Overview
COUDEKERQUE BRANCHE wastewater treatment plant serves Dunkerque, France, with a population equivalent of 124,600. It operates under the EU Urban Waste Water Treatment Directive.
COUDEKERQUE BRANCHE is a wastewater treatment plant located in Dunkerque, Hauts-de-France, France. It serves a population equivalent of 124,600, classifying it as a large agglomeration under EU regulations. The plant is situated near the coast, within 50 km of the North Sea. As a large agglomeration in France, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum, and tertiary treatment if discharging into sensitive areas. The designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating a substantial infrastructure. The plant's treated effluent ultimately discharges into the North Sea via local waterways. The Dunkerque region is an industrial and port area, and the plant plays a key role in protecting the marine environment from nutrient pollution and pathogens. The North Sea supports diverse marine life and is an important fishing ground.
Environmental context
The plant discharges into the North Sea, a semi-enclosed sea with limited water exchange, making it sensitive to nutrient enrichment and eutrophication. The Dunkerque area is part of the coastal zone of the English Channel, which supports important fisheries and migratory bird populations. Proper treatment is essential to maintain water quality and protect marine ecosystems.
