Overview
PFAFFENHOFFEN wastewater treatment plant serves Niedermodern, Grand Est, France, treating wastewater for approximately 19,000 people under the EU Urban Waste Water Treatment Directive.
The PFAFFENHOFFEN wastewater treatment plant is located in Niedermodern, a commune in the Bas-Rhin department of the Grand Est region, France. The facility serves a population of around 19,000, classifying it as a medium agglomeration under EU regulations. It is situated inland, away from coastal areas, and its operations are governed by French national water laws transposing EU directives. As a plant serving between 10,000 and 100,000 people, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. The facility is part of France's extensive wastewater infrastructure, which is regulated by the French Ministry of Ecology and local water agencies. The treated effluent is discharged into the Moder River, a tributary of the Rhine. The Moder flows through the Alsace region before joining the Rhine, which ultimately drains into the North Sea. The plant plays a key role in protecting the local water quality and the downstream aquatic ecosystems of the Rhine basin.
Environmental context
The PFAFFENHOFFEN plant discharges into the Moder River, which flows into the Rhine River, a major European waterway that empties into the North Sea. The Rhine basin supports diverse aquatic life and is an important migratory corridor for fish species. The plant's treatment helps maintain water quality in this ecologically sensitive river system, which is subject to strict EU water quality standards.
