RODEMACK STATION AVAL Wastewater Treatment Plant, Évange, Grand Est

RODEMACK STATION AVAL is an advanced wastewater treatment plant located in Évange, a locality within the commune of Rodemack in the Grand Est region of France. The plant serves a population of 3,250 people, placing it in the small-to-medium agglomeration category under French and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,400 m³/day and a reported discharge volume of 579.79 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variability. The treated effluent is discharged into the local watershed, which ultimately drains into the Moselle River, a major tributary of the Rhine. The Rhine basin is a critical ecological corridor in Western Europe, supporting diverse aquatic life and providing water for millions of people. The plant's advanced treatment helps protect downstream water quality in this internationally important river system.

The plant discharges into the Moselle River basin, which flows into the Rhine River and eventually the North Sea. The Moselle is a key tributary of the Rhine, supporting diverse fish populations including salmonids and cyprinids. The advanced treatment level helps minimize nutrient loading and protect downstream aquatic ecosystems in this densely populated and industrialized region.
