Overview
CHAMP SUR LAYON BORDURE DU CD 199 is a secondary wastewater treatment plant in Bellevigne-en-Layon, Pays de la Loire, France, serving 2,150 people with a designed capacity of 1,800 m³/day.
CHAMP SUR LAYON BORDURE DU CD 199 is a wastewater treatment plant located in Bellevigne-en-Layon, within the Maine-et-Loire department of Pays de la Loire, France. The plant serves a population of 2,150 and is designed to handle a capacity of 1,800 cubic meters per day, with an average discharge volume of 383.56 m³/day. It provides secondary treatment, which is the standard biological treatment stage required for most municipal wastewater in France. As a plant in the European Union, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which mandates secondary treatment for agglomerations with a population equivalent above 2,000. For its scale, secondary treatment is appropriate, and the plant's discharge must meet the directive's quality standards for biochemical oxygen demand, chemical oxygen demand, and suspended solids. The plant's performance is likely monitored by the local water agency (Agence de l'Eau Loire-Bretagne) to ensure compliance. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Layon River, a tributary of the Loire River. The Loire is one of France's major rivers, flowing into the Atlantic Ocean. The plant plays a role in protecting the water quality of the Layon and Loire rivers, which support diverse aquatic ecosystems and are important for regional biodiversity.
Environmental context
The plant discharges into the Layon River basin, which flows into the Loire River, one of the last wild rivers in Europe. The Loire estuary and its floodplains support a rich variety of fish, birds, and plant species, including migratory fish like Atlantic salmon and European eel. The plant's secondary treatment helps reduce organic pollution and nutrient loads, contributing to the ecological health of this sensitive river system.
