BLANZY Wastewater Treatment Plant, Blanzy, Bourgogne-Franche-Comté, France

The BLANZY wastewater treatment plant is located in Blanzy, a town in the Saône-et-Loire department of Bourgogne-Franche-Comté, France. The facility serves a population of approximately 15,732, classifying it as a medium-sized agglomeration under European Union regulations. As a French plant, BLANZY operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. 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 Loire River basin. The Loire is France's longest river and supports diverse aquatic ecosystems, including migratory fish species. Proper treatment helps protect downstream water quality and ecological health.

The BLANZY plant discharges into the local water system, which is part of the Loire River basin. The Loire flows through central France before reaching the Atlantic Ocean, supporting a variety of habitats including wetlands and floodplains. The river is ecologically sensitive, hosting species such as Atlantic salmon and European eel. Effective wastewater treatment is crucial to prevent nutrient pollution and maintain water quality in this important watershed.
