration, it is required to provide appropriate treatment to protect receiving waters. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 21,000 m³/day and an actual discharge volume of 550.36 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treatment level meets the stringent standards set by French and European regulations for sensitive areas. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River basin and then into the Atlantic Ocean. The plant plays a vital role in protecting the region's water quality, supporting aquatic life, and maintaining the ecological balance of downstream environments. Its advanced treatment helps reduce nutrient loads and other pollutants, contributing to the health of the Loire River system.

The plant discharges into the local watershed, part of the Loire River basin, which flows into the Atlantic Ocean. The Loire basin is ecologically significant, supporting diverse aquatic species and providing important habitats. Advanced treatment at this plant helps minimize nutrient pollution, protecting downstream water quality and the sensitive ecosystems of the Loire estuary.
