DAMERY VENTEUIL Wastewater Treatment Plant, Damery, Grand Est

DAMERY VENTEUIL is an advanced wastewater treatment plant located in Damery, in the Grand Est region of France. The facility serves a population of approximately 3,267 residents and is designed to handle up to 5,000 cubic meters of wastewater per day, with a current discharge volume of 582.83 cubic meters. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a French facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas. For agglomerations of this size (under 10,000 population equivalent), the directive mandates appropriate treatment to protect receiving waters. The treated effluent is discharged into the local watershed, which ultimately drains into the Marne River, a major tributary of the Seine. The Seine flows through Paris and into the English Channel. The plant plays a key role in protecting the Marne River and downstream ecosystems from nutrient pollution and other contaminants.

The plant discharges into the Marne River basin, which feeds into the Seine River and eventually the English Channel. The Marne River supports diverse aquatic life and is used for recreation and drinking water supply downstream. Advanced treatment at this plant helps reduce nutrient loading, protecting the river from eutrophication and maintaining water quality for sensitive ecosystems in the Seine estuary.
