Overview
The LANGRES wastewater treatment plant serves approximately 29,000 people in Champigny-lès-Langres, Grand Est, France. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this size.
The LANGRES wastewater treatment plant is located in Champigny-lès-Langres, a commune in the Haute-Marne department of the Grand Est region, France. The plant serves a population of approximately 29,000, classifying it as a medium agglomeration under EU regulations. Its location near the Marne River places it within the Seine basin, a major hydrological system in northern France. As a plant serving a population equivalent of 29,000, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant's operational details, including specific treatment processes and capacity, are not publicly available in this dataset. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Marne River and then into the Seine River before reaching the English Channel. This waterway supports diverse aquatic life and is an important ecological corridor in the region. The plant's operation contributes to protecting water quality in the Seine basin, which is vital for both ecological health and human use downstream.
Environmental context
The plant's treated effluent enters the local tributary system of the Marne River, a major right-bank tributary of the Seine. The Seine River flows through Paris and into the English Channel, supporting a wide range of aquatic species and providing drinking water for millions. The watershed is ecologically sensitive, with efforts to reduce nutrient pollution to prevent eutrophication in coastal zones. The plant's location inland, more than 50 km from the coast, reduces direct marine impact but still influences the overall health of the Seine estuary.
