Overview
QUIMPER Corniguel wastewater treatment plant serves 170,000 people in Quimper, Bretagne, France. The facility is located near the Odet River within 50 km of the coast.
QUIMPER Corniguel is a wastewater treatment plant serving the city of Quimper in the Bretagne region of France. With a population equivalent of 170,000, it is classified as a large agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant is situated at Les Sabliers de l'Odet in the Corniguel area, near the Odet River. As a large agglomeration, the plant is expected to provide at least secondary treatment, with tertiary treatment required if the receiving waters are designated as sensitive areas. The designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating the facility's scale. The plant operates under French national regulations implementing the EU directive, overseen by the local water agency. The plant discharges into the Odet River, which flows into the Bay of Biscay (Atlantic Ocean) near the coast of Finistère. The Odet estuary supports diverse aquatic life and is an important ecological corridor. The proximity to the coast (within 50 km) means treated effluent ultimately reaches marine waters, requiring careful management to protect coastal water quality.
Environmental context
The plant discharges into the Odet River, which flows through Quimper and into the Bay of Biscay, part of the Atlantic Ocean. The Odet estuary is ecologically sensitive, supporting diverse aquatic life including migratory fish species. The coastal waters near the mouth of the Odet are important for marine biodiversity and recreational activities. As the plant is within 50 km of the coast, its discharge can affect both freshwater and marine environments, necessitating compliance with EU water quality standards.
