Overview
Saint-Brieuc Le Legue wastewater treatment plant serves the city of Saint-Brieuc in Brittany, France, with a population equivalent of over 118,000. It is located near the coast and discharges into the local watershed.
The Saint-Brieuc Le Legue wastewater treatment plant is a key municipal facility serving the city of Saint-Brieuc in the Brittany region of France. With a population served of over 118,000, it is classified as a large agglomeration under European Union regulations. The plant is situated near the coast, reflecting the importance of managing wastewater in a coastal urban environment. As a large agglomeration, the plant is expected to meet the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum and tertiary treatment in sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per day or a similar unit), indicating its scale. The regulatory framework ensures compliance with discharge standards. Given its coastal proximity, treated effluent likely discharges into the English Channel via local rivers or directly. The downstream environment includes the Bay of Saint-Brieuc, which supports diverse marine life and is an important area for fisheries and tourism. The plant plays a crucial role in protecting this coastal ecosystem from nutrient pollution and pathogens.
Environmental context
The plant is located in the Baie de Saint-Brieuc watershed, which drains into the English Channel. The bay is ecologically sensitive, supporting diverse marine habitats including seagrass beds and shellfish populations. Treated effluent from the plant must meet stringent standards to prevent eutrophication and protect water quality in this coastal zone, which is also important for recreational activities and local fisheries.
