The LIFE ADSORB project explores a number of aspects in order to gain a comprehensive view of stormwater treatment using a reed filter. The results obtained are presented in this section.
The implementation of European environmental policy is carried out through the LIFE programme, its main instrument for the environment and the protection of nature.
Based on ecological engineering, the Life Adsorb prototype combines “grey techniques” and “green techniques”. It includes storage of the water to be treated in existing sanitation infrastructures.
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.
Order to preserve the quality of the Seine, it has become necessary to treat pollutants (macropollutants and micropollutants) from a busy road, a section of the Paris ring road. The chosen purification solution is a vertical reed bed filter located in the heart of the Bois de Boulogne.
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.
With an initial duration of 5 years (July 2018 - July 2023), the project has been extended to September 2025.
