Overview
Dammarie Les Lys wastewater treatment plant serves approximately 100,000 people in Dammarie-les-Lys, France. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The Dammarie Les Lys wastewater treatment plant is located in Dammarie-les-Lys, a commune in the Seine-et-Marne department of north-central France. The plant serves a population of approximately 100,287, classifying it as a large agglomeration under EU regulations. It is situated near the Seine River, which flows through the Paris metropolitan area. As a facility serving over 100,000 people, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For sensitive areas, tertiary treatment may be mandated to reduce nutrient loads. The regulatory framework ensures compliance with discharge standards. The plant discharges treated wastewater into the Seine River, which flows northwest through Paris and eventually into the English Channel via the Seine estuary. The Seine basin supports diverse aquatic life and is an important ecological corridor in the region. The plant plays a key role in protecting water quality in this densely populated and industrialized area.
Environmental context
The plant discharges into the Seine River, which flows through the Paris region and drains into the English Channel. The Seine basin supports a variety of fish species and is a critical habitat for migratory birds. Downstream, the Seine estuary is an ecologically sensitive area that requires careful management of nutrient and pollutant loads to prevent eutrophication and maintain biodiversity.
Frequently asked questions
The plant is located in Dammarie-les-Lys, a commune in the Seine-et-Marne department of north-central France, near the Seine River.
The plant discharges treated wastewater into the Seine River, which flows through the Paris region and ultimately reaches the English Channel.
The plant protects the Seine River and its downstream ecosystems, including the Seine estuary, by treating wastewater before discharge.
As a large agglomeration serving over 100,000 people, the plant is required to meet secondary treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). In sensitive areas, tertiary treatment may be required to reduce nutrient pollution.
In France, plants serving large agglomerations typically employ secondary biological treatment, often with nutrient removal to comply with EU directives. Many also include tertiary treatment for phosphorus and nitrogen reduction.
