Overview
Montataire wastewater treatment plant serves 79,800 people in Hauts-de-France, France. The facility operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The Montataire wastewater treatment plant is located in the commune of Montataire, within the Oise department of the Hauts-de-France region in northern France. It serves a population of approximately 79,800, classifying it as a medium-to-large agglomeration under EU classification. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary biological treatment for agglomerations over 2,000 population equivalent. For a plant serving nearly 80,000 people, compliance with tertiary treatment standards may also apply if the receiving waters are designated as sensitive areas under the directive. The treated effluent is discharged into the local watershed, which ultimately drains into the Oise River, a major tributary of the Seine. The Seine River flows through the Paris Basin and into the English Channel, supporting diverse aquatic ecosystems and providing water for agriculture and industry along its course.
Environmental context
The plant discharges into the Oise River basin, which flows into the Seine River and eventually reaches the English Channel. The Seine estuary and downstream marine environment support important fisheries and migratory bird populations. The watershed is ecologically significant, with wetlands and riparian zones that provide habitat for species such as the European eel and various waterfowl.

The Montataire WWTP serves approximately 79,800 people, classifying it as a medium-to-large agglomeration under EU classification.
The plant discharges into the local watershed that drains into the Oise River, a major tributary of the Seine. The Seine flows through the Paris Basin and into the English Channel.
As a French facility serving nearly 80,000 people, the Montataire plant must comply with the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations over 2,000 PE and potentially tertiary treatment if the receiving waters are sensitive areas.
In France, wastewater treatment plants serving agglomerations of this scale typically employ secondary biological treatment, such as activated sludge, and may include tertiary treatment like nutrient removal or disinfection if required by the sensitivity of the receiving water body.
