COUBERT Wastewater Treatment Plant, Coubert, Seine-et-Marne, France

The COUBERT wastewater treatment plant is located in Coubert, a commune in the Seine-et-Marne department of north-central France. It serves a population of approximately 1,830 residents and is part of the municipal wastewater infrastructure managed by the local authority. The plant is situated inland, away from coastal areas, and its operations are regulated under French and European environmental standards. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. It has a designed capacity of 3,400 m³/day and currently treats an average daily volume of 326.47 m³, indicating significant spare capacity. As an advanced treatment facility, it likely includes nutrient removal stages, which are typical for plants in sensitive catchment areas under the EU Urban Waste Water Treatment Directive. The treated effluent from COUBERT is discharged into local watercourses that eventually drain into the Seine River basin. The Seine flows through Paris and into the English Channel, supporting diverse aquatic ecosystems and providing water for agriculture and industry. The plant's advanced treatment helps protect downstream water quality and ecological health.

The COUBERT plant discharges into the Seine River basin, which flows through the Île-de-France region and ultimately reaches the English Channel. The Seine supports a variety of fish species and is an important migratory corridor for eels and salmon. The plant's advanced treatment helps reduce nutrient loads, mitigating eutrophication risks in the river and its estuary.
