Overview
GAZERAN La Gueville wastewater treatment plant serves approximately 26,000 people in Gazeran, Île-de-France, France. It operates under the EU Urban Waste Water Treatment Directive.
GAZERAN La Gueville is a wastewater treatment plant located in Gazeran, within the Rambouillet area of Yvelines, Île-de-France, France. The facility serves a population of around 26,000, classifying it as a medium agglomeration under EU regulations. Situated inland, the plant is more than 50 km from the coast, reducing direct marine discharge risks. As a French plant serving over 10,000 people, GAZERAN La Gueville is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum. For agglomerations of this size in sensitive areas, tertiary treatment may be required to reduce nutrient loads. The regulatory framework ensures compliance with European standards for effluent quality. The treated wastewater from GAZERAN La Gueville likely discharges into local watercourses that feed into the Seine River basin, ultimately reaching the English Channel. The Île-de-France region is densely populated and ecologically sensitive, with the Seine supporting diverse aquatic life and providing water for agriculture and recreation. Proper treatment at this plant helps protect downstream ecosystems and water quality.
Environmental context
The plant's treated effluent flows into local streams within the Seine River basin, which drains into the English Channel. The Seine watershed supports diverse aquatic species and is a critical resource for the Paris metropolitan area. Nutrient and pollutant control at this plant is essential to prevent eutrophication and maintain water quality in downstream rivers and coastal zones.
