MOUZON Wastewater Treatment Plant, Mouzon, Grand Est, France

The MOUZON wastewater treatment plant is located in Mouzon, a commune in the Ardennes department of the Grand Est region, France. It serves a population of approximately 3,000 people, reflecting its role as a small municipal facility in a rural setting. The plant is situated near the Meuse River, which is the primary watercourse in the area. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 4,500 m³/day and an actual discharge volume of 535.19 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. As a French wastewater treatment plant, it operates under the national regulations transposing the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on population equivalents and receiving water sensitivity. The treated effluent is discharged into the local watershed, ultimately flowing into the Meuse River. The Meuse River is a major European waterway that traverses France, Belgium, and the Netherlands before emptying into the North Sea. The plant's advanced treatment helps protect the river's water quality, supporting aquatic life and downstream uses such as drinking water production and recreation.

The MOUZON plant discharges into the Meuse River basin, which drains through the Ardennes region into Belgium and the Netherlands, eventually reaching the North Sea. The Meuse River supports diverse aquatic ecosystems, including fish species such as grayling and brown trout. The advanced treatment at this plant helps minimize nutrient and pollutant loads, reducing the risk of eutrophication and maintaining ecological balance in the river and its downstream environments.
