SAINT LEONARD DE NOBLAT Pont de Noblat Wastewater Treatment Plant, Saint-Léonard-de-Noblat

SAINT LEONARD DE NOBLAT Pont de Noblat is a wastewater treatment facility located in Saint-Léonard-de-Noblat, a commune in the Haute-Vienne department of Nouvelle-Aquitaine, France. The plant serves a population of 2,795 and is situated near the Vienne River, which flows through the Limousin region. It operates under the French regulatory framework, which implements the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the EU directive for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant has a designed capacity of 2,500 cubic meters per day and reports a discharge volume of 498.62 cubic meters per day, indicating it operates well below capacity. The treated effluent is discharged into the Vienne River, a tributary of the Loire River. The Vienne River supports diverse aquatic life and is an important water resource for the region. The Loire River ultimately flows into the Atlantic Ocean, making the plant's discharge part of a larger watershed that requires careful management to prevent eutrophication and maintain water quality.

The plant discharges into the Vienne River, which flows into the Loire River, one of France's longest rivers, before reaching the Atlantic Ocean. The Vienne River watershed supports diverse aquatic ecosystems and is used for recreation and agriculture. Advanced treatment helps reduce nutrient loading, protecting downstream water bodies from eutrophication and maintaining ecological balance.
