The Life Adsorb project is part of an environmental approach, which is why it was chosen to integrate the European Life program. An impact study carried out on the site allowed the project to follow an environmentally friendly approach by fitting harmoniously into the landscape.
The challenge of the demonstration is significant: to show the compatibility between the objectives of biodiversity preservation, heritage conservation, and social well-being with those of water treatment.
The previous studies conducted by the Water and Sanitation Technical Department of the City of Paris between 2011 and 2014 defined a comprehensive project for storing effluents in the Bugeaud storm overflow (SO), followed by their treatment using a reed bed filter, before discharging the treated effluents into the hydrographic network of the Bois de Boulogne and then into the Seine. The location for the reed bed filter was determined in 2014 in consultation with the Architects of the Buildings of France (ABF) and the Site Inspector.
The City of Paris carried out a sanitation works program between July 2018 and December 2020 in the northeastern part of the Bois de Boulogne. The objective was to reduce pollutant discharges into the Seine from the Bugeaud storm overflow (SO) and to eliminate the discharge of clear water from the Saint-James pond and the Neuilly pond into the combined sewer system of the municipality of Neuilly-sur-Seine.
In Paris, an area that is emblematic of environmental issues in urban areas, the Bugeaud storm overflow crosses the Bois de Boulogne. It discharges rainwater from a section of the ring road directly into the Seine, and on rare occasions wastewater. To improve the management of urban discharges during rainy weather, the City of Paris has planned to upgrade the spillway by equipping it with a storage system and filtering water before it is discharged into the Seine.
