AVESNES LE COMTE SE is a municipal wastewater treatment plant located in Avesnes-le-Comte, a commune in the Pas-de-Calais department of the Hauts-de-France region, northern France. The plant serves a population of approximately 3,900 residents, classifying it as a small agglomeration under French and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. Its designed capacity is 2,000 m³/day, with an average daily discharge volume of about 696 m³, indicating operational headroom. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local watercourse, likely a tributary of the Scarpe or Canche river systems, which ultimately flow into the English Channel. The plant plays a key role in protecting local streams and groundwater from untreated sewage, supporting the ecological health of the region's waterways.
Environmental context
The plant discharges into a small river in the Artois region, part of the Scheldt basin that drains into the North Sea. The local watershed supports agricultural land and small wetlands, providing habitat for amphibians and waterfowl. Downstream, the water flows through the Scarpe river system, which is ecologically sensitive due to historical pollution and ongoing restoration efforts. The plant's secondary treatment helps reduce nutrient loading, protecting downstream aquatic life.
