JARNY, Jarny | France Wastewater

Overview

JARNY wastewater treatment plant serves the commune of Jarny in Grand Est, France. It handles a population equivalent of 11,500 under the EU Urban Waste Water Treatment Directive.

The JARNY wastewater treatment plant is located in Tichémont, Jarny, within the Meurthe-et-Moselle department of the Grand Est region, France. The facility serves a population equivalent of 11,500, classifying it as a medium agglomeration under EU regulations. As a French plant, JARNY operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent discharging into freshwater. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The treated effluent from JARNY is discharged into the local watershed, which ultimately drains into the Moselle River, a major tributary of the Rhine. The Rhine basin supports diverse aquatic ecosystems and is an important migratory corridor for fish species. The plant plays a key role in protecting downstream water quality in this transboundary river system.

Environmental context

The JARNY plant discharges into the Moselle River basin, which flows through France, Luxembourg, and Germany before joining the Rhine. The Rhine is a major European waterway supporting diverse aquatic life, including salmon and eel populations. The plant's treatment helps reduce nutrient loads that could contribute to eutrophication in downstream water bodies, including the Rhine Delta and the North Sea.
