JOIGNY Wastewater Treatment Plant, Joigny, Bourgogne-Franche-Comté, France

The JOIGNY wastewater treatment plant is located in Joigny, a commune in the Yonne department of Bourgogne-Franche-Comté, France. The plant serves a population of approximately 12,553, classifying it as a medium agglomeration under EU regulations. It is situated inland, away from coastal areas, and its operations are part of the regional wastewater infrastructure managed by local authorities. As a plant serving a population between 10,000 and 150,000, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum standard. The directive ensures that the plant meets regulatory standards for effluent quality before discharge. The plant's design capacity and operational status are consistent with typical facilities of this scale in France. The treated effluent from the JOIGNY plant 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, making the plant's operations important for downstream water quality. The plant helps protect the ecological health of the Yonne and Seine rivers, supporting aquatic life and recreational uses.

The JOIGNY plant discharges into the Yonne River, which flows into the Seine River and eventually reaches the English Channel. The Seine basin supports diverse aquatic ecosystems and is a vital water resource for agriculture, industry, and drinking water. The plant's treatment helps reduce nutrient and pollutant loads, protecting downstream habitats and water quality in this ecologically sensitive region.
