Overview
AY wastewater treatment plant serves Aÿ-Champagne, France, a community of about 6,000 people. Located in the Grand Est region, it discharges into the local watershed.
The AY wastewater treatment plant is located in Aÿ-Champagne, a commune in the Marne department of the Grand Est region, France. It serves a population of approximately 6,042 residents, placing it in the small-to-medium agglomeration category under French regulations. As a French facility, the plant operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (between 2,000 and 10,000 population equivalent), the directive requires secondary treatment or equivalent. It is expected to meet these standards. The treated effluent is discharged into the local water system, 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 and Seine river ecosystems from nutrient pollution and pathogens.
Environmental context
The plant discharges into the Marne River basin, which flows into the Seine River and eventually the English Channel. The Marne supports diverse aquatic life and is used for recreation and drinking water downstream. Protecting this watershed from nutrient loading and contaminants is critical for the ecological health of the Seine estuary and coastal waters.
