Overview
Dieuze wastewater treatment plant in Grand Est, France, serves approximately 3,950 people with advanced treatment. It discharges 704.67 m³/day and has a designed capacity of 6,800 m³/day.
Dieuze wastewater treatment plant is located in the commune of Dieuze, within the Moselle department of the Grand Est region in northeastern France. The facility serves a population of about 3,950 residents, reflecting a small to medium agglomeration under French and EU classification. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 6,800 m³/day and an actual discharge volume of 704.67 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately drain into the Rhine basin, contributing to the overall water quality of the region. The plant's advanced treatment helps protect downstream ecosystems, including the Moselle River and its tributaries, which support diverse aquatic life and are important for regional biodiversity.
Environmental context
The plant discharges into the local watershed that feeds the Seille River, a tributary of the Moselle, which flows into the Rhine River and eventually the North Sea. The Moselle basin supports a variety of fish species and is an important ecological corridor. Advanced treatment at Dieuze helps reduce nutrient loads, protecting downstream water quality and aquatic habitats.
