Aubergenville Wastewater Treatment Plant, Île-de-France | France

The Aubergenville wastewater treatment plant is located in the Yvelines department of Île-de-France, France, serving the commune of Aubergenville and surrounding areas. With a population equivalent of approximately 14,443, it falls under the EU classification of a medium agglomeration, requiring appropriate treatment standards to protect the local environment. As a French wastewater facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets minimum treatment requirements based on population size and receiving water sensitivity. For agglomerations between 10,000 and 150,000 population equivalent, secondary treatment is typically required, with tertiary treatment in sensitive areas. The plant's design and operation are regulated by French authorities, ensuring compliance with national and European standards. The treated effluent from the Aubergenville plant is discharged into the local water system, ultimately flowing into the Seine River basin. The Seine River is a major waterway that drains into the English Channel, supporting diverse aquatic life and providing water for agriculture, industry, and recreation. The plant plays a crucial role in maintaining water quality in this densely populated region.

The Aubergenville plant discharges into the Seine River basin, which flows through Paris and eventually reaches the English Channel. The Seine supports a variety of fish species and is an important ecological corridor in the Île-de-France region. Downstream, the estuary and bay provide habitat for migratory birds and marine life. Protecting water quality in this basin is critical for both ecological health and human uses such as drinking water and recreation.
