Overview
RUE DE TOUL wastewater treatment plant serves Calais, Hauts-de-France, France, with a population equivalent of 73,833. It is located within 50 km of the coast, discharging into the English Channel.
The RUE DE TOUL wastewater treatment plant is a municipal facility serving the city of Calais in the Hauts-de-France region of northern France. With a population served of 73,833, it falls under the EU classification of a medium agglomeration (10,000 to 150,000 PE). The plant is situated near the coast, within 50 km of the English Channel, which influences its discharge requirements. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, transposed into French law. For agglomerations of this size, the directive mandates secondary treatment as a minimum, with tertiary treatment required if the receiving waters are designated as sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating a moderate scale. The treated effluent from the plant is discharged into local waterways that ultimately flow into the English Channel. This coastal discharge requires compliance with stringent standards to protect marine ecosystems. The plant plays a key role in safeguarding the water quality of the Calais region and the broader marine environment of the Channel.
Environmental context
The plant's discharge enters the drainage network of the Calais region, which flows into the English Channel, a vital marine ecosystem supporting diverse aquatic life and migratory species. The Channel is a busy shipping lane and a sensitive marine environment, requiring careful management of nutrient and pollutant loads to prevent eutrophication and protect biodiversity.
