The STRASBOURG wastewater treatment plant is a major municipal facility located in the Port Autonome de Strasbourg, Robertsau district, serving the city of Strasbourg and surrounding areas in the Grand Est region of France. With a population equivalent of 850,000, it ranks among the largest treatment plants in the country, reflecting the dense urban and industrial character of the Strasbourg metropolitan area. As a large agglomeration exceeding 150,000 population equivalent, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires tertiary treatment for discharges into sensitive areas. The Rhine River basin, into which the plant ultimately discharges, is designated as sensitive due to eutrophication risks, necessitating nutrient removal (nitrogen and phosphorus) beyond secondary treatment. The plant's treatment process likely includes biological treatment with nutrient reduction, though specific process details are not publicly available. The treated effluent is discharged into the Rhine River via the Port Autonome de Strasbourg canal system. The Rhine is one of Europe's most important waterways, flowing through Germany and the Netherlands before reaching the North Sea. The plant plays a critical role in protecting the Rhine's water quality, supporting aquatic biodiversity, and ensuring compliance with international agreements such as the Rhine Protection Convention.
Environmental context
The plant discharges into the Rhine River, which flows through Germany and the Netherlands to the North Sea. The Rhine basin supports diverse aquatic life, including migratory fish species such as salmon and eel. Nutrient loading from urban and agricultural sources has historically caused eutrophication in the North Sea, making advanced treatment at large plants like STRASBOURG essential for downstream ecosystem health.
Frequently asked questions
The plant is located at Route du Glaserswoerth, Port Autonome de Strasbourg, in the Robertsau district of Strasbourg, Grand Est, France.
The plant serves approximately 850,000 people, making it a large agglomeration under EU classification.
Treated effluent is discharged into the Rhine River via the Port Autonome de Strasbourg canal system, ultimately flowing to the North Sea.
As a large agglomeration in France, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires tertiary treatment for discharges into sensitive areas like the Rhine basin.
Plants of this scale in France typically employ advanced biological treatment with nutrient removal (nitrogen and phosphorus) to meet EU standards for sensitive areas, often including tertiary filtration or disinfection.
