LE TRAIT Wastewater Treatment Plant, Le Trait, Normandy, France

LE TRAIT is a wastewater treatment plant located in Le Trait, a commune in the Seine-Maritime department of Normandy, France. The plant serves a population of approximately 9,100 people and has a designed capacity of 1.00 m³/day. It is situated near the Seine River, which flows through the region and ultimately drains into the English Channel. As a French wastewater facility, LE TRAIT operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 10,000. For plants serving around 9,100 people, secondary treatment is the standard, ensuring the removal of organic matter and suspended solids before discharge. The plant's treated effluent is likely discharged into the Seine River or a tributary, contributing to the water quality management of the Seine basin. The Seine flows through Normandy and into the English Channel, supporting diverse aquatic life and serving as a critical water resource for the region. Proper treatment at LE TRAIT helps protect downstream ecosystems and recreational uses.

The plant is located in the Seine River basin, which drains into the English Channel. The Seine supports a variety of fish species and is an important migratory corridor for Atlantic salmon and eels. Downstream, the estuary and coastal waters are ecologically sensitive, hosting rich biodiversity. Effective wastewater treatment at LE TRAIT helps reduce nutrient and pollutant loads, safeguarding water quality in the river and the marine environment.
