MONTCORNET nouvelle Wastewater Treatment Plant, Chaourse, Hauts-de-France

MONTCORNET nouvelle is an advanced wastewater treatment plant located at 5 Rue du Stade in Chaourse, a commune in the Aisne department of Hauts-de-France, France. The plant serves a population of approximately 1,850 people, reflecting its role in managing municipal wastewater for this small agglomeration. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 4,400 m³/day and a reported discharge volume of 330.04 m³/day, the facility operates well within its capacity. As a French plant, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment levels based on the size of the agglomeration and the sensitivity of the receiving environment. The treated effluent is discharged into local watercourses that ultimately drain into the Seine River basin, contributing to the overall water quality management of the region. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the Seine watershed.

MONTCORNET nouvelle discharges treated wastewater into local streams that are part of the Seine River basin, which flows through northern France before reaching the English Channel. The Seine basin supports diverse aquatic life and is an important ecological corridor. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality and mitigating eutrophication risks in the river and coastal zone.
