Overview
Villers-Allerand wastewater treatment plant serves Montchenot, France, with advanced treatment for 2,416 people. It discharges 431 m³/day and has a designed capacity of 4,300 m³/day.
The Villers-Allerand wastewater treatment plant is located in Montchenot, a commune in the Marne department of the Grand Est region, France. It serves a population of approximately 2,416 residents, providing advanced treatment to protect local water quality. The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels for agglomerations of this size. With a designed capacity of 4,300 m³/day and a current discharge volume of 431 m³/day, the facility has ample capacity for future growth. The advanced treatment level ensures high-quality effluent. The treated effluent is discharged into the local watershed, which ultimately drains into the Vesle River and then the Aisne River, a tributary of the Oise and Seine rivers. This contributes to the protection of the Seine basin ecosystem, supporting aquatic life and downstream water quality.
Environmental context
The plant discharges into the Vesle River basin, which flows into the Aisne River and eventually the Seine River, reaching the English Channel. The Seine basin supports diverse aquatic habitats and is an important ecological corridor in northern France. Advanced treatment helps minimize nutrient loading and protects sensitive downstream environments.
