AVESNES LES AUBERT RIEUX EN CAMBRESIS SE Wastewater Treatment Plant, Rieux-en-Cambrésis, France

AVESNES LES AUBERT RIEUX EN CAMBRESIS SE is a wastewater treatment plant located in Rieux-en-Cambrésis, a commune in the Nord department of Hauts-de-France, France. The plant serves a population of approximately 13,695 people, placing it in the medium agglomeration category under French and EU regulations. As a French wastewater facility, the plant 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 tertiary treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures appropriate treatment standards. The plant discharges treated effluent into the local water system, which ultimately drains into the Scheldt River basin. The Scheldt flows through northern France and Belgium before reaching the North Sea. The plant plays a key role in protecting the water quality of the Scheldt catchment and downstream ecosystems.

The plant's treated effluent enters the local water network that feeds into the Scheldt River, which flows through the Hauts-de-France region and into Belgium before discharging into the North Sea. The Scheldt basin supports diverse aquatic life and is an important ecological corridor for migratory fish species. The plant's operations help maintain water quality in this transboundary river system, which is subject to EU water quality standards under the Water Framework Directive.
