Dommartin-lès-Remiremont Wastewater Treatment Plant, Grand Est, France

The Dommartin-lès-Remiremont wastewater treatment plant is located in the Vosges department of the Grand Est region, France. It serves a population of approximately 5,850 residents in the commune of Dommartin-lès-Remiremont and surrounding areas. As a medium-sized agglomeration, the plant plays a key role in managing local wastewater within the Moselle River basin. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent between 2,000 and 10,000 are required to provide secondary treatment. This plant, serving 5,850 people, falls within this category and is expected to meet the directive's standards for biological treatment and nutrient removal where necessary. The regulatory framework ensures compliance with European water quality standards. The treated effluent is discharged into local watercourses that ultimately flow into the Moselle River, a major tributary of the Rhine. The Moselle basin supports diverse aquatic ecosystems and is an important water resource for the region. The plant's operations contribute to protecting downstream water quality and the ecological health of the Rhine-Moselle watershed.

The plant discharges into the Moselle River basin, which drains into the Rhine River and eventually the North Sea. The Moselle supports diverse aquatic life, including fish species such as grayling and barbel, and provides habitat for migratory birds. The region's forested watershed and moderate climate influence runoff patterns, making consistent treatment essential to prevent nutrient enrichment and maintain ecological balance in downstream waters.
