Overview
Villers-Cotterêts wastewater treatment plant serves approximately 13,600 residents in Hauts-de-France, France. The facility operates under the EU Urban Waste Water Treatment Directive, ensuring compliance with secondary treatment standards for medium
The Villers-Cotterêts wastewater treatment plant is located in the commune of Villers-Cotterêts in the Aisne department of Hauts-de-France, France. Serving a population of about 13,600, it is classified as a medium-sized agglomeration under French and EU regulations. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving between 10,000 and 150,000 population equivalents are required to provide secondary treatment, with tertiary treatment mandated in sensitive areas. It is expected to meet these regulatory standards. The treated effluent is discharged into local watercourses that eventually drain into the Seine River basin, flowing northward to the English Channel. The plant plays a key role in protecting the region's water quality and supporting the ecological health of downstream aquatic habitats.
Environmental context
The plant discharges into the local watershed, which is part of the Seine River basin. The Seine flows through Paris and into the English Channel, supporting diverse aquatic life and serving as a critical water resource. The Hauts-de-France region features a mix of agricultural and urban areas, and the plant helps mitigate nutrient pollution and protect downstream ecosystems.
Frequently asked questions
The plant is located at 60 Rue du Sergent Joe Pino, in the Pisseleux area of Villers-Cotterêts, in the Aisne department of Hauts-de-France, France.
The plant serves approximately 13,592 people, classifying it as a medium-sized agglomeration under EU regulations.
The treated effluent is discharged into local watercourses that are part of the Seine River basin, eventually flowing into the English Channel.
As a plant serving over 10,000 population equivalents, it is required to provide at least secondary treatment under the EU UWWTD. In sensitive areas, tertiary treatment may be mandated to reduce nutrient pollution.
In France, plants of this scale typically employ secondary biological treatment processes such as activated sludge or biofiltration, with possible tertiary steps like phosphorus removal if discharging into sensitive water bodies.
