CIVRAY DE TOURAINE Varenne de Chenonceaux Wastewater Treatment Plant, Civray-de-Touraine, France

CIVRAY DE TOURAINE Varenne de Chenonceaux is an advanced wastewater treatment plant located in Civray-de-Touraine, in the Centre-Val de Loire region of France. The plant serves a population of approximately 2,900 people and has a designed capacity of 4,000 cubic meters per day, with an average discharge volume of 517.35 cubic meters per day. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment is typically implemented in sensitive areas to reduce nutrient loads and protect receiving water bodies. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River, one of France's major rivers. The Loire River supports diverse aquatic ecosystems and is an important ecological corridor. The advanced treatment helps minimize the environmental impact on downstream water quality and biodiversity.

The plant discharges into the local watercourse that flows into the Loire River, which eventually reaches the Atlantic Ocean. The Loire basin is ecologically significant, supporting diverse fish populations and migratory species. Advanced treatment at this plant helps reduce nutrient pollution, protecting the river's sensitive ecosystems and downstream coastal waters.
