LAMBALLE Souleville Wastewater Treatment Plant, Lamballe-Armor, Bretagne

The LAMBALLE Souleville wastewater treatment plant is located in Lamballe-Armor, a commune in the Côtes-d'Armor department of Bretagne, France. The plant serves a population of approximately 70,600 people, classifying it as a medium to large agglomeration under French and EU regulations. Its location near the coast places it within a sensitive environmental zone. As a French wastewater treatment facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. For plants in coastal areas, the directive may also mandate additional treatment to protect marine environments. The plant's designed capacity is 1. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the English Channel via the Baie de Saint-Brieuc. This coastal area supports diverse marine life and is important for local fisheries and tourism. The plant's proximity to the coast underscores the need for effective treatment to minimize nutrient and pollutant loads entering the marine ecosystem.

The plant discharges into the Baie de Saint-Brieuc, a coastal embayment of the English Channel. This area supports diverse marine habitats, including seagrass beds and shellfish populations, and is a key fishing ground. The watershed includes the Gouessant river and other small coastal streams. Effective wastewater treatment is critical to prevent eutrophication and protect the bay's ecological health and economic value.
