Overview
ORGERUS wastewater treatment plant serves Orgerus, Île-de-France, France. It provides advanced treatment for a population of 4,180 with a designed capacity of 6,000 m³/day.
ORGERUS is a wastewater treatment plant located in Orgerus, within the Île-de-France region of France. The facility serves a population of approximately 4,180 residents and is part of the municipal wastewater infrastructure for the commune. It is situated in the Yvelines department, near Mantes-la-Jolie. The plant operates with advanced treatment processes, meeting high standards for effluent quality. Its designed capacity is 6,000 m³/day, with a reported discharge volume of 745.70 m³/day, indicating it is operating well below capacity. As a French facility, it complies with national regulations transposing the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. The treated wastewater is discharged into the local watershed, which ultimately drains into the Seine River basin. The Seine flows through Paris and into the English Channel, supporting diverse aquatic life and providing water for various uses downstream. The plant's advanced treatment helps protect the receiving water bodies from nutrient pollution and other contaminants.
Environmental context
The plant discharges into the Seine River basin, which flows through Île-de-France and eventually reaches the English Channel. The Seine supports a rich ecosystem, including fish species such as pike and perch, and is an important migratory corridor for eels. Advanced treatment at ORGERUS reduces nutrient loads, helping to prevent eutrophication in downstream waters and the coastal zone.
