PLOERMEL La Ville Rehel Wastewater Treatment Plant, Ploërmel, Brittany

PLOERMEL La Ville Rehel is a wastewater treatment plant located in Ploërmel, a commune in the Morbihan department of Brittany, France. The plant serves a population of around 29,283, placing it in the medium agglomeration category under EU classification. As a French facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The designed capacity is 1.00 (likely in thousands of cubic meters per day or population equivalent), indicating a facility scaled to handle the local wastewater load. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Vilaine River or coastal streams. This discharge supports the ecological health of the region's waterways, which are important for aquatic biodiversity and migratory fish species.

The plant discharges into the local watershed in Brittany, which flows into the Vilaine River basin and eventually reaches the Atlantic Ocean. The downstream environment includes estuaries and coastal zones that support diverse aquatic life, including migratory fish such as salmon and eels. The region's water bodies are ecologically sensitive, and the plant's treatment helps protect water quality in this important coastal ecosystem.
