Overview
LIGNY LE CHATEL wastewater treatment plant in Ligny-le-Châtel, Bourgogne-Franche-Comté, France, serves 1,900 people with advanced treatment and a designed capacity of 2,000 m³/day.
The LIGNY LE CHATEL wastewater treatment plant is located in Ligny-le-Châtel, a commune in the Yonne department of Bourgogne-Franche-Comté, France. The facility serves a population of approximately 1,900 and has a designed capacity of 2,000 cubic meters per day, with an average discharge volume of 338.96 m³/day. As an advanced treatment plant, it goes beyond the secondary treatment requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant's advanced treatment likely includes nutrient removal, which is important for protecting sensitive receiving waters in the region. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Seine River basin via the Yonne River. This river system supports diverse aquatic life and provides water for downstream communities and agriculture. The advanced treatment helps minimize nutrient loading and protect water quality in the Seine estuary and the English Channel.
Environmental context
The plant discharges into the Yonne River, a tributary of the Seine River, which flows through Paris and into the English Channel. The Seine basin supports a rich ecosystem, including migratory fish species such as Atlantic salmon and eel. Advanced treatment at this plant reduces nutrient pollution, helping to prevent eutrophication in downstream waters and the coastal marine environment.
