STE MENEHOULD Wastewater Treatment Plant, Sainte-Menehould, Grand Est, France

The STE MENEHOULD wastewater treatment plant is located in Sainte-Menehould, a commune in the Marne department of the Grand Est region, France. The plant serves a population of approximately 5,200 residents and is situated near the municipal stadium, along the Route de Chaudefontaine. It operates as a key component of the local sanitation infrastructure. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 7,000 m³/day and a current discharge volume of 927.67 m³/day, the facility has ample capacity to handle peak flows. The advanced treatment level ensures high-quality effluent suitable for discharge into sensitive environments. The treated effluent is discharged into the local watershed, which ultimately drains into the Aisne River, a tributary of the Oise and then the Seine. The Seine River flows through Paris and into the English Channel. The plant's advanced treatment helps protect the ecological health of these downstream water bodies, supporting aquatic life and water quality in the Seine basin.

The plant discharges into the local watershed that feeds the Aisne River, a tributary of the Oise River, which joins the Seine River. The Seine flows through the Paris metropolitan area and eventually reaches the English Channel. The advanced treatment provided by the plant helps protect the Seine basin's aquatic ecosystems, including fish populations and migratory species, from nutrient pollution and other contaminants.
