CHAULNES SE is a municipal wastewater treatment plant located in the industrial zone of Chaulnes Sud, in the commune of Punchy, within the Somme department of Hauts-de-France, France. The plant serves a population of approximately 1,880 people and is designed to handle a capacity of 3,216 m³ per day, with an average discharge volume of 335.39 m³ per day. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with EU effluent quality standards before discharge. The treated effluent is discharged into the local watershed, which ultimately drains into the Somme River and then into the English Channel. The plant plays a key role in protecting the water quality of the Somme basin, supporting aquatic life and downstream ecosystems in this agriculturally intensive region.
Environmental context
The plant discharges into the Somme River basin, which flows through the Hauts-de-France region before reaching the English Channel. The Somme is an ecologically important river supporting diverse fish populations and wetland habitats. The plant's secondary treatment helps reduce nutrient and organic pollution, mitigating eutrophication risks in the downstream estuary and coastal waters.
