Chissay-en-Touraine la Varenne Wastewater Treatment Plant, Centre-Val de Loire, France

Chissay-en-Touraine la Varenne is a wastewater treatment plant located in Chissay-en-Touraine, within the Centre-Val de Loire region of France. The facility serves a population of approximately 11,205, classifying it as a medium-sized agglomeration under EU regulations. The plant is situated in the Loire River basin, an ecologically significant area known for its diverse aquatic habitats. 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 between 10,000 and 150,000 population equivalent. 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 treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Loire River. The Loire is one of France's longest rivers, flowing into the Atlantic Ocean. The river supports a variety of fish species and migratory birds, making the plant's role in protecting water quality crucial for downstream ecosystems and biodiversity.

The plant discharges into the Loire River basin, which flows through central France before reaching the Atlantic Ocean. The Loire is known for its diverse aquatic life, including Atlantic salmon and European eel, and its floodplain wetlands provide critical habitat for migratory birds. The plant's operations help maintain water quality in this ecologically sensitive river system.
