Overview
ROSHEIM wastewater treatment plant serves the town of Rosheim in Grand Est, France. It treats wastewater for approximately 11,000 residents under the EU Urban Waste Water Treatment Directive.
The ROSHEIM wastewater treatment plant is located in Rosheim, a commune in the Bas-Rhin department of the Grand Est region in northeastern France. The facility serves a population of around 11,000 people, placing it in the medium agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). Under the EU UWWTD, agglomerations with a population equivalent (PE) between 2,000 and 10,000 are generally required to have secondary treatment, while those above 10,000 PE must meet more stringent standards if discharging into sensitive areas. As a plant serving 11,000 people, ROSHEIM is expected to provide at least secondary treatment, with possible tertiary treatment if the receiving environment is sensitive. The plant discharges treated wastewater into local watercourses that ultimately drain into the Rhine River basin. The Rhine is a major European waterway that flows through Germany and the Netherlands into the North Sea. The plant's operations contribute to protecting the water quality of the Rhine basin and the downstream aquatic ecosystems.
Environmental context
The ROSHEIM plant discharges into the local watershed that feeds the Ill River, a tributary of the Rhine. The Rhine River is one of Europe's most important waterways, supporting diverse aquatic life and providing drinking water for millions. The plant's treatment helps reduce nutrient and pollutant loads entering the Rhine, protecting downstream ecosystems including the Rhine delta and the North Sea.
