MARMOUTIER is a wastewater treatment plant located in Marmoutier, a commune in the Bas-Rhin department of the Grand Est region, France. The plant serves a population of 4,800 and is part of the region's municipal wastewater infrastructure, operating under French regulations that transpose the EU Urban Waste Water Treatment Directive. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU directive for agglomerations of this size. With a designed capacity of 5,500 m³/day and an actual discharge volume of 856.31 m³/day, the facility operates well within its capacity, ensuring effective treatment of wastewater from the local community. The treated effluent is discharged into the local watershed, which ultimately drains into the Rhine River basin. The Rhine is a major European waterway that flows through Germany and the Netherlands into the North Sea. The advanced treatment helps protect the sensitive aquatic ecosystems of the Rhine basin, supporting biodiversity and water quality downstream.

The plant discharges into the local water system that feeds into the Rhine River basin. The Rhine is a critical waterway in Europe, supporting diverse aquatic life and providing drinking water for millions. The advanced treatment at MARMOUTIER helps reduce nutrient loads and pollutants, protecting the ecological health of the river and its downstream environments, including the Rhine delta and the North Sea.
