ST GOBAIN is a wastewater treatment plant located in Barisis-aux-Bois, a commune in the Aisne department of Hauts-de-France, France. The plant serves a population of approximately 2,662 and is situated in a rural area near the city of Laon. As a municipal facility, it plays a key role in managing local wastewater for this small agglomeration. 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 3,000 m³/day and an actual discharge volume of 474.90 m³/day, the plant operates well within its capacity, indicating room for future growth or seasonal fluctuations. The treated effluent is discharged into a local watercourse that ultimately drains into the Oise River basin, a major tributary of the Seine River. The Seine flows through Paris and into the English Channel, making the plant's advanced treatment important for protecting downstream water quality and the sensitive estuarine environment of the Seine Bay.
Environmental context
The plant discharges into a local stream that feeds into the Oise River, a major tributary of the Seine. The Seine River basin supports diverse aquatic life and is an important ecological corridor in northern France. The Seine estuary and Bay of Seine are ecologically sensitive areas that benefit from reduced nutrient loads provided by advanced treatment at upstream plants like ST GOBAIN.
