Overview
Fontenay-Trésigny wastewater treatment plant serves approximately 8,670 people in Seine-et-Marne, France. The facility operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The Fontenay-Trésigny wastewater treatment plant is located in the commune of Fontenay-Trésigny, in the Seine-et-Marne department of the Île-de-France region. It serves a population of approximately 8,670 residents, classifying it as a small to medium agglomeration under French and EU regulations. As a plant in France, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater and estuaries for agglomerations above 2,000 population equivalent. The regulatory framework ensures appropriate treatment standards are met. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Seine River basin. The Seine River flows through Paris and into the English Channel, supporting diverse aquatic life and serving as a critical water resource for the region. The plant plays a key role in protecting downstream water quality and ecosystems.
