Trith St Leger, Trith-Saint-Léger

Overview

Trith St Leger wastewater treatment plant serves Trith-Saint-Léger in Hauts-de-France, France. It treats wastewater for approximately 11,175 people under the EU Urban Waste Water Treatment Directive.

The Trith St Leger wastewater treatment plant is located in Trith-Saint-Léger, a commune in the Nord department of Hauts-de-France, France. The facility serves a population of around 11,175 people, placing it in the medium agglomeration category under EU regulations. As a French plant, it 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 advanced treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The treated effluent from the plant is discharged into local waterways that ultimately drain into the Escaut (Scheldt) River basin. This river flows through northern France and Belgium before reaching the North Sea. The plant plays a key role in protecting the water quality of the Escaut basin and downstream ecosystems.

Environmental context

The plant discharges into the Escaut (Scheldt) River basin, which flows through Hauts-de-France and into Belgium, eventually reaching the North Sea. The Escaut is an ecologically important river that supports diverse aquatic life and is used for agriculture, industry, and recreation. Protecting its water quality is critical for the health of the river and the North Sea coastal environment.
