SAINT FARGEAU PONTHIERRY is a wastewater treatment plant located in Boissise-le-Roi, a commune in the Seine-et-Marne department of north-central France. The plant serves a population equivalent of 13,648, placing it in the medium agglomeration category under EU regulations. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent between 2,000 and 15,000. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas, such as those subject to eutrophication. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Seine River. The Seine flows through Paris and into the English Channel, supporting diverse aquatic life and serving as a vital water resource for the region. The plant plays a key role in protecting downstream water quality and ecosystems.
Environmental context
The plant discharges into the Seine River basin, which flows through the Île-de-France region and eventually reaches the English Channel. The Seine supports a variety of fish species and is an important migratory corridor for eels and salmon. Downstream, the estuary and bay provide critical habitat for birds and marine life, making effective wastewater treatment essential for maintaining ecological balance.
