CRUAS 2 Wastewater Treatment Plant, Cruas, France

CRUAS 2 is a wastewater treatment plant located in Cruas, a commune in the Ardèche department of the Auvergne-Rhône-Alpes region, France. The plant serves a population of approximately 8,082 people, placing it in the small to medium agglomeration category under French and EU regulations. As a French treatment plant, CRUAS 2 operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into freshwater. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures compliance with national and EU standards. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Rhône River, one of Europe's major waterways. The Rhône flows southward through the Camargue delta into the Mediterranean Sea. This discharge contributes to the ecological health of the river system, supporting diverse aquatic life and downstream ecosystems.

CRUAS 2 discharges into the local watershed that feeds the Rhône River, a major European river flowing through southeastern France. The Rhône basin supports diverse aquatic habitats and is an important migratory corridor for fish species. The river ultimately reaches the Mediterranean Sea via the Camargue delta, a region of high ecological value. The plant's operations are subject to EU regulations that protect sensitive areas and maintain water quality standards.
