Overview
Yffiniac wastewater treatment plant serves Langueux, France, in the Bretagne region. It treats wastewater for approximately 45,510 people and is located near the coast.
Yffiniac wastewater treatment plant is located in Langueux, a commune in the Côtes-d'Armor department of Bretagne, France. The plant serves a population of approximately 45,510 people, placing it in the medium agglomeration category under French and EU regulations. It is situated near the coast, within 50 km of the shoreline, and its address is Rue du Moulin Héry, Station d'Épuration de Saint-Brieuc. As a French wastewater treatment plant serving a population of over 15,000, Yffiniac operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For agglomerations of this size, especially in sensitive areas, tertiary treatment may be mandated to reduce nutrient pollution. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating it is sized to handle the local load. The plant discharges treated effluent into the local watershed, which ultimately drains into the English Channel via the Bay of Saint-Brieuc. This coastal environment supports diverse marine life and is important for local fisheries and tourism. Proper treatment helps protect water quality in the bay and downstream ecosystems.
Environmental context
The Yffiniac plant discharges into the watershed of the Bay of Saint-Brieuc, a coastal inlet of the English Channel. This area supports diverse aquatic life, including fish and shellfish, and is an important ecological and economic resource for the region. The plant's proximity to the coast means that treated effluent must meet stringent standards to prevent nutrient enrichment and protect marine habitats.
