Migennes Wastewater Treatment Plant: Serving 17,400 Residents in Bourgogne-Franche-Comté

The Migennes wastewater treatment plant is located in the commune of Migennes, within the Yonne department of Bourgogne-Franche-Comté, France. Serving an estimated population of 17,416, the plant is part of the region's municipal wastewater infrastructure, handling domestic sewage from the local community. As a French facility, Migennes operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent between 10,000 and 150,000. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Yonne River, a tributary of the Seine. The Seine River flows through Paris and into the English Channel, supporting diverse aquatic ecosystems along its course. Proper treatment at Migennes helps protect downstream water quality and ecological health.

The Migennes plant discharges into the Yonne River basin, which flows into the Seine River and eventually reaches the English Channel. The Seine estuary and downstream marine environment support diverse aquatic life, including migratory fish species. Effective wastewater treatment is crucial to prevent nutrient loading and maintain water quality in this ecologically sensitive river system.
