ST GERMER DE FLY Wastewater Treatment Plant, Saint-Germer-de-Fly, Hauts-de-France

ST GERMER DE FLY is a wastewater treatment plant located in Saint-Germer-de-Fly, a commune in the Oise department of Hauts-de-France, France. The plant serves a population of approximately 2,236 residents and is designed to handle a capacity of 2,000 cubic meters per day, with an actual discharge volume of 398.9 cubic meters per day. It operates under the French regulatory framework, which implements the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this scale. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. As a small agglomeration (under 10,000 population equivalent), it meets the directive's requirements for appropriate treatment to protect the local environment. The facility is situated inland, more than 10 km from the coast, and its treated effluent is discharged into local watercourses that ultimately drain into the Seine River basin. The plant plays a key role in safeguarding the water quality of the surrounding watershed, which supports diverse aquatic life and contributes to the ecological health of the Seine River system. By providing advanced treatment, it helps reduce nutrient loads and other pollutants that could impact downstream ecosystems, including the Seine estuary and the English Channel.

The plant discharges treated wastewater into local streams that are part of the Seine River basin, which flows through northern France and empties into the English Channel. The watershed supports a variety of freshwater habitats and is important for regional biodiversity. Advanced treatment at this facility helps protect the ecological integrity of the receiving waters, reducing the risk of eutrophication and other pollution impacts on downstream environments.
