Paris has officially reopened its Seine River for public swimming this summer, a landmark moment following a major cleanup initiative for the 2024 Olympics. The river, which was once heavily polluted, is now deemed safe for swimmers after significant investments in sewer systems, water treatment facilities, and rainwater management. This marks the first time since 1923 that public swimming has been allowed in the Seine, offering visitors a unique experience near iconic landmarks like the Eiffel Tower.
The cleanup effort was spearheaded by French authorities and included the connection of tens of thousands of homes to the sewer system, the upgrade of water treatment facilities, and the construction of rainwater storage reservoirs to prevent sewer overflow during heavy storms. These measures were crucial in ensuring that the water met the standards required for both Olympic events and public use. During the swimming season, daily water tests will be conducted, with green and red flags indicating which areas are open or closed to swimmers.
The reopening has already attracted attention from international visitors and locals alike. A 24-year-old Brazilian resident of Paris expressed surprise and admiration, stating, ‘Really nice, I’m impressed, surprised. I never imagined being in the water close to the Eiffel Tower.’ A 51-year-old woman noted that the water was ‘clean, warm, and clear,’ although she mentioned the presence of some algae, which she called ‘normal.’
Outside of Paris, 14 swimming sites have been set up along the Seine and Marne rivers, with a couple already open. This expansion of the initiative aims to provide more access to the river while ensuring continued water quality. The move reflects a broader commitment to environmental restoration and public health, as well as a demonstration of France’s ability to balance urban development with environmental sustainability. As the summer season progresses, the city will continue to monitor water conditions to ensure the safety and enjoyment of all swimmers.
