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.
