Overview
Cattenom wastewater treatment plant serves the Sentzich area in Grand Est, France. It provides advanced treatment for a population of 3,400 with a designed capacity of 4,000 m³/day.
The Cattenom wastewater treatment plant is located in Sentzich, a locality within the commune of Cattenom in the Moselle department of Grand Est, France. It serves a population of approximately 3,400 people and has a designed capacity of 4,000 m³/day, with an average discharge volume of 606.55 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, aligning with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The plant's advanced treatment level ensures high-quality effluent before discharge. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Moselle River, a major tributary of the Rhine. The Rhine basin supports diverse aquatic life and is an important ecological corridor in Western Europe. The advanced treatment helps protect downstream water quality and ecosystems.
Environmental context
The plant discharges into the Moselle River basin, which flows into the Rhine River and eventually the North Sea. The Moselle is a key waterway in the region, supporting fish populations and riparian habitats. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters and maintaining the ecological health of the Rhine basin.
Frequently asked questions
The Cattenom wastewater treatment plant is located in Sentzich, a locality within the commune of Cattenom in the Moselle department of Grand Est, France. Its address is D 64, Sentzich, Cattenom, Thionville, Moselle, Grand Est.
The Cattenom wastewater treatment plant serves a population of approximately 3,400 people in the Sentzich area and surrounding parts of Cattenom.
The Cattenom plant provides advanced treatment, which includes secondary biological treatment followed by additional nutrient removal (nitrogen and phosphorus). This level of treatment produces high-quality effluent suitable for discharge into sensitive water bodies.
The plant discharges into the local watershed that drains into the Moselle River, a major tributary of the Rhine. By providing advanced treatment, the plant helps protect the water quality of the Moselle and Rhine rivers, supporting aquatic ecosystems and downstream communities.
Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) above 10,000 in sensitive areas require advanced treatment. Although Cattenom serves fewer than 10,000 people, its advanced treatment level suggests it may be located in a sensitive area or voluntarily meets higher standards to protect the Moselle-Rhine basin.
