VERBERIE Wastewater Treatment Plant, Rhuis, Hauts-de-France

The VERBERIE wastewater treatment plant is located in Rhuis, a commune in the Oise department of Hauts-de-France, northern France. It serves a population of approximately 4,634 people, classifying it as a small agglomeration under French regulations. The plant is situated near the Oise River, a major tributary of the Seine. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland agglomerations of this size. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant's designed capacity is 4,000 m³/day, and it discharges an average volume of 826.70 m³/day, indicating operational capacity well within design limits. Treated effluent from the plant is discharged into the local watershed, which drains into the Oise River and eventually the Seine River, flowing into the English Channel. The Seine basin supports diverse aquatic life and is an important ecological corridor. The plant's operation helps protect downstream water quality in this sensitive river system.
