ANET Wastewater Treatment Plant, Anet, Centre-Val de Loire, France

ANET is an advanced wastewater treatment plant located in Anet, a commune in the Eure-et-Loir department of Centre-Val de Loire, France. The plant serves a population of approximately 2,882 and has a designed capacity of 6,000 m³/day, with a current discharge volume of 514.14 m³/day, indicating it operates well below its capacity. As an advanced treatment facility, ANET goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent European standards. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations between 2,000 and 10,000 population equivalent are required to provide secondary treatment, but ANET's advanced level suggests it may be in a sensitive area or subject to additional local requirements. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Seine River basin. The Seine flows through Paris and into the English Channel, supporting diverse aquatic life and providing water for agriculture and industry. The advanced treatment helps protect downstream water quality and ecosystems.

ANET discharges into the local watercourse that feeds into the Eure River, a tributary of the Seine. The Seine basin is a major hydrological system in northern France, supporting agriculture, urban centers, and biodiversity. The river flows into the English Channel via the Seine estuary, which is an ecologically sensitive area for migratory fish and bird species. Advanced treatment at ANET helps reduce nutrient loading and protects downstream habitats.
