Lardy Janville Bouray Wastewater Treatment Plant, Bouray-sur-Juine, France

Lardy Janville Bouray is a wastewater treatment plant located in Bouray-sur-Juine, a commune in the Essonne department of Île-de-France, France. The plant serves a population of around 7,072 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The facility is situated in the Paris Basin, a region with temperate climate and mixed urban-agricultural land use. As a plant serving fewer than 10,000 population equivalents, it is subject to the EU UWWTD requirements for appropriate treatment, typically secondary treatment or equivalent. The plant operates within the French regulatory framework, which implements the directive through national legislation. The plant is expected to meet the standards set for its size category. The treated effluent is discharged into the local watershed, likely the Juine River, a tributary of the Essonne River, which flows into the Seine River and eventually reaches the English Channel. The plant plays a role in protecting the water quality of the Seine basin, which supports diverse aquatic life and is important for downstream ecosystems and water uses.

The plant discharges into the Juine River, a tributary of the Essonne River, which flows into the Seine River. The Seine basin is a major hydrological system in northern France, supporting diverse aquatic habitats and providing water for agriculture, industry, and drinking water. The downstream environment includes sensitive ecosystems such as riparian zones and wetlands that benefit from effective wastewater treatment to maintain water quality and ecological balance.
