Overview
BRUYERES SUR OISE wastewater treatment plant serves Bruyères-sur-Oise, France. It treats wastewater for approximately 9,630 people under the EU Urban Waste Water Treatment Directive.
The BRUYERES SUR OISE wastewater treatment plant is located in Bruyères-sur-Oise, a commune in the Val-d'Oise department of northern France. It serves a population of approximately 9,630 residents as part of the region's municipal wastewater infrastructure. As a plant serving a medium agglomeration (between 2,000 and 10,000 population equivalent), it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC. This directive requires secondary treatment for discharges to freshwater and estuaries, with more stringent tertiary treatment if the receiving water is designated as sensitive. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Oise River, a major tributary of the Seine. The Seine River flows through Paris and into the English Channel, supporting diverse aquatic ecosystems and serving as a critical water resource for the region.
Environmental context
The plant discharges into the Oise River basin, which flows into the Seine River and eventually the English Channel. The Seine estuary and downstream marine environment support important fisheries and migratory bird populations. The watershed is subject to nutrient management regulations under the EU Nitrates Directive to prevent eutrophication in coastal waters.
