Overview
VENEUX LES SABLONS wastewater treatment plant serves the Moret-Loing-et-Orvanne area in Seine-et-Marne, France. It treats wastewater for approximately 10,800 people under the EU Urban Waste Water Treatment Directive.
VENEUX LES SABLONS is a wastewater treatment plant located in Veneux-les-Sablons, part of the commune Moret-Loing-et-Orvanne in the Seine-et-Marne department of north-central France. The plant serves a population of around 10,800 residents, placing it in the medium agglomeration category under European Union regulations. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. Compliance with the directive ensures a minimum level of treatment. The treated effluent is discharged into the Loing River, a tributary of the Seine. The Seine River basin is a major hydrological system in northern France, ultimately flowing into the English Channel. The Loing River supports diverse aquatic life and is an important ecological corridor within the region. Proper wastewater treatment at this plant helps protect water quality in the Loing and downstream Seine ecosystem.
Environmental context
The plant discharges into the Loing River, which flows into the Seine River, eventually reaching the English Channel. The Seine basin is a densely populated and agriculturally intensive region, making nutrient management critical. The Loing River supports fish species such as pike and perch, and its riparian zones provide habitat for birds and amphibians. Effective treatment reduces the risk of eutrophication in downstream waters.
