REMILLY Wastewater Treatment Plant, Rémilly, Grand Est, France

The REMILLY wastewater treatment plant is located in Rémilly, a commune in the Moselle department of the Grand Est region, France. The plant serves a population of approximately 2,700 residents and has a designed capacity of 3,500 cubic meters per day, with an average discharge volume of 481.68 cubic meters per day. As an advanced treatment facility, REMILLY goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. This level of treatment is typical for plants in sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for agglomerations discharging into sensitive water bodies. The plant's treated effluent is discharged into the local watershed, which drains into the Nied River, a tributary of the Saar River, and ultimately into the Moselle and Rhine rivers. The Rhine basin supports diverse aquatic ecosystems and is an important migratory corridor for fish species. The advanced treatment helps protect downstream water quality and ecological health.

The REMILLY plant discharges into the Nied River, which flows into the Saar River, then the Moselle River, and finally the Rhine River. The Rhine basin is a major European waterway supporting diverse aquatic life and migratory fish. The advanced treatment at REMILLY helps reduce nutrient loading, protecting downstream ecosystems from eutrophication.
