Montbazon Les Bourroux Wastewater Treatment Plant, Montbazon, France

The Montbazon Les Bourroux wastewater treatment plant is located in Montbazon, a commune in the Indre-et-Loire department of the Centre-Val de Loire region, France. The plant serves a population of approximately 8,200 people, placing it in the small to medium agglomeration category under French regulations. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide secondary treatment as a minimum. French law transposes this directive through the Code de l'environnement, and plants are typically operated by municipal or inter-municipal authorities. It is expected to meet the regulatory standards for its population tier. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River via the Indre River. The Loire is a major European river that flows into the Atlantic Ocean, supporting diverse aquatic ecosystems and providing water for agriculture and recreation. The plant plays a key role in protecting the water quality of the Indre and Loire rivers.

The plant discharges into the Indre River, a tributary of the Loire River. The Loire basin is one of the largest in France, supporting a rich biodiversity including migratory fish species such as Atlantic salmon and European eel. The downstream environment includes the Loire estuary, an ecologically sensitive area that provides critical habitat for birds and aquatic life. Proper wastewater treatment is essential to prevent nutrient pollution and maintain the ecological health of this river system.
