SACY LE GRAND is an advanced wastewater treatment plant located in Pont-Sainte-Maxence, within the Oise department of Hauts-de-France, France. The facility serves a population of around 4,183 and has a designed capacity of 3,000 cubic meters per day, with a reported discharge volume of 746.24 cubic meters per day. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients and other pollutants, aligning with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The plant operates under French regulations, which transpose the directive and mandate appropriate treatment levels based on the receiving environment. The plant discharges treated effluent into the local watershed, which ultimately drains into the Oise River, a major tributary of the Seine River. The Seine flows through the Paris region and into the English Channel, supporting diverse aquatic life and providing water for various uses downstream.
Environmental context
The plant's treated effluent enters the Oise River basin, which flows into the Seine River and eventually reaches the English Channel. This watershed supports a variety of aquatic species and is important for regional water quality. The advanced treatment level helps protect the downstream environment by reducing nutrient loads that could cause eutrophication in the Seine estuary and coastal waters.
