Overview
ARQUES LA BATAILLE is an advanced wastewater treatment plant in Arques-la-Bataille, Normandy, France, serving 5,100 people. It discharges 909.83 m³/day of treated effluent and is located within 10 km of the coast.
ARQUES LA BATAILLE wastewater treatment plant serves the commune of Arques-la-Bataille in the Seine-Maritime department of Normandy, France. The plant treats wastewater from a population of approximately 5,100 residents and is situated near the coastal town of Dieppe. As an advanced treatment facility, it provides a higher level of pollutant removal beyond secondary treatment, which is typical for sensitive areas under French and EU regulations. The plant has a designed capacity of 2,600 m³/day and currently discharges an average of 909.83 m³/day of treated wastewater. The advanced treatment level indicates the use of technologies such as nutrient removal or disinfection. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size (5,100 PE) are required to provide secondary treatment, but the advanced level suggests the plant operates in a sensitive area where tertiary treatment is mandated. The treated effluent is discharged into the local watershed, which ultimately drains into the English Channel near Dieppe. The coastal location means the plant plays a critical role in protecting marine water quality and supporting local ecosystems, including shellfish waters and bathing areas along the Normandy coast.
Environmental context
The plant discharges into the coastal waters of the English Channel near Dieppe, a region known for its diverse marine life and important fisheries. The receiving environment includes estuaries and intertidal zones that support migratory birds and commercial shellfish beds. Advanced treatment helps minimize nutrient loading and pathogen release, which is essential for maintaining water quality in this ecologically sensitive coastal area.
Frequently asked questions
The plant is located in Arques-la-Bataille, a commune in the Seine-Maritime department of Normandy, France, near the coastal city of Dieppe.
The plant serves approximately 5,100 residents of Arques-la-Bataille and surrounding areas.
The plant discharges treated effluent into the local watershed, which flows into the English Channel near Dieppe. The advanced treatment level ensures high-quality effluent to protect coastal water quality.
The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations over 2,000 PE and tertiary treatment in sensitive areas. The advanced treatment level indicates compliance with stricter standards for coastal protection.
In France, plants serving 5,100 people typically provide secondary treatment as a minimum. However, if located in a sensitive area (e.g., coastal zone), advanced treatment with nutrient removal is required to prevent eutrophication and protect marine ecosystems.
