CANDE rue VLassalle Wastewater Treatment Plant, Candé, Pays de la Loire

CANDE rue VLassalle is an advanced wastewater treatment plant located in Candé, a commune in the Maine-et-Loire department of Pays de la Loire, France. The plant serves a population of about 4,960 and has a designed capacity of 5,000 m³/day, with an average discharge volume of 884.85 m³/day. As an advanced treatment facility, the plant goes beyond secondary treatment to remove nutrients and other pollutants, aligning with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The plant's scale places it in the small agglomeration category, for which secondary treatment is typically mandated, but the advanced level indicates additional environmental protection measures. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River basin. The Loire is a major European river that flows into the Atlantic Ocean, supporting diverse aquatic ecosystems and providing water for agriculture and human use. The plant's advanced treatment helps protect downstream water quality and ecological health.

The plant discharges into the local water system within the Loire River basin, which flows westward through the Pays de la Loire region and empties into the Bay of Biscay in the Atlantic Ocean. The Loire estuary is an ecologically sensitive area that supports migratory fish species such as Atlantic salmon and European eel, as well as diverse bird populations. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters.
