Overview
CLOHARS CARNOET wastewater treatment plant serves Le Pouldu in Brittany, France, with a designed capacity of 1.00 (unit unspecified) and a population equivalent of 7,570. The plant is located within 50 km of the coast, discharging into the local wate
The CLOHARS CARNOET wastewater treatment plant is located in Le Pouldu, a coastal village in the Finistère department of Brittany, France. As a French wastewater treatment plant, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations with a population equivalent between 2,000 and 10,000, the directive requires secondary treatment (biological treatment) as a minimum standard. It is expected to meet these regulatory requirements. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the coastal waters of the Bay of Biscay. The receiving environment includes the Laita River estuary and adjacent marine areas, which support diverse aquatic life and are important for local fisheries and tourism. The proximity to the coast (within 50 km) underscores the need for effective nutrient removal to prevent eutrophication in sensitive coastal waters.
Environmental context
The plant discharges into the Laita River basin, which flows into the Atlantic Ocean near Le Pouldu. This coastal area is part of the Bay of Biscay, a productive marine ecosystem supporting fish stocks and migratory birds. The watershed includes estuarine habitats that are sensitive to nutrient enrichment from wastewater, making proper treatment essential for maintaining water quality and ecological balance.
